Since the previous Jingguang title For the public, you have not been widely used in many fields. The success of this technology lies in its ability to treat various non-optical particle systems, and it can be used in commercial devices such as self-service and home appliances. Only the positive angle of the device can be used. The positive angle of the result needs to be carefully avoided. Therefore, it is necessary to establish an international standard for the use of the wrong light, and provide a new method for controlling the quality of the particles.

After obtaining a representative sample of the size in the dry film, it is separated in a suitable medium or gas with appropriate equipment, and a monochromatic beam (more often a laser) is passed through it. The light is pre-scattered and distributed at different points. A regular multi-element detector receives the corresponding values at these multiple points and records the values. Using appropriate optical models and mathematical procedures, the point numbers are calculated to obtain the ratio of the volume of the sample at each degree to the total volume, thereby obtaining the particle size distribution.

GB/T1937712008/1801 3320-11999 This is the most regular structure of the light, the light mouse (a glue is a light emitting) is transported through the subsequent beam of light class, the phase, half of the light ball, the normal light chain development, the need to gather, pass, expand the most close to the girl's light to form a single particle, there is a representative of the sample of the British most Maid added original hall, for the transmission of the individual fluid or gas) through the measuring area of the light, this measuring area is effectively working,
there is a representative of the moon song light page direct technology to sit the most real measurement, such as the night guest, the gas content and the bubble in the body of the glue. , in addition, the whole sample is added with porous liquid, soft objects and objects, etc.), and can be separated in an appropriate amount (see the attached test, the separation requires maintenance) and the machine is pulled and sounded) or both are used together to separate and form a stable separation state. For this system, please use a ring system. This system is an optical mass spectrometer with a separator and an ultrasonic generator. The system and the special powder separator are used. The machine is used to separate the powders. The shape of the sample is the most polite, and there is a certain way to give the sample a certain delivery path. The separator uses compressed gas or vacuum card The quality of the beautiful particles is acid and particles, and the gas will be divided into cavities by the instrument. The gas will be used to make the huge amount of evidence. There are two ways to make the particles enter the light zone. The forbidden way is to guide the light beam into the front of the light energy zone. The auxiliary light beam will be focused behind the light environment. See Figure 35. The light is small. The disk is rusty. The leaves are carefully: The art group is taller than the workers. The way to enter the world is more effective. You can drink the light! The sky is generally shot: tt||3 bottles of pine. The protective clothing is connected to the road environment and the report group will come between the car! Figure 3 shows the structure of the improved light radiation instrument with the particle delivery method. The method is to create a worry in the effective working range of the selected energy, allowing the evaluation to have a wide sensitive time zone. The first method has a certain amount of medical control time for the wide virtual space before the single shot can be sheared to a large angle of the self-release time, and the dosage is not effective. The first method is mainly used for the protection method. If the light path is reasonably designed, the jet flow can also be thrown away. The light composition is relatively good after the test, and the color is not strong at the angle of the new round (see time A). Therefore, the shot is ma Qixing Beixian Shengmu

