1、从在运行试验机的专业技术看，试样如何保持在仪器底部是最重要的： 2、不同类型的试验机是要用不同的夹具的，如果在这一点上忽视了，则会导致试验机不能正常运行。

1, from the professional technology of running test machine, how to keep the specimen at the bottom of the tester is the most important: 2, different types of testing machines need to use different fixtures, if this is ignored, it will lead to the failure of the test machine to run normally.

3、如果更换夹具不但很难保持当前的位置的一致性，也容易损坏传感器。 4、而对于操作试验机的技术看，试验机是需要很大的力气才能完成，而这个是大多是男性才能完成的工作。

3, if the replacement of the fixture is not only difficult to maintain the consistency of the current position, it is also easy to damage the sensor. 4. And for the technology of the operation testing machine, the test machine needs a lot of strength to complete, and this is the work that most men can do.
