Simulating of depth analysis of atomprobe along vertical direction to grain boundary 模拟原子探针垂直于晶界方向上的深度分析
Formulas for vertical distribution of grain composition of suspended sediment in river 悬移质泥沙级配沿垂线分布公式探求
The smaller the dust grain size, the higher the vertical displacement of dust grain due to electrostatic levitation on the same environmental condition. 随着粒径的减少,月尘颗粒的最大浮扬高度不断增加。
Preliminary Analysis on Vertical Distribution Of Leaves Grain And Light Of Colony Canopy Of Soybean 大豆群体冠层叶粒与光照垂直分布规律的初步分析
These results are available to calculate the critical sand transportation velocity of no silting in vertical well bore of low sand grain concentration and can be referred to solve the sand transportation difficulties of vertical well bore in other areas. 研究成果可用于计算垂直井筒内低浓度砂粒无淤塞的最低携砂流速,对于解决其他地质区块和微小颗粒的垂直井筒携砂问题具有借鉴意义。
