As long as those economies remain relatively undynamic, the most talented ( especially English-speakers) will use their wits to look for work elsewhere. 只要这些国家的经济相对稳定,最具技能的人们就将发挥其才智到其它地方寻求财路,特别是那些讲英语的人。
A static village community and a completely undynamic type of agriculture; static feudal societies. 停滞不前的村落社会和完全没有活力的农业;停滞不前的封建社会。
A quantum system with time-dependent Hamiltonian which transports slowly will acquire an undynamic phase factor exp { I γ n ( t)} factor during evolution in addition to a dynamic phase factor. 一个作循环周期缓慢演变的含时Hamiltonian量子系统,在演变过程中波函数除了熟悉的动力学相因子外,还附加一个非动力学性质相因子exp{iγn(t)}。
The primary productions in this paper are as follows: ( 1) Berry's phase is the integrable case of undynamic phase, and it has geometric property; 本文中作者的主要成果体现在下面两个方面:(1)分析了Berry几何相属于非动力学相的可积情况,且它具有几何属性;
