The second-order perturbation formulas of the g factors and hyperfine structure constants for the lowest Kramers doublet Γ〓 of a 3d〓 ion under various octahedral symmetries (cubic, tetragonal, trigonal and rhombic) are established.

在较统一的理论模型和计算方法上建立了在各种对称性（立方、四角、三角和斜方）的八面体晶场中3d〓离子最低Kramers双重态Γ〓的g和A因子的二阶微扰公式，其中包含了前人通常忽略的组态相互作用、共价效应以及低对称畸变对自旋哈密顿参量的贡献。

He sighed wearily as he walked slowly back across the flagged quadrangles in the Temple to his own solitary chambers.

他一边儿厌倦地叹息，一边儿慢慢地穿过圣殿的四角方方的铺着石板的院子，走回他自己的冷落寂寞的事务所去。

The city wall four jiao have four design exquisite watchtowers.

城墙的四角有四座设计精巧的角楼。

Finally, far away to the east, Vincennes, and its seven quadrangular towers to the south, Bic阾re and its pointed turrets

最后，远处东边是樊尚林苑及其七座四角塔楼；南边是比塞特及其尖顶小塔；注意，注意力集中

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
