我们无损检测工作者,都注意检查部件材质的好坏,要把不能用的部件挑出来,以免使用中发生意外事故,我们的激光全息也参与了一些这种工作。但是,对无损检测来说,这毕竟是不完全的,因为材质的好坏,有缺陷与否,对所构成部件能否使用固然有直接的影响,然而材质的缺陷与部件的使用价直,决不是一种简单的关系,在很多情况下,明知部件存在有某些某种缺陷,但是使用时却不会发生危险,若一发现材质
Our non-destructive testing workers pay attention to inspecting the quality of the parts, pick out the parts that can not be used, so as to avoid accidents in use. Our laser hologram is also involved in some such work. However, non-destructive testing, after all, is incomplete, because the material is good or bad, defective or not, the composition of the components can have a direct impact, but the material defects and the use of components straight, By no means is a simple relationship, in many cases, knowing that there are some defects some parts, but when used without danger, if a found material
