分析了大应变测量的非线性问题及解决方法，介绍了应用双稳流电源电路原理研制的超大应变测量仪，它能完全线性地把应变计电阻变化转换成电压输出，再由４位半数字表显示出应变值的大小，该仪器测值准确、使用方便。
The nonlinear problem of large strain measurement and its solution are analyzed. The large strain gauge developed by using the principle of bistable power supply circuit is introduced. The strain gauge can convert the resistance change of strain gauge into the voltage output completely linearly, Table shows the size of the strain value, the instrument measured accurately, easy to use.
