gfu meaning in Chinese

德国消费电子通信产品协会

3 . different test methods in determining those three fracture energy parameters arise one problem , that is whether gf . gfs and gfu are consistent as obtained from different measuring methods
由于测试混凝土三个断裂能参数采用的方法不同从而带来了一个问题，即不同的测试方法所得到的g _ f 、 g _ ( fs )和g _ ( fu )是否一致
Wherefore , other two energy - based fracture parameters are put forward : the stable fracture energy gfs , indicating the average energy dissipation during the crack stable propagation and the unstable fracture energy gfu , corresponding to the crack unstable fracture stage . wedge . ? splitting specimens are tested with a view to understanding those two parameters " size effect in terms of the initial crack length a0
本文提出两个能量型断裂参数即稳定断裂能g _ ( fs )和失稳断裂能g _ ( fu )分别表示裂缝稳定扩展和失稳扩展阶段的能量损耗，并采用楔入劈拉试件( ws )对这两个参数相对初始缝长_ 0的尺寸效应进行了分析。
