For the endoscope, this inspection technology has very significant significance and effect in the internal inspection of some industrial air tubes or compressors, and has been widely used. Some image processing systems and recorders of this product can carry out useful analysis on some inspection defect records anytime and anywhere, It can be used in some storage tanks or heat exchangers in petroleum refineries, and there is no need to disassemble the inspected equipment in the testing process, so it has a relatively high cost-effective and testing scheme. How can we determine whether there is any problem with the device during the use of the endoscope? The editor of endoscope equipment maintenance company tells you:

本身内窥镜能够有用的去提高工作人员的检查设备的效率，通过检 查 部 件的一些内部的腐蚀，或者是铁屑异物的状态，去看一下，这里面是否含有着一些不好的质量缺陷，包括一些格纹或者是裂纹等等光束的照射到被检测物体表面的时候观察到，如果黑色或者是有一些亮色的线条，一定要放大一定的倍数，然后在线条周围看一下是否会存在着一些不规则的边缘，这样的话就是一些裂纹。

The endoscope itself can be useful to improve the efficiency of the staff's inspection equipment. By checking the internal corrosion of some parts or the state of iron filings and foreign objects, we can see whether there are some bad quality defects, including some grid lines or cracks, which can be observed when the light beam irradiates the surface of the detected object, If there are black or some bright lines, be sure to enlarge them by a certain number of times, and then look around the lines to see if there are some irregular edges. In this case, there are some cracks.

那么从另外一个方面来说，光束在照射的时候，如果观察到有一些块状或者是点状都不在一些光滑表面的时候，一定要放大倍数，看一下一些凹凸不平的情况是否是腐蚀的情况。光束应该以合适的角度进行照射，这样的话，内窥镜才能够达到一定的检测效果，需要观察到与一些融化的金属相连，没有任何分明的界限，然后在凸起的时候能够进行一个有效的焊接，这样的话才是非常有效的一种方式。

On the other hand, if it is observed that some lumps or dots are not on some smooth surfaces when the beam is irradiated, it must be magnified to see whether some bumps are corrosion. The light beam should be irradiated at an appropriate angle. In this way, the endoscope can achieve a certain detection effect. It needs to be observed that it is connected with some molten metal without any clear boundary, and then an effective welding can be carried out when it is raised. In this way, it is a very effective way.

当光束进行一个平行照射的时候，就会发现一些凸起的部分背后有非常强烈的阴影，这个时候就需要改变光束的照射角度，看一下表面凸起的部分和周围被检测的部分，是否会存在着一些明显的分界线，这样也能够判定出一些是否会出现起皮的情况。

When the beam is irradiated in parallel, it will be found that there is a very strong shadow behind some convex parts. At this time, it is necessary to change the irradiation angle of the beam to see whether there will be some obvious boundaries between the convex parts on the surface and the surrounding detected parts, so as to determine whether there will be peeling.

在光束的照射下，如果发现被检测的物体表面存在着一些比较规则的连续性的长线的话，就可以判定为拉线本身在光束照射的作用下，可以观察到和周围被检查的问题，涩泽的一些光华是否会出现一些不平的情况，而这种情况也能够起到一定的作用，并且去检查这种设备出现了一些裂缝或者是一些其他的需要修补的问题。

Under the irradiation of the light beam, if it is found that there are some regular continuous long lines on the surface of the detected object, it can be determined that the cable itself can observe and check the problems around under the irradiation of the light beam, and whether some luster of astringent luster will show some uneven conditions, which can also play a certain role, And check that the equipment has some cracks or other problems that need to be repaired.
