生物实验中常用的光学仪器有放大镜、显微镜、解剖镜、投影仪、幻灯机等。保持这些光学仪器的清洁十分重要,这就要经常对其进行擦拭。但如果擦拭方法不正确,往往会损坏仪器或缩短其使用寿命。因此,在生物实验中教师和学生都必须掌握正确的擦拭方法。 通常情况下,上述光学仪器的机械部分可以用干净柔软的白纱布或绸布擦拭。例如显微 The commonly used optical instruments in biological experiments include a magnifying glass, a microscope, a dissecting microscope, a projector, a slide projector, and the like. It is very important to keep these optical instruments clean, which often wipe them. However, if the method is not correct, it can damage the instrument or shorten its service life. Therefore, both teachers and students must master the correct method of wiping in biological experiments. Normally, the mechanical parts of the optical instruments described above can be wiped with a clean soft white gauze or silk cloth. Such as microscopic
