The management of west agricultural water should follow the principle of circulation regeneration,coordinative symbiosis and sustainable self-generation.
对西部农业水的治理应遵循循环再生原则、协调共生原则和持续自生原则:调整农业结构,增强水资源的再生功能;合理开发利用水资源,增强共生功能;加强生态环境保护与管理,提高水资源自我调节功能,实现持续自生。
As an important consequence of the spin splitting,the persistent spin current is not simply proportional to the charge current.
在介观半导体环中,自旋-轨道耦合的存在直接影响持续自旋流的流动。
It is this spin Berry phase that induces a persistent spin current.
此前人们已经知道,在有磁通穿过的介观小环中,绕环运动的电子会产生一附加的Berry相位而导致持续电流;同样地,在仅有自旋轨道耦合的体系中,电子绕环运动也应当会产生附加的自旋Berry相位,进而驱动持续自旋流。
In the normal region,the incontrovertible definition is used to calculate the persistent spin current,and the calculation formula is also discretized.
在正常区域,用没有争议的定义来计算持续的自旋流,将计算持续自旋流的公式也进行离散化。
