surface of equal density
解釋
等密度面-
Michell computed that a body 500 times the radius of the sun and of the same density would have at its surface an escape velocity equal to the speed of light, and therefore would be invisible
米切爾計算一個500倍太陽半徑而且具有相同密度的物體就會具有它的表面逃逸速度等於光速，而因此不可見。 -
Abstract : the effect of correction of self - consistent potential on electronic structure in simple cubic nanocrystal particles is calculated by means of the green ' s function method in the tight - binding approximation, taking only the nearest neighbor matrix elements into account. the numerical results show that the electronic energy spectrum is shifted, the chemical potential is not equal to the atomic energy level, the electronic density at each lattice point is changed, and the variation of electronic density at surface lattice point is the largest
文摘:在緊束縛近似下，只計及最近鄰的矩陣元，採用格林函數計算了自洽勢修正對簡立方納米晶體顆粒的電子結構的影響，發現電子能譜發生了移動，化學勢不等於格點原子能級，各格點的電子密度也發生了變化，其中以表面格點的電子密度變化最大。
