【Abstract】 The load characteristics of both constant-rate-of-elongation(CRE ) and constant-rate- of- traverse (CRT)strength testers are analysed and calculated.The reason for the difference between their results was found out. The test method and results for verifying the analysis are also introduced.更多还原
