3.1 Overview
Regardless of the various standards promoted in the production of drilling products, when the basic kinetic energy will be listed as a geometric series for each generation of dimensions, the use of priority number systems has advantages. 3.2 The best series
From the perspective of planning God 4, as well as the speed of the auxiliary value group, the performance of the best element is guaranteed to be accepted as much as possible,
3.3 Widely note the applicability
Prefer the method with the strongest material resistance to meet the overall medicinal requirements in a given rated or internal (motor power, pushing capacity, etc.).
3.4 Simplify technical and commercial calculations
The standard and commercial definition of the priority number is also the priority number, so it can be used to calculate the efficiency value instead of the priority number itself, and the series! Only inch, clothing price, etc.> According to the expansion ratio, multiplying the relative courtyard, the calculation is greatly simplified. 3.5 Convenient for conversion of measurement units
When the measurement unit value is optimal and the conversion factor is approximately the optimal number, it can be used to convert other measurement units. 4 Application of rounded values
4.1 Overview
Rounded values Rounded values are only used in certain situations. Rounded values should be used first. 4.2 In some certain occasions, the optimal number cannot be used for important reasons:) When the number to be used is not possible to obtain all the effective digits (the number of effective digits is not possible to obtain all the effective digits) For the number that needs to be called, the whole number and the items that require the effect of divisibility or addition, sometimes it is appropriate to use the rounded value ratio, for example, the combination of the size of the unit and the integer multiple of the weight is only one. CE/1:19764·2005/1SO 497:1973 Where tolerances are required, the number of significant digits of the optical number has no practical significance and is not easily quantified, and the rounded value series can be used. For example, the optical time of a photographic image is 1/30 to 1/31.5 seconds, and the 0/3 series [1.1.:2, 1/4.1/3.1/15, 1/x0, 1/60, 1/-25..-.--shift..3] is used. If the product range is limited by the existing material basis and the existing material basis is not easy to change (for example, considering the economical performance, the existing flash quantity is still fast), the rounded value series can be used. If the standard diameter is within the standard length series
4.4 within the important range (4.2), it can be considered that the rounded value series is appropriate. If economic and psychological factors are considered and a simpler form of expression is used, especially when there are reasons for reducing the use of numbers in the document), it is not necessary to use rounded values, because this may cause inconsistencies in corporate standards and national standards, which will have a great impact on international technical exchanges and product retention. International standards and technical documents are based on preferred numbers. The current national standards also use preferred numbers, which are consistent with international standards, but are not modern and advanced! To achieve consistency, if the state-when the public hopes to change the current system (such as physical constants! Introduce the interpersonal promotion and make these effective values approximate the optimal number or its rounded value, the department should not consider the "optimal number" of the optimal number as a "form of currency". This series cannot be used to illustrate the entire quality of the color of the first light teaching. The production day and month will have a shift, especially in the calculation detailed in 3.3. This also applies to the aforementioned difficult to change series of gear numbers. 5 Selection rules and rounded value series decay
5.1 Choose a typical effective value to meet the specific requirements of the type. 5.1.1 Select the appropriate ratio in the following order: 5 10--2043
5.1.2 Select the system with appropriate requirements and common ratio (see clothes:), that is: "Preferentially use the preferred number system itself (1 Note):) If there are sufficient reasons and the optimal light coagulation cannot be used at all, use the first value series R) and finally use the second value series.

"If there is a rounded value in the series, or a special feature that meets the requirements of the state is allowed to exist, the four are not preferred ~ , it is impossible to convert it into a series with a smaller common ratio. 6.2 The uniformity of the whole value series is better than that of the optical series, because the relative supply difference of the series in some intervals can reach 2.94, which is closer to R\ Series can reach 5, center 1%\.
6.3 Uniformity of derived series classification One long or R series blank class, false If you reverse the two adjacent items, for example, one downward and 5 upward; taking the 40/4 series (1.05) as an example, the relative error between 1.25 and 1.7 is 1.26% + 251% = 3.?7, while the original 40 series range is only 2.9 when the return difference is relatively large, and the acid also makes up for the system's performance. The precision of the 6.4-level value is not as good as the modern laser In fact, the reduction of the overall value can reach 2.1% in the K series and 5.3% in the R series. When calculating the numbers given in the fifth column of Table 1, the integer cannot be used to set
6.5 as the solution. If you choose the same integer value instead of the priority number, it will cause great difficulty in the coordination of the time.

Production and ratio uniformity of item values
GB/T 19764—2005/ISQ 4971973 In order to use the chemical formula for the above-mentioned ring solution and the non-chemical formula, the calculation should be studied first. The relative value of the chemical formula relative to the theoretical value is called the index of the variable value. A1.2 The precision of the value of the item relative to the theoretical value can be expressed as a relative relationship described in percentage, using the ratio of the difference between the item and the theoretical value to the theoretical elimination. Ratio expression:
Priority and relative error are listed in the 8th column of Table 1 of GB/T3212J5 and are repeated in the 1st column of the table of this standard. The relative difference of the chemical value is listed in the vehicle mark Table 10, columns 8-11, A, 1.3 The difference between the actual common ratio (corresponding to the directivity of the state item) and the theoretical common ratio at a given point in a series of ratios is the difference between the actual common ratio at that point and the theoretical common ratio. White ratio represents\:||tt || According to the common ratio and the error of the two, the value of the item in the 7th to 11th column of Table 1 can be used to read the standard single algebraic subtraction to find the value (slightly larger than the left small amount!"||tt| |R, R, R\ The common ratio of each series at the last point is recorded in the current table 1.

