USEOFTHELIGHTMICROSCOPE
USE OF THE LIGHT MICROSCOPEEach time the microscope is to be used it should be set up correctly to give a good image. Most often users forget to adjust the iris diaphragm and focus the condenser to give its optimum performance, this could result in objects in the preparation being undetected.There are many microscope set up procedures for specific functionality but the most versatile for general use is ‘Critical Illu......阅读全文

伽马探测器GammaRay－Detectors介绍（一）
当超高能的伽马射线猛烈撞击地球大气层时，它们会引发粒子雨，并释放出一种昏暗的蓝光。利用这种光，天文学家可以追踪罕见的伽马射线（每平方米的大气每月只会发生几次撞击）直至它们的源头——宇宙中的一些剧烈事件，例如特大质量黑洞。伽马射线是原子核能级跃迁蜕变时释放出的射线，是波长短于0.2埃的电磁波。伽马射线
