查询词典 surface active agent

G. it is up to 80 eV when the cluster plane is parallel to the surface. In addition, the impact induced adsorption of C〓 cages was studied in detail. After impacting, the normal incident C〓 was found to move laterally on the surface due to the anisotropic interaction between the dimerized surface and the cage. Finally, it resided on the top of a dimmer or in the trough, which are the energy favored adsorption sites.

在能量为10-20eV的C〓富勒烯表面吸附动力学过程的研究中，我们还发现表面结构的不对称性会引起团簇-表面相互作用的各向异性，从而导致入射团簇在表面上有与入射方向垂直的的横向运动，最后吸附在两个二聚体的中心点和谷点，这两个位置是能量最低的的吸附组态。

Wettability depends on one specific property of the surface: Surface Energy , often referred to as Surface Tension, which is measured in mN/m or dynes/cm.

润湿性依赖于某一特定财产的表面：表面能量，通常称为表面张力，这是衡量分钟/ m或戴恩斯/厘米。

According to the 137Cs concentration distribution along a typical profile A-1, the sediment accumulation rate and the natural surface soil erosion rate are respectively 16.6t/km^2a and 45.95t/km^2a, which shows that about 63.88% of the eroded surface soil is removed by way of underground loss. The relative contribution ratio of surface soil loss and underground soil loss are respectively 70.13% and 29.87%. By comparison to the utmost soil formation rate 13.51t/km^2a in Maolan, the risk of soil erosion in the Engineering Monument grass-covered depression is higher.
