自旋温度 meaning in Chinese

spin temperature

A high spin temperature , for example , would indicate that a high fraction of atoms were aligned
例如，高自旋温度代表较高比例的原子，具有相同方向的自旋排列。
When the spin temperature returned to equilibrium with the radiation temperature , hydrogen was neither a net absorber nor a net emitter of 21 - centimeter photons
当自旋温度回归辐射温度而达到平衡，氢气便不再吸收，也不再发射21厘米光子。
Theory therefore indicates that the dark ages were defined by three distinct temperatures : the spin temperature ( a measure of the relative abundance of atoms with different spin states ) ; the ordinary , kinetic temperature ( a measure of the motions of the atoms ) ; and the radiation temperature ( a measure of the energy of the background photons )
因此理论上，黑暗年代是由三种截然不同的温度来定义：自旋温度（不同自旋状态原子相对数目的度量）、一般的动力温度（原子运动的度量）与辐射温度（背景光子能量的度量）。
