Therefore,the removal efficiencies of turbidity and particle count,as substitution indexes,were used to judge the control effect of BAC filter on Cryptosporidium and Giardia.
传统的贾第鞭毛虫和隐孢子虫(简称"两虫")检测方法存在诸多不足,为此选用浊度和颗粒数作为"两虫"的替代指标,以对浊度和颗粒物的去除率来衡量生物活性炭(BAC)滤池对"两虫"的控制效果。
3)  population density
粒数密度
1.
From experimental population density data of dexamethasone sodium phosphate, kinetics constants of size-independent and different empirical size-dependent growth rate models were gotten by the method of non-linear least-squares.
由实验得到的地塞米松磷酸钠晶体的粒数密度分布数据,采用非线性最小二乘法分别对与粒度相关和与粒度无关线性生长速率模型进行了参数估值,通过由各种模型得到的晶体生长速率的计算与实验值的比较,发现与粒度无关生长速率模型不仅计算过程简单且计算的精度也更好。
4)  population balance
粒数衡算
1.
The crystal size distribution(CSD) of products was analyzed with population balance, which set up the kinetics equation of crystallization of xylose from aqueous solutio
本文作为木糖生产新工艺的重要环节,研究了木糖连续冷却结晶过程,并根据结晶动力学的粒数衡算理论(Population Balance)及其连续稳态的动力学测定方法,探索了木糖的结晶动力学模型。
5)  Particle number

Aimed at the microbial safety of ozone/biological activated carbon(O3/BAC) process,through the pilot-scale and productive experiments,a systematic evaluation was carried out considering the aspects of pathogenic microorganisms,microbial population,turbidity,particle number and AOC.
针对臭氧/生物活性炭工艺在应用过程中可能存在的微生物安全性问题,通过中试和生产性试验从病原微生物、微生物群落、浊度和颗粒数、AOC等四个方面进行了系统评价。
6)  Number concentra-tion

参考词条
补充资料:粒子数比
分子式:
分子量:
CAS号:

性质:符号为R,粒子i与粒子k的粒子数比定义为粒子i的粒子数Ni除以粒子k的粒子数Nk。粒子数比为无量纲量。当粒子本身就是物质的量的基本单元时,粒子数比等于物质的量比。
