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:

本身內窺鏡能夠有用的去提高工作人員的檢查設備的效率，通過檢 查 部 件的一些內部的腐蝕，或者是鐵屑異物的狀態，去看一下，這里面是否含有著一些不好的質量缺陷，包括一些格紋或者是裂紋等等光束的照射到被檢測物體表面的時候觀察到，如果黑色或者是有一些亮色的線條，一定要放大一定的倍數，然后在線條周圍看一下是否會存在著一些不規則的邊緣，這樣的話就是一些裂紋。

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.

那么從另外一個方面來說，光束在照射的時候，如果觀察到有一些塊狀或者是點狀都不在一些光滑表面的時候，一定要放大倍數，看一下一些凹凸不平的情況是否是腐蝕的情況。光束應該以合適的角度進行照射，這樣的話，內窺鏡才能夠達到一定的檢測效果，需要觀察到與一些融化的金屬相連，沒有任何分明的界限，然后在凸起的時候能夠進行一個有效的焊接，這樣的話才是非常有效的一種方式。

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.

當光束進行一個平行照射的時候，就會發現一些凸起的部分背后有非常強烈的陰影，這個時候就需要改變光束的照射角度，看一下表面凸起的部分和周圍被檢測的部分，是否會存在著一些明顯的分界線，這樣也能夠判定出一些是否會出現起皮的情況。

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，如果發現被檢測的物體表面存在著一些比較規則的連續性的長線的話，就可以判定為拉線本身在光束照射的作用下，可以觀察到和周圍被檢查的問題，澀澤的一些光華是否會出現一些不平的情況，而這種情況也能夠起到一定的作用，并且去檢查這種設備出現了一些裂縫或者是一些其他的需要修補的問題。

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.
