There is a fixed relationship between the gauge length and the cross-sectional area of the test-piece at the reduced diameter. 定向低频分析与测距浮标标距长度和试样在直径减少处的横截面面积之间有固定的关系。
The influence of resistance strain gauge length in strain-ring on measuring sensitivity is analysed as well. 同时分析了应变环中电阻应变计长度对测试灵敏度的影响。
In the measurement process of the gauge block, higher than the second grade and K level gauge length must be measured with the interference absolute method. 量块检测过程中,高于二等和K级的量块工作长度就必须借助绝对测量。利用条纹法、二维FFT法和莫尔条纹法可以准确得到干涉条纹小数部分。
The authors designed a kind of improved control system based on the theoretical relation among the initial gauge length of sample, travel rate of testing machine transom, time and sample's real constant-strain rate. 根据试样初始标距长度、试验机横梁移动速度、试样真实恒应变速率和时间的理论关系式,设计了改进的控制系统。
