意大利Metro－Com拉伸式松弛试验机的安装与调试

叙述了该试验机的工作原理及调试验收的５个指标：负荷误差的检定；夹头同轴度的检定；试验时试样长度保持恒稳定的检定，减荷时间与试样蠕变增量时间之比值的检定；试样在夹具内滑动量的检定。最后就该试验机的几处不足提出了看法。

The Installation and Debugging of Italian Metro-Com Tensile Type Relaxation Testing Machine

Introducing the testing machine's operation principle and 5 indexes of debugging acceptance, that is, 5 items should be examined such as the load error,chuck concentricity, sample length always in stable state during being tested, proportionality between the lightening load time and creepage increment time, the amount of the sample sliding in the champing device. In the end some disadvantages of the testing machine are put forward.
