一个光学仪器(或产品)或组件,其内部结构和装配质量如何,有无隐患?有无改进的余地?特别是一具引进产品,其内部结构和光路有无独到之处,如果要拆开分析应从哪里入手?有无隐蔽的紧固件等等,由于产品内部都是不可见的,因此,很难判断。一、原理的阐述X射线是一种波长很短的电磁波,所以,具有很高的穿透能力。X射线的波长随电压的不同而不同,即:λ=f(V)。例如当电压为40～80kV时,λ为0.7～0.8A。利用X射线的这些性质,我们根据不同的分析对象,选择
An optical instrument (or product) or component, the internal structure and quality of the assembly, with or without hidden dangers? There is no room for improvement? Especially an introduction of the product, its internal structure and the optical path is unique, if you want to open Where to start the analysis? Whether the hidden fasteners and so on, because the product is not visible, it is difficult to judge. First, the principle of X-ray radiation is a very short wavelength of electromagnetic waves, therefore, has a high penetration ability. The wavelength of X-ray varies with voltage, ie, λ = f (V). For example, when the voltage is 40 ~ 80kV, λ is 0.7 ~ 0.8A. Taking advantage of these properties of X-rays, we choose according to different analytical objects
