文章介绍了塑料格栅的两种拉伸试验方法,并对13组格栅样品进行了比对试验,通过显著性检验,证明了两种方法的有效性。两种试验方法得出的结果相关性很差,不能进行互相换算。同时,对试验的预张提出了要求。
Two kinds of tensile test methods for plastic grids are introduced in this paper. The comparative tests of 13 grid samples are carried out. The significance tests show that the two methods are effective. The correlation between the results of the two test methods is poor and can not be scaled to each other. At the same time, pre-test the requirements put forward.
