![[Translate to chinese:] These images show the microstructure of a hard metal with 10% cobalt which is used for heavy-duty tools. The large increase in magnification of the right image (compared to the left) has a risk of being outside the useful range or, in other words, empty magnification.](/fileadmin/_processed_/d/b/csm_Microstructure_of_a_hard_metal_which_is_used_for_heavy-duty_tools_69233d4576.jpg "[Translate to chinese:] Microstructure of a hard metal with 10% cobalt which is used for heavy-duty tools.")
当心“无效”放大率
在一个最简化的情况，光学显微镜由一个靠近标本的透镜（物镜）和一个靠近眼睛的透镜（目镜）组成。显微镜放大率是两个显微镜透镜系数的乘积。比如，40倍物镜和10倍目镜可以得到400倍放大率。

什么是膜片钳技术？
离子通道的生理学一直是神经科学家感兴趣的一个重要话题。诞生于1970年代的膜片钳技术开启了电生理学家的新时代。它不仅可以对整个细胞进行高分辨率电流记录，还可以对切下的细胞膜片进行高分辨率电流记录。甚至可以研究单通道事件。然而，由于需要复杂且高灵敏的设备，广泛的生物学背景和高水平的实验技能，电生理学仍然是最具挑战性的实验室方法之一。
