Standard test method for field pull testing of an in - place exterior insulation and finish system clad wall assembly 外部绝缘和精整系统包壁组件中的现场拉伸测试的标准试验方法
Junit reinitializes all fields for each and every method executed , so pulling test data out of fields and into local variables can speed things up significantly when the fields aren t used by every method in the test class Junit会重新初始化每个执行方法的全部字段,所以如果不是测试类的每个方法都用的字段,那么把测试数据从字段中拿出来放在本地变量中,可以显著提高速度。

Through the strong pulling tests of four kinds of synthetic fiber filter cloth , the mechanical performance index of the filter cloth in dry and wet conditions were measured , the influence of various pulling speeds on the fracture strength and the fracture tensile rate of the filter cloth was derived . it was concluded that the stress of the filter cloth could relax when it was beyond the yield point 通过4种合成纤维滤布的强力拉伸试验,测得了滤布在干、湿两种状态下的力学性能指标,得出了不同拉伸速度对滤布断裂强度和断裂伸长率的影响,同时指出当滤布的应力超过屈服点时,会出现应力松驰现象。
