摘要
应用静电技术及电镜样品制备技术，研制了静电采样仪，并对其主要性能进行了测定，推荐了采样仪的电参数及采样时间．试验结果证明，应用静电采样仪能直接在现场进行焊接气溶胶粒子的采样，采样后不必经中间处理即可在电镜下进行观察分析．此项技术为研究焊接气溶胶粒子的形貌、粒径尺寸、化学成分和结构提供了有力手段．
Electrostatic sampling apparatus is developed by using of electrostatic technique and electron microsocope sample making technique. The main properties of the apparatus are determined and its electric parameters and its sampling time are recommended. Spot test proves that welding aerosols can be directly sampled. Samples can be directly observed under electron microscope without any furture process. This technique is very powerful in studying the shape size, chemical composition and structure of welding aerosols.
