应用离子蚀刻技术对截形叶螨进行显微解剖

The Application of Ion etching Technology in the Micro dissecting of Tetranychus truncatus Ehara

本文以截形叶螨为实验样品，经离子蚀刻后在扫描电镜下观察，清晰地显示了螨足、螨体解剖后的显微结构。足内各节的肌束等组织及螨体内的器官，结构清楚、真实，是１种较理想的显微解剖技术。

The speed of etching the sample was determined by controling the size ofion beam and voltage of two pole of ion beam,By the technigue of ion etching,themicroshape of the mite leg and the mite boby of the Tetranychus truncatus Ehara wasclearly displayed under Scaning Electronic Microscope(SEM).
