In this paper, an analytical procedure is presented to calculate the J-R resistence curve on the basis of analysing the relationship between the three curves, the measured load-displacement curve, the imaginary load-displacement curer and the ductile crack extension-displacement curve, from one specimen.
在三曲线关联分析的基础上,提出了一种新的单试样测定J R阻力曲线的方法和步骤,编制了计算机应用程序。三曲线为:试验载荷-位移曲线;
Imaginary load method and real load method can be used to test AC sampling measurement device of integrated substation automation.
变电站综合自动化交流采样测量装置可采用虚负荷法和实负荷法检测。
