number concentration meaning in Chinese
计数浓度
Examples
- The number concentration of the activated cloud condensation nuclei ( ccn ) is described with the hypergeometric function
对降水物粒子引入分布谱函数，采用了与之相适应的微物理过程计算公式。 - Standard test method for wipe sampling of surfaces , indirect preparation , and analysis for asbestos structure number concentration by transmission electron microscopy
用透射电子显微镜检查法对石棉结构数密度进行表面的擦拭取样间接制备和分析的标准试验方法 - These were associated with sudden increases in measured number concentrations at high voltages , fluctuations in dma voltage and audible high - frequency sounds from the dma column
当高电压产生时，突然之间微粒数目之增多会与移动性分析器之电压及从移动性分析器产生之高频音有关。 - Besides its impact in the formation of the first raindrops by autoconversion , the prediction of cloud - droplet number concentration is especially important in cloud chemistry and radiative transfer
除了对初始自动转化形成降水的作用外，云滴数浓度的预报对云化学和辐射传输有特别重要的意义。 - Based on the dynamic frame of mm5 and reisner 2 explicit cloud scheme , a new double - moment microphysical scheme was developed , in which both the mixing ratios and number concentrations of cloud water , rain water , cloud ice , snow and graupel were predicted
从本质上说，该方案预报的仅仅是粒子的比含水量。在mm5动力框架内，在其中的reisner2方案基础上采用双变参数方案，增加了云水、雨水、雪和霰的数浓度预报方程。
