| 两者的原理都是一样的。 The two principles are the same. 安检X光机的用法就是将行李放入物品扫描X光机内，待检测完毕后，旅客再拿回自己的行李离开。对物品进行过机检查用的X光机是利用X射线穿过物体而获得X影像，通过计算机处理显示在电脑屏幕上，用以辨认图像、评估物件安全性。原理虽然与医院做人体X检查类似，但安检X光机的剂量，应该比人体照射的X光量要少。因为安检的X光机只需要看到大概，看出是什么形状的东西就可以了。而医用X光机需要把人体看得很清楚，因此辐射剂量更大。 The use of the security X-ray machine is to put the luggage into the item scanning X-ray machine, and after the inspection is completed, the passenger will take back his luggage and leave. The X-ray machine used for checking objects is to obtain X-ray images by X-ray passing through objects, which are fuzhou.89ix.comhaikou.89ix.com shanghai.89ix.comtianjin.89ix.comchongqing.89ix.comxin.75ix.comdisplayed on the computer screen through computer processing for identifying images and evaluating the security of objects. Although the principle is similar to that of human X-ray examination in hospitals, the dosage of X-ray machine for security inspection should be less than that of human body irradiation. Because the security X-ray machine only needs to see roughly what shape it is. Medical X-ray machines need to see the human body clearly, so the radiation dose is higher. |