There is only one diode that is combined with a moving diode. The photodiode converts the light intensity in the space into a series of photocurrents (,). Then, the photoelectric circuit is amplified and digitally converted into a quantity of energy. According to this, the central unit is used to determine the appropriate light intensity. This degree can be used to calculate the optical quality! , there is only a set of central unit with a special set of mobile detection to create a positioning device, this detection unit is used for storage and calculation, the computer can control the instrument automatically, store the signal received by the operator, and use the optical control type. It contains a single body to provide a medium-level light quantity, the detection training system can be seen, the calculation of the degree of maintenance (see Appendix 3. The theoretical basis of laser emission), of course, also provides the automatic operation of the relevant instrument, from different manufacturers! The key codes and software of the same manufacturer with different numbers are naturally different. The specific transmitter needs to have enough accurate information to distinguish the differences. In the actual use of the neutral light emission book, the neutral light emission data is only used. 6 Working procedures
6.1 Required conditions
G.1.1 The device should be installed in a clean place with low voltage, low mechanical disturbance, low smog, and out of direct sunlight. The working area should have good ventilation. It is recommended to work on a natural optical table. The cabinet can be placed on a dry surface. The optical system will not be exposed to heavy objects such as dust.
Warning: The device should only have a low-power light source to avoid prolonged damage. Do not look at direct light or reflected light. Do not use reflective surfaces. Local radiation safety regulations should be observed. 6.1.2 The dispersant of this body is known. Various dispersants can be used as dispersants for powders. The dispersant of the body must be resistant to ℃. If a certain dispersant is used as a dispersant, it is necessary to observe the health and safety standards of the department. When using evaporable fluids, it is necessary to use ultrasonic waves inside the skin. Dangerous gas will accumulate above the surface or due to the development of the body, the health of the skin will be low, and the effect of the depth change will be reduced.
613 The gas used in the dispersant should be used to prevent common When performing the analysis, if compressed gas is used, the gas cannot contain normal particles. Any vacuum equipment should be separated from the measurement area to prevent the air it outputs from entering the measurement area. The changes in temperature caused by the intake air should be observed according to the standard. 5.2 Sample inspection, preparation, analysis and temperature 5.2.1 Visual or recorded inspection, comparison of the temperature and shape of the product, as well as the relevant test results, if accompanied by products! 5.2.2 Sample preparation For good ice cream, the sample preparation technology should be: add the light agent fully, and at the same time use a spatula to mix it. If the mixture is lost, the high agent should be added and baked. If the mixture is not lost, the high agent should be added and baked. GB/T19077.1-2308/1S013320-1,1999, the mixing agent should be added. If the mixture is not lost, the high agent should be added and baked. GB/T19077.1-2308/1S013320-1,1999, the mixing agent should be added. If there is a blue end teaching product in the ancient Zhao out of the United States standard country, the determination I read the particles out of the tour, you can use a simple division, but choose the current determination to remember to ask the husband to remove some of the teaching ratio,
because, for pounds of fog, gas and other senses and children with the application of the gas tour, when sampling encounter light, do not receive the change of the needle cloth, it is almost impossible, so, only the dream time is appropriate (see .2.36.2. Clause should be directly measured according to the sleep service 6.2.3 sample division
5.2.31 under the division of the body to use gas or this rest division, the division of the rubber seat is in line with the day of the completion of the lead, for example: is the determination of the original single particle, also mutual determination of the reunion of the skin after the auxiliary teaching
6.2.3.2 operation with a very suitable release, generally is the fast moon jade air or the real car for division, it tries to throw more cutting force and frequency with the ticket between, The onboard documents of the collected samples are combined with the public documents of the road collection. For the dry powder distribution, it is noted that the samples with the characteristics of the products have the characteristics of the representative products. In order to create a lighter and wider nuclear separation, it is necessary to use the smallest number of particles and the largest reading. The sample has a certain amount of blood. For the determination of the amount of blood, the original light distribution of the sample should be determined. The distribution rate should be properly dispersed. The particle size distribution is relatively large. Usually, the dry powder distribution result is directly compared with the body dispersion result. The result is the same. Another method is to change the distribution energy (the original gas pressure), the particle size distribution change is usually increased, and the distribution energy is increased. After the distribution is determined, the low distribution rate is not affected, and the energy is increased. And the small particles increase, the midpoint of incomplete stability is the most appropriate measurement value. Note that instability does not necessarily occur (addition is the result of reaggregation or disorder). The use of selected scientific cutting village introduction leads to the process of very scattered particles. I must avoid it. 6.2.5.3 Bamboo multi-child body can be used as a large separation agent. The conditions required are as follows. Both the test and the test results will promote the separation of the fluid. The effect of the separation can be observed by the imaging system. The test can be used to quantify the suspension only. At the same time, use appropriate protective drugs: if the sample is fully separated, the slight distribution obtained by adding children should not be empty. In order to create reliable results, the minimum sample volume is required. As the separation is done The larger the size of the country, the more accurate the response needs to be. For example, the dosage form must be adjusted according to the dosage form, and the area of the sample must be the largest. For example, the sugar content of the product is preferably 2mL--20mL. At least 0.3mL of sample is required, and at least 500mL of the sample is required. The time required for the sample to be collected or the data of the instrument should be read out at the same time. The concentration of the particles in the sample should not be based on the smallest integer value. For multiple instruments, in order to obtain a signal-to-noise ratio that is slightly less than 5, there is an upper limit on the dosage. In order to avoid multiple exposures (intentional exposure to multiple particles), the value is greater than 20%! About, new smaller than the machine m, the concentration of the world forget the small 15 first, a deep feeling of multiple dare to shoot in my big sensitive corner day. If the night has how much real dare to shoot fast stop, the group of the body measured the release of the model through the real value, if the frequency point training must be determined according to the degree of style, it should be corrected in the release of more camps, the education will exist in the system I said. Figure 5 provides a preliminary calculation of the concentration. The choice of 5 is a good one. It shows the most suitable ratio of the end product to the light skin: small silencer needs low concentration. For example, when the dispersion is crisp, the road length is long, the grain true meal is close to 1, and the street winter true method is close to 0.02%. For 100% of the environment, the body skin should be close to 2%. The measurement results are reported in the book. The width of the pure tensile test city is the most important factor in the sample's natural density. The width of the environmental table is respected according to the world standard. The length of the road in the determination area, the optical properties of the grains, the combined density of the detector unit, etc. are taken into consideration. Thorn, sign in the above factors, for a nail a celebration of the material, in order to determine the most suitable new reference, should be for the non-rolling can cover the right to determine, 6

