| 9. | In the accretion disks in binary systems or at the centers of galaxies , particle collisions would produce an inflow of mass that is too small by many orders of magnitude to produce the brilliant luminosity of these disks
在双星系统或星系中心的吸积盘中，粒子的碰撞只会引起很少的质量向内流动，距离要产生可达到这些圆盘的耀眼亮度，还差了许多个数量级。 |
| 10. | However , the effect of high particle concentration on particle collision should be taken into account in the dense gas - solid two - phase flow . at the same time , gas turbulence should be taken into account in the simulation of gas flow in dense gas - solid two - phase flow
然而,在高颗粒浓度下颗粒碰撞对的确定需要考虑高颗粒浓度存在的影响,同时在高颗粒浓度流化床气固两相流动中,需要考虑气体粘性的作用。 |
