This is equivalent to an angular distribution of constituent plane waves. 這等價(jià)于各種成分的平面波的角分布。
The influence of electrons and relativistic effects on the cross section, angular distribution, and spin polarization parameters of photoelectrons is studied in detail. 我們計算入射光子能量大于的游離閾而小于的游離閾時(shí)的光游離截面積，以及光電子角分布參數和自旋極化參數等物理量。
The irradiance of solar energy impinging on the top of the atmosphere has a meridional distribution. 投射到大氣頂部的太陽(yáng)輻照度只有經(jīng)向分布。
