粒子直径 meaning in English
particle diameter
Examples
- With methyl methacrylate the particle diameter increases linearly with conversion indicating particle aggregation .
采用甲基丙烯酸甲酯时，粒子直径随转化率呈直线增大，这就表明粒子发生了聚集。 - Average particle diameter
平均粒子直径 - Using the method in quantification metallography , the size of grain and hardening particles , volume percentage of inclusions and hardening particles are estimated according to samples
在解剖被检试样的基础上，运用定量金相学的分析方法，估算了被检部位的晶粒直径、夹杂物体积百分数、强化粒子直径及体积百分数。 - The simulation of debye theory and the experimental results can prove the results obtained . the relation of ripple frequency of the second rainbow with the diameter of particle is simulated by lorenz - mie theory , and used in particle sizing with high precision
利用lorenz mie理论模拟了均匀粒子二阶彩虹的ripple频率与粒子直径的关系，获得了ripple频率与直径的经验公式，并用于粒子直径的实验测量中，测量精度很高。 - The influence of the cloud droplet spectrum character and the spectrum growth and change is considered , which does not use a cut - off value for conversion from cloud water into rain water process . in the continuous coalescence equation , the particles fall velocity difference is not moved out from the integral , but is integrated in the equation as the function of diameter d to avoid the error of using particles average fall velocity . in the new scheme , generation rate of graupel due to the collection of snow by graupel and the collection of cloud ice by graupel are included
云中凝结核ccn的数浓度采用超几何函数表示；云水向雨水的自动转换过程采用grabowski ( 1999 )的公式，考虑了云滴谱的特征和发展变化对该过程的影响，而不是采用原方案给定阈值的方法描述该过程；对连续碰并方程不再将粒子落速差作为常量提出积分号外，而是直接作为粒子直径函数在积分号内求解，这样处理可以回避使用粒子群的平均落速带来的误差；增加了霰和雪、霰和冰晶的碰并微物理过程。
