variationally中文什么意思
例句與用法
- in the effective mass approximation, using the two-dimensional equivalent potential model and a simple two-parameter wave function, we calculate variationally the ground state binding energy and correlation energy of positively and negatively charged excitons in finite deep gaas-al0.33ga0.67as quantum wells . the results show fair agreement with the previous experimental results
在有效質(zhì)量近似下，我們采用二維等效勢(shì)模型，并且選取了數(shù)學(xué)形式簡(jiǎn)單、物理意義明確的兩參數(shù)變分波函數(shù)，利用變分法數(shù)值計(jì)算了有限深gaas?al_(0.33)ga_(0.67)as量子阱中帶電激子的基態(tài)束縛能及相關(guān)能，所得結(jié)果與實(shí)驗(yàn)結(jié)果符合得很好。 - firstly, we calculate variationally the binding energy and correlation energy of excitons in finite deep gaas-al0.33ga0.67as quantum wells . in the calculation, we consider the effect of effective mass and dielectric constant mismatch in the two materials . the results we obtained are basically conformed to the ones obtained from the previous theory and experiment
首先，我們計(jì)算了有限深gaas-al_(0.33)ga_(0.67)as量子阱中激子的束縛能，其中考慮到了阱和壘兩種材料中電子和空穴的有效質(zhì)量以及介電常數(shù)的失配影響，我們計(jì)算得到的激子的束縛能及相關(guān)能與前人的理論結(jié)果和實(shí)驗(yàn)結(jié)果基本上相符合。
