在应用扫描电镜观察小型线虫的正面结构时,常遇到标本装置、方位以及使其成为一条直线等技术上的困难。由于这些小型线虫的标本太小即使应用细镊也不易掌握,而且脱水后标本易碎,故要将虫体的前端安装在标准的平面样品台上往往失败。为此,本文 In the application of scanning electron microscopy to observe the front structure of small nematodes, often encounter the specimen device, orientation and making it a straight line and other technical difficulties. Because these small nematode specimens are too small to be applied even with fine tweezers, and the samples are easily broken after dehydration, it is often unsuccessful to mount the front end of a worm on a standard flat sample stage. To this end, this article
