On choosing the variational wave function , we have considered the correlation between the confined and non - confined directions of the wires in order to make our results more exact . the whole paper is divided into two parts mainly 在選取變分波函數(shù)時(shí)考慮到了電子運(yùn)動(dòng)在量子線的限制方向與非限制方向的相關(guān)性,從而使得在寬阱時(shí)波函數(shù)和束縛能的精確度得到改進(jìn),全文主要由兩部分組成。
