摘要
由于常用的光学测量方法的限制,研究气流中微小雾滴问题时,依据微粒在气流中响应时间极短这一特征,可以采用捕捉采样,在电子显微镜下拍照,获得其零径及尺寸分布。
Due to the time constant of mist droplet is very small, electron microscope can be used to measure the size and its distributionof mist on the sample catcher. For example, one is the size measurement of cigarette and incense fog for LDV seeding, another is the performance test for oil fog separation.
