dispersion rate meaning in English

分散率
扩散率

At the same time , dispersion of different stokes number particles influenced by the ordered large - scale turbulent structures of the carrier gas phase was investigated . and the following " conclusion was drawn : particles of mediate stokes number mainly concentrated in the outer boundary region of large scale eddies , and they had the nignest dispersion rate ; particles or little stakes number mainly lay in the core region of the eddies , and they had the lest dispersion rate ; though particles of large stokes number distributed throughout the eddy structures
同时还模拟研究了不同stokes数颗粒在二维流场旋涡拟序结构作用下的运动扩散特性，详细描述了不同stokes数颗粒在流场中的空间分布规律，认为：中等stokes数颗粒集中于流场旋涡的外沿区域，在流场空间中的扩散率最高；小stokes数颗粒集中于流场系列旋涡的涡核区域，在流场空间中的扩散率最低；而大stokes数颗粒则遍布于流场旋涡涡核和涡外沿区域。