A.5.1 The small fraction may be rounded only under special circumstances. Other instruments have two significant digits, and some even have only one. The effective characters are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 5.2 The deviation from the theoretical value is calculated by the deviation from the priority number (the maximum reading difference in the cells from the 7th to the 10th columns of Table 1). The common ratio of the R and R\ series is the priority series difference. Very needed, such as R\5. Most people are not due to hooking (see the last column of the first to fourth columns of Table 1> up to 5.37%, mRF only 1.2%, R10 up to 2.94%. mR40 only 1.15% A.5.3 It should be noted that the integer of the fast month is allowed in R5 or k\10: in the denser series, it is not allowed to use it, and the error of 1.5 relative to the ten-block is 5.36, which causes 5.60 with the continuous term, 3 sets % of the common ratio is relative to the error ticket. This is a good match for the R\1 series with a common ratio of 1. Because according to A.2.1[\10, the maximum allowable error is 12,D%, but the value of 1.5 cannot be guaranteed, so the convention is 1.12* In the R23 series, it causes a 63% relative error for the 1.8 continuous ticket, while the error for 1\20 is only 6.1%.

A given value is selected. When there is no suitable value in the preferred rounding, the rounded value can be selected. 6. The harm of using the rounded value
6. "If there is a rounded value in the series, or a special feature that meets the requirements of the state exists, it is not a priority, and it is impossible to convert it into a series with a smaller common ratio. 6.2 The uniformity of the rounded value series classification is better than the numerical series, because the relative difference in some intervals can reach 2.94, and the R\ series can reach 5, and the center is 1%.
6.3 The uniformity of the derived series classification is a long or R series. If the series is empty, For example, if two adjacent items are reversed, one is downward and the other is upward; taking the 40/4 series (1.05) as an example, the relative error between 1.25 and 1.7 is 1.26% + 2.51% = 3.7, while the original 40 series range is only 2.9%, which also makes up for the principle of system compatibility. The precision of the 6.4 value is not as high as that of the original light. In fact, the reduction of the precision of the whole value can reach 2.1% in the K series and 5.3% in the R series. Moreover, due to the above situation, when the number given in the fifth column of Table 1 is to be calculated, the whole value cannot be solved by setting the product value of 6.5. If you choose the same rounded value instead of the priority number, it will be difficult to coordinate the pressure between the two standards.
3) The error of the rounded value of the linear scale is: the area and the control of the control area are 155, the product of the power is greater than 155, the product of the power is greater than 2: the product of the power is greater than 2. The inertia of the spring is greater than 2. See 2. Miscellaneous Note 2),

A1.2 The accuracy of the value of the same item relative to the theoretical value can be expressed as a relative relationship described in percentage, expressed as the ratio of the difference between the item and the theoretical value to the theoretical elimination:
The relative error is listed in the eighth column of Table 1 of GB/T3212J5 and is listed in the eighth column of Table 1 of this standard. The relative difference of chemical correction values is listed in the eighth to eleventh columns of Table 10 of the standard. A1.3 The accuracy of a series of common ratios at a given point is expressed as the percentage between the actual common ratio (the vertical of the corresponding item) at that point and the theoretical common ratio: ||tt || According to the table, the error between the common ratio and the value of the product can be obtained by algebraic subtraction of the values given in the 7th to 11th columns of Table 1 (slightly larger than the left and right smaller amount!

A.2.1 If such a condition is given, that is, the error of the value should be smaller than the error of the adjacent current value, this condition can be expressed by the maximum allowable error, and the common value can be approximately equal to 10 when the common ratio V1C is too large. -:

However, it still maintains sufficient uniformity in R and \: \4. 5.2 The deviation of the rounded value from the theoretical value exceeds the maximum reading difference in the preferred series (note the maximum reading difference in the 7th to 10th columns of Table 1). The common ratio of R and R\ series is very different from the preferred series, such as R\5. The most common ratio (see the last column of the 1st to 4th columns of Table 1) is 5.37%, mRF is only 1.2%, R10 is 2.94%, and mR40 is only 1.15%. A.5.3 It should be noted that the rounded value of 1.5 relative to the theoretical value is 5.36, which causes a relative error of 5.60% with the continuous term 3. This is true for the R\1 series with a common ratio of 1. Because according to A.2.1[\10, the allowable error is 12,D%, but the value of 1.5 cannot be guaranteed in the series with a common ratio of 1.12*R23. Because it causes a 63% error in the ratio of the subsequent ticket 1.8, while the allowable error of the quantity of 1\20 is only 6.1%.
