我们试制了一种特殊的专用卡尺。使用这种卡尺,可以不经过计算,就能直接在卡尺上读出试样的延伸率。这无疑会给测试工作带来方便,使工作效率得以提高。现将这方面的情况介绍如下。1.问题的提出通常获得试样延伸率的方法是:(1)确定试样的标距 L_0。如图1所示。
We tried out a special kind of special caliper. With this type of caliper, the elongation of the specimen can be read directly on the caliper without calculation. This will undoubtedly bring convenience to the test work, so that work efficiency can be improved. Now the situation in this regard are as follows. 1. The question is raised. Usually get the sample elongation method is: (1) to determine the sample gauge L_0. As shown in Figure 1.
