查询词典 symmetry

During the infiltration process of indirect subsurface drip irrigation, the ponded water depth changed from zero to a constant and accelerated the water movement in the vertical direction, which reduced the discrepancy of wetted distance in lateral direction and vertical direction, while the changed water depth had small influence on the wetting front movement in vertical direction to upward and downward. The shape of wetted soil zone was spheroid, and its symmetry axis lied near the bottom of the water conducting device.

间接地下滴灌灌水过程中，从零开始逐渐增大并趋于稳定的积水深度加速了水分在垂直方向的运移，缩小了横向湿润距离和垂向湿润距离之间的差异，但变化的积水深度对湿润锋在垂直方向向上和向下的运移速率影响不大，使湿润体形状表现为扁率不断减小的椭球体，且椭球体对称轴分布在靠近导水装置底部的位置。

Symmetry helps, but the temptation to cheat will be too great if rival firms cannot monitor each other's behaviour and respond quickly if one of them reneges.

公司实力相当有助于维持这种价格平衡，但是如果对手公司无法左右其他公司的行为，又无法对违约公司做出及时反应，这种情况下，违背约定带来的好处似乎更令人心动。

The symmetry in the left and right wheel path bias revels that the deviation is the result of dynamic vehicle roll.

左右两边的对称显示出偏差是动态汽车滚动的结果。

Similar to Pt/Co multilayers, the PMA in the Co-Pt alloy film originates from the reduction of symmetry in the interface between magnetic and non-magnetic layers. Addition of a small amount of Ni in the Co-Pt alloy film leads to an obvious decrease in the Curie temperature, but the decreases in Kerr rotaion and PMA are quite limited. Furthermore, it promotes the growth of grains and roughens the film surface and thus enhances the coercivity of the film, which are of advantage for short-wavelength MO recording.

在Co-Pt合金薄膜中加入少量的Ni可促进晶粒生长、增加表面粗糙度、提高矫顽力，并且在不明显减弱垂直磁各向异性和极克尔角的情况下，能有效地降低居里温度，有利于短波长高密度磁光存储。
