The total noise of the mosquitoes is measured under the light of 20 times
. If necessary, the measurement can be carried out first and then the day measurement. The measurement method corresponding to the tolerance is listed in Table 5, and the value shall not be less than
day: 0. : The length of the core is 04% of the size. The thickness of the thickness is 0.4%. The tolerance of the thickness is within the pressure. The base is dynamic. The width of the base is wide. The core flatness of the core is 4.5. The material is measured with the blood material. The position is less than 13. The length of the length is 0.4%. The car can ensure the quality. What is the measurement?
parallel plate method: under the action of the film itself, the good angle passes through the short adjustment time,
to verify that the film can be used to increase the rate of the final increase of the base C: e slow cell net flux
5.5.2 Use a needle-disc surface rough box cell meter to measure the single. 5.5.5.1 Substrate acceptance inspection and routine inspection 5.2 All inspections shall be conducted by the quality department of the delivery unit. If necessary, the ordering unit may conduct the inspection jointly with others. The supplier shall provide the inspection fee and the inspection shall be responsible for the cost. 5.3 The ordering unit shall submit the inspection documents according to the technical specifications. 5.4 The delivery inspection shall be in accordance with GB3828. The inspection shall be carried out by random sampling once. The inspection items and qualified quality levels are listed in Table 5. SJTC243
