Column in the same horizontal line, the high speed rail board installation is very easy, convenient, otherwise there will be a phenomenon of screw dislocation, can not be installed.
立柱在同一水平线后,高速护栏板的安装也就非常容易、便捷了,否则会出现螺丝错位的现象,无法安装。
2
The image force acting on the piezoelectric screw dislocation and the generalized stress on the surface of rigid line are calculated.
导出了作用在位错上的像力和刚性线夹杂表面剪应力和电位移的解析表达式。
3
The variation of screw dislocation forces for correlative material parameters and different radians of crack or rigid line is discussed particularly.
