不辐射的

In this thesis, the contribution of electric quadrupole (E2) and higher pole transitions to the opacity of hot and dense plasmas of element aurum is taken into account by using an average-atom model.

因此本文在有心力场单电子近似下，利用平均原子模型研究了电四极及更高阶跃迁对金元素的高温稠密等离子体辐射不透明度的贡献。

The radiation is emitted by unstable atomic nuclei as they attempt to become more stable..

不稳定的原子核在试图变得更稳定的过程中发射出辐射。

The story of the quantum revolution has been told so many times that it has become as ritualized as the stations of the cross. How Max Planck, faced with some curious observations about hot glowing objects, reluctantly proposed that light is sputtered out in packets — the quanta. How Albert Einstein , seeing deeper, realized that light must also travel that way, that its waves were also particles. How Bohr brought the graininess into the atom, with electrons hopping between orbits in quantum jumps. How Heisenberg, marooning himself on the bleak isle of Helgoland, saw that there were no orbits, that what happened inside atoms was different from anything that could be pictured by a human brain.

量子革命的故事已讲述过很多遍，就象讲述耶稣受难经过的画像一样已经仪式化，诸如：马克斯·普朗克面对炽热物体一些不寻常的观测数据，如何艰难地提出辐射是一单元一单元地射出的，这种最小的单元即能量子；爱因斯坦观察得更深刻一些，如何意识到光线也是这样运行的，光波也是粒子；玻尔如何利用量子跃迁过程中电子在轨道之间来回跳跃，来揭示原子的多微粒结构；海森堡自我流放到阴冷的赫尔戈兰岛上，如何观察到原子内部并没有轨道，其内部所发生的情况不同于人脑可想象出的任何情况。

Using simple boundary condition, the temperature gradient along the z direction is a constant while the generative internal heat is not considered.
