mean particle diameter meaning in Chinese

平均粒度直径
平均粒径
平均粒子直径

The addition and amount of mmt could not apparently affect the mean particle diameters of pvc / mmt nanocomposite latex
进一步对所制复合材料的乳胶粒径、分子量、力学性能及热性能进行了测试。
The size distribution of composite latex particles is similar to that of polyacrylate / caco3 latex . their mean particle diameters gradually decrease with amount of polyacrylate / caco3 latex and caco3 / monomers increasing , but the mean particle diameters of the composite latex are much bigger than particle diameters of caco3 latex . molecular weight of pvc composite resin was determined by viscometer
结果表明：复合胶乳呈现与种子粒径相近的单峰分布，其平均粒径随聚丙烯酸酯caco _ 3种子胶乳中caco _ 3加入量的增加而逐渐减小，但复合乳胶粒径比种子粒径要大很多；用粘度法测定了复合树脂中pvc的粘均分子量。
The general characteristics of the grain - size distribution of different sedimentary facies , es pecially the variations of the parameters mz ( mean particle diameter ) and o ( standard deviation ) clearly show that the fluvio - lacustrine facies and palaeosols usually become finer in particles and worse in sorting than the aeolian sands
该剖面不同沉积相粒度的一般分布特征尤其是粒度参数? mz 、的变化明显表现出，河湖相或古土壤通常要较风成砂颗粒细化，分选相对较差。