6.3.Procedure
The procedure for using the new distribution of Nandrolone is as follows: Please try the instrument and measure the blue and white
Select the appropriate series of teaching and night-time optical components, perform a blank measurement on the medium without any substance, and store the obtained signal for backup. In the future, when using the thermometer to measure the product, the signal obtained should be the white number. Only when the instrument is used can the real signal of the product be obtained. b) Make a film of the product service map
The most suitable one, only the instrument can be used in the obtained In a short period of time, I got the help of the whole scanning data, specifically 25 scans 13 times, and used the signal of each detection unit to calculate the detection image, and stored it in the computer's memory. The signal of each detection unit can be obtained by taking the accumulated light intensity and conversion effect of the detector, and the coordinates of each detection unit (degrees and position) and the appropriate angle range are determined by the program. All of these are made by the country! , The 3D images of the 1920s and 300s are of very good quality and are not very accurate. The 3D images of the 1920s and 300s are of very good quality and are not very accurate. The 3D images of the 1920s and 300s are of very good quality and are not very accurate.

E.5.2, 1 use a few meal numbers or any self-standard certificate of the international standard purchase can be played by everyone In order to change the calibration, the entire determination sequence must be checked, including the sample, sample analysis, sample selection, adjustment, and all other procedures. This card has made sufficient comments on the operation sequence.
The plastic love announced that the material has a certificate of full absorption, and its ball and purchase should have more than 10 softness models. These standard materials need to use the listed methods to forget the resistance of various virtual and other fields. The analysis should have a practical and detailed operation. If the theory is used for calculation, the disk can use the low multiple discount of the material. The precision of the consumption position, for the state according to the length of the quality or the certificate of the benefit of at least 3 people to buy the determination, the average value of the standard value is obtained. The standard is that the average value is less than 3 and the standard value is less than 5. Although it is better to use pregnant women, non-invasive tests can be used, preferably with a certificate or medical certificate, and with the corresponding progress and allowance for the new course. If other methods other than invasive surgery are used, it may produce! It is not very stable, and the original class cannot be changed. Different teeth have different spiritual attention to the frequency of light, so for the same non-invasive test, it is possible to get different effects.
Feng: Netn Special Line Non-Washing and Shepherd2. Note the above items. The teacher should check the relevant instructions during the analysis and analysis period. Also pay attention to the following matters: before turning on the power, all parts of the device should be grounded well, all the distribution devices and delivery devices, the device should be grounded, the vacuum air inlet and the vacuum channel should be grounded to prevent the main electrical equipment from igniting the whole device. After turning on the power, the time is enough to make the device predetermined. The gas light (plan LleNe dare light Ya) channel width is more than half an hour to cause heat. The device is only in a state of sinking. If necessary, the whole device should be identified and the product should be inspected.

E.5.2, 1 use a few meal numbers or any self-standard certificate of the international standard purchase can be played by everyone In order to change the calibration, the entire determination sequence must be checked, including the sample, sample analysis, sample selection, adjustment, and all other procedures. This card has made sufficient comments on the operation sequence.
The plastic love announced that the material has a certificate of full absorption, and its ball and purchase should have more than 10 softness models. These standard materials need to use the listed methods to forget the resistance of various virtual and other fields. The analysis should have a practical and detailed operation. If the theory is used for calculation, the disk can use the low multiple discount of the material. The precision of the consumption position, for the state according to the length of the quality or the certificate of the benefit of at least 3 people to buy the determination, the average value of the standard value is obtained. The standard is that the average value is less than 3 and the standard value is less than 5. Although it is better to use pregnant women, non-invasive tests can be used, preferably with a certificate or medical certificate, and with the corresponding progress and allowance for the new course. If other methods other than invasive surgery are used, it may produce! It is not very stable, and the original class cannot be changed. Different teeth have different spiritual attention to the frequency of light, so for the same non-invasive test, it is possible to get different effects.
Feng: Netn Special Line Non-Washing and Shepherd2. Note the above items. The teacher should check the relevant instructions during the analysis and analysis period. Also pay attention to the following matters: before turning on the power, all parts of the device should be grounded well, all the distribution devices and delivery devices, the device should be grounded, the vacuum air inlet and the vacuum channel should be grounded to prevent the main electrical equipment from igniting the whole device. After turning on the power, the time is enough to make the device predetermined. The gas light (plan LleNe dare light Ya) channel width is more than half an hour to cause heat.
