appearance test
1.Effects of each component content in solution, process conditions, power source on appearance of Sn deposit were studied by Hull Cell test.
2.Additional, still have large intestine cancer, especially right half colonic cancer, often have the appearance that constipation and diarrhoea appear alternately, test of defecate concealed blood lasts electropositive (demonstrative far end is colonic have haemorrhage) , some can touch in right abdomen reach bump, accompany have tenderness, constant fallibility examine is wrapped for appendix piece.
3.Quality evaluation and audit for Vehicle samples: The items include paint appearance, sheet metal, interior/ exterior trim, static squeak& rattle/ function, engine compartment/ underbody, drive test, water test and so on.
4.Standard test environment condition is 20±3℃, humidity 40±10% (RH) and standard test position is appearance of figure 1.
5.The effects of the bath composition, complexing agent content, current density, and temperature on the appearance and Ni content in the plating were investigated making use of Hull cell test, weight method, and spectrophotometry.
6.This paper describes location and appearance of the are discharge faults in 500kV GIS, discusses the reasons of arc failures and suggestes the test procedure for GIS with higher rated voltage(≥300kV). The ac voltage is used for conditioning or ac votltage withstand test and then oscillating switching impulse voltage withstand test is carried out.
7.The test mechanisms of capacitor evenness tester and EIB photoelectric yarn appearance tester are analyzed. The capacitor evenness tester gives out the mean volume or mass of yarn section in test scope, but the EIB photoelectric yarn appearance tester reveals the diameter variation of yarn projection area, these two methods reflect the different property of yarn evenness, and their results are not in be in accordence.
8.With development of the semiconductors industry and appearance of new ASIC, SOC devices the paper analyzes new requirement and challenge proposed by IC test, and described new solution of the ATE and new system feature also.
9.The appearance and its evaluation of typical facture surface were analyzed by Drop-weight tear tests (DWTT) on thick wall X70 high-grade steel line pipe. Furthermore, the effects of wall thickness and test temperature on the appearance of facture surface were studied.
10.With the development of computer-aided test (CAT) technique, the test technique of electro-hydraulic servo valve has made a great progress, also gone up to a new high level with the appearance of virtual instruments technique.
