Abstract:The interacting boson model with the boson effective interaction has been used to studythe nuclear spectra. In this paper,the E2 transition rates for t11ree four-boson nuclei are calculated bythe boson configuration-mixing wave functions that are obtained

Abstract:For polydiacetylene toluene sulfonate (PDA-TS), a quantum approach for calculating the oscillator strength between ground and the lowest lying excited states is presented, and the Stark shift of exciton is calculated, and the mechanism governing the nonli

Abstract:使用张邦维所提出的键参数函数和尺寸因素理论方法，对５６种金属基体二元合金的固溶度进行系统的研究，发现分隔每个基体金属可溶与不溶元素的定量方程式是一抛物线或椭圆，理论预言的总准确率对抛物线和椭圆规律分别为８７．２％和９０．３％，表明，这种对固溶度的理论研究，无论是系统性还是理论结果与实验数据符合程度都是文献中所未有过的。
