Only small total volumes of liquid aerosols can be expected to reach the distal portions of the tracheobronchial tree . 只有很少一部分液状气溶胶可达到细末支气管。
The coatings are sprayed onto the components being analyzed by using aerosol cans or compressed-air spray guns . 涂料是用按钮喷雾罐或压缩气喷枪喷到所要分析的零件上去的。
The atmospheric aerosol affects our weather, our seeing and in some instances our well-being and even survival . 大气气溶胶影响天气,妨碍视线,有时也会影响我们的健康乃至生存。
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。
Clouds, rain, fog, snow, steam, and spray are commonly observed natural aerosols which are composed almost exclusively of water . 通常观察到的自然气溶胶有云、雨、雾、雪、蒸汽和水雾,它们几乎完全由水构成。
Sulphur, a ubiquitous element in the lower atmosphere was identified from the outset as a predominant component in the stratospheric aerosol . 在底层大气中处处存在的元素硫从一开始就被认为是平流层气溶胶的主要成分。
If an aerosol counter is used to monitor the concentration of particles in the emerging air, one finds that the concentration falls off with decreasing flow rate . 如果用一台气溶胶计数器检测射出气流中的粒子浓度,就会发现浓度随流速的降低而减少。
In an aerosol containing equal numbers of charged particles of both signs, the diffusive encounters for oppositely charged particles are more effective than for uncharged particles . 若气溶胶中含有等量正负带电粒子,那么正负带电粒子间的扩散碰撞比非带电粒子更容易实现。
