本文研究了紊流条件下粗粒与细粒颗粒群间的相互作用,提出“粗粒效应”理论,包括三种作用机理:粗粒的载体作用,以漩涡微尺度λ_0为理论判据;粗粒的助凝作用,以颗粒雷诺数Re_p为理论判据;粗粒的中介作用,以裂解频率f_B为理论判据。
2) dellinger effect
粗捷效应
3) roughness effect
粗糙度效应
1.
25 mm cylinder height,the values of fRe increased quickly and oscillatingly when Re was larger than 150 due to the influence of the micro-size effect and the roughness effect on the cylinder surface and bottom of micro/mini cylinder group plates.
25mm实验段,由于微/小尺度效应、柱群底面及柱表面粗糙度效应等导致了其fRe在Re超过150后呈快速振荡增加。
4) particle size effect
粒径效应
1.
According to modeling of prototype,it was deduced that as long as the footings used in centrifugal and gravitational tests were different,the bearing capacity obtained in centrifugal tests was always larger than that obtained in gravitational tests,namely particle size effects always existed in centrifugal tests.
通过对原型的模拟结果进行总结,得出对于承载力试验只要离心试验中的模型基础宽度与重力场试验中的不同,离心模型试验结果总大于重力场试验结果,即离心试验中总是存在粒径效应问题。
5) Grain-size effect
粒度效应
1.
The acid effect、kinetics、salt effect and grain-size effect have been researched in order to learn the effect of different facts and master the rule of Cu、Pb releasing.

6) particle-size effects
粒度效应
1.
The difference of particlic s specifie surface area depending on particle size is not main factor affecting the particle-size effects.
结果表明,渭河沉积物吸附重金属的粒度效应决定于不同粒度沉积物的物质构成和颗粒表面特性,该效应是由沉积物对重金属的吸附速率的差别来体现的。
2.
Considering the particle-size effects of the sediment adsorbing heavy metals,the effects of heavy metal release from the sediment can be further strengthened.
考虑到沉积物吸附重金属的粒度效应,重金属释放的粒度效应会更加明显。
补充资料:粗粒
分子式:
CAS号:
性质:大气中颗粒物(或气溶胶)的粒径大于2μm(有时用大于2.5μm)的颗粒。粗粒模粒子属此。来源于自然界风沙和森林火灾产生的颗粒以及火山灰、海盐粒子等;人类活动的来源主要有工业生产和燃烧过程直接排放的颗粒物,它们绝大多数为一次颗粒物。一般被人的鼻咽部阻留,而进入下呼吸道,故对健康危害不甚严重。在涂料行业中粗粒的概念为漆膜表面有颗粒状杂物,影响漆膜的外观、光泽,漆膜表面不平滑。其原因是涂料的填料、颜料研磨不细,或储存时发生凝胶、变质返粗;涂漆场地有风砂、烟尘,或喷具不清洁等。
