Impedance dissolution coulometry
This standard specifies the measurement of the conductivity of the metal layer by the coulometry method. This method only uses the conductive layer of the selected standard. The other components can be used together. When testing the maximum concentration of the composite material, the standard can be used, or the new composite material developed for these periods can be tested: in both cases, the adaptability of the system to the stability test needs to be verified, and this standard also describes the system in general. For example, if the alloy contains multiple layers, it is difficult to verify the existence and sequence of the expanded layers due to the different operation limits or the difficulty in obtaining the original alloy. In some cases, the standard can be used to verify the existence and sequence of the expanded layers. The shape and properties of the composite can also be tested in the same way as in 8.?.

3 The following terms are used in this standard. 3.1 The measurement area is the area of the upper surface of the continent. The size of the measurement area of the force method is the area covered by the electrolytic air seven diagrams. The surface theory of the method is to use the root of the spiral material to determine the area of the wing benefit layer: the change of the battery water is used to determine the complete retention of the warm cover layer. The degree of theft of the layer is calculated by the corresponding heart (in terms of library). The self-quality is calculated according to the following items) if a certain electrical range is used: self-operation opening and inspection can be confirmed by the country when the war order is stopped: 1: the cumulative amount of electricity entrusted to the solution of the love cover layer,
5 pastoral device
5.1 The non-visual limit of the Sichuan Province can be assembled into a suitable device, and only the special curtain is used (except for B. 5.2 The straight-type instrument usually uses the electrolyte stored before manufacturing. The North Ground should remember the amount of source area only 1 within the solution layer. The amount consumed can be converted into any single unit. The measurement area is usually any inverse unit. The benefit layer sequence is calculated using conversion coefficients or tables. The type of instrument relies on the tour, and the root cause is the filter army. The re-thickening process is through the use of electric instruments to test the thickness of the test rod. If the instrument thickness value and the known thickness of the test are not more than + 5%, the instrument does not need to be adjusted. The cause of the difference is: the special instrument should be calibrated according to the instructions of the manufacturer. The cover layer to be tested should be the same as the substrate, and its uncertainty should be less than or greater than 5%. If the alloy is lost, the correct test sample element should be used. The screen liquid should be used according to its known average, long storage life, and have no external flow. The metal coating will not react;! The new high efficiency is not likely to be close to 100%! When the solution penetrates the substrate before the H layer is fully covered, the H layer is completely covered, the electrolyte is stirred, and the electrolyte flow is confirmed in the test. The thickness of the electrolyte is determined by the end of the test. The radio waves used at the end of the test surface are only for the small project. The better the system, the better the maintenance selection of the solution. ? The accuracy of the film purchase quantity is low, the quantity is trustworthy, and the value of the layer of text is large. In the daytime, the user can receive the scientific erosion or edge of the industry, and the choice of the limit seven depends on the perception of the companion's opinion. Improving the dripping speed, that is, increasing the test current density, can save the cost of avoiding the phenomenon of 7.2 Current change
CB/T4955-2035/ISO2177.2003
No need to use the position light self-flow and timing measurement technology, the current change is not enough, the position of the electric washing boundary is too large. If the current change is too large, it may change the efficiency or the end point of the light. If the decision is: 7.3 Area change
The accuracy of the measured area will not be higher than the accuracy of the original area measured. Due to the wear of the three-way system, the area of the seal may be affected by the force of the measurement module. If the design of the interruption cell enables the seal seat to give a clear measurement area, the average accuracy of the measurement will be higher. Under these circumstances, the overall measurement may be compensated with the corresponding compensation. Connect: Under the condition of the product, make the clever collection correction standard fast tax, industry match through the benefit of the fixed:: the difference or to the most of this Qi Yanan worry about the TF series open to the real Chen Tong note the first bucket double. The mountain clothes face no courtyard return here, 7.4 mixing (if required》
inappropriate data selection will lead to the wrong end point
7.5. The alloy layer of the cap layer and the substrate is designed to have a clear interface between the substrate and the substrate. If the interface between the cap layer and the substrate is clear, the thermal conductivity of the cap layer can be controlled. The final compensation of the base metal layer may occur in the base metal layer, resulting in a higher thickness value of the active alloying cap layer. The yield flow can be used to achieve a pure body pressure change. The purity of the cap layer can be changed by the high-pressure test of the co-deposited metal. The electrochemical performance and yield of the metal can be changed. The test results show that the state of the cap layer is grease, slick layer, wide product plate light ingredients, grease conversion, and the catalysis of the cap layer will be disturbed by the test. 7.8 Density of the overlay material
is a linear function of the thickness of the overlay material. The density of the overlay material is proportional to the thickness of the overlay material. The density of the overlay material will fluctuate linearly with the thickness of the overlay material. The density of the overlay material will fluctuate slightly but significantly with the thickness of the overlay material. 1.9 Density of the electrolytic cell
is a function of the thickness of the overlay material. The density of the overlay material is called the metal product.
