An aerosol, natural or artificial is made to flow through a length of tubing, the aerosol particles diffuse to the walls . 让自然或人造气溶胶通过一段管道,气溶胶粒子就扩散到管臂上。
Aerosol particles affect visibility , climate , and our health and quality of life 气溶胶对大气能见度、气候变化以及人类健康等有重要影响。
It is now widely used in aerosol particle precipitation , ultrasonic atomization and ultrasonic detection 在超声除尘、超声雾化、超声检测等领域有广泛的应用。
The aerosol particles adhered on the surface might partially separate and resuspense under lashing of higher flow velocity 沈积的气溶胶粒子如果在更大流速冲击下,将发生反弹,部分气溶胶粒子从黏附表面上分离再次悬浮于流体中。
Abstract : in this paper it discusses the method of how to count the numbers of aerosol particles through using many - corridors discrete quantity gathering system 文摘:讨论了运用多道离散量数据采集系统,对微粒子进行检测的方法。
In addition , the spectrum characteristics , the optical thickness and the chemical composition of sand aerosol particles are also counted and analysed 并综合研究了沙尘气溶胶尺度谱特征、光学厚度和化学组分等变化特征,提出了若干结果。
At present , a group of researchers in asia is studying aerosol particles and their effects on the environment ? and they have plenty of dust to work with 现在亚洲有一批研究人员正在研究悬浮颗粒及其对环境的影响他们要研究的沙尘可多着呢!
The tube diameter had light relation with deposition rate under same volume flow amount , while the relation of deposition rate with aerosol particles size was relatively complicated 在相同体积流量下,沈积率与管径关系不大;而沈积率与气溶胶粒子大小之间的关系比较复杂。
