band quantum number 中文意思是什麼
band quantum number
解釋
譜帶量子數-
2. in this paper, the continuity of the wavefunction and of its derivative divided by the band - mass can be satisfied and the number of the terms is small when calculating the energies of the single electron in a square quantum wire with finite barriers, then this wavefunction can also be selected as the envelope function in studying the impurity states and the excitons in the square quantum wires with finite barriers
2 .由於本文所取波函數滿足波函數的連續性條件和粒子流的守恆條件，並且計算有限深方形量子線中單電子的能量時需要展開的項數較少，故此波函數也可選為有限深方形量子線中雜質態、激子等問題的包絡函數。 -
The first two kinds of wavefunctions are simple formally, but there must be error of the numerical values of some physical magnitudes because there is a trouble with the continuity of the function and of its derivative divided by the band - mass at the boundaries. though the third kind of wavefunction can satisfy the continuity of the function and of its derivative divided by the band - mass, the number of the terms is so large that it is difficult to calculate the physical magnitudes in the single quantum wire
前兩種波函數形式比較簡單，但由於在邊界處波函數的河北師范大學碩士學位論文連續性條件和粒子流的守恆條件存在問題，這必將對某些物理量的計算產生影響;第三種波函數在邊界處滿足波函數的連續性條件和粒子流的守恆條件，但是對于單量子線需要展開的項數很多，計算量太大。 -
[ 5 ] expressed the wavefunction in terms of a two - dimensional fourier series. this form can satisfy the continuity of the function and of its derivative divided by the band - mass. but the number of the terms is so large that it is difficult to calculate the physical magnitudes in the single quantum wire
1996年， s . gangopadhyay等人將波函數用二維傅立葉級數展開，這種取法滿足波函數的連續性條件及粒子流（ 1 / m ~ * ） ' （ x ， y ）的守恆條件，但是當考查單量子線時，需要展開的項數很多，計算量很大。
