The variational parameter multiplying each coordinate is called a scale factor . 每個坐標所乘的變分參數(shù)叫定標因子。
In view of the shape character of fw core , we should analyse the fw contrail subsectionly . certainly , the demarcation points must be considered to link them up through uniting the 3 - d coordinate and making the central angle 9 to be variational parameter 由于fw運動方程是一組分段函數(shù),為了表達fw線型的連續(xù)性,必須考慮分段點的銜接問題,統(tǒng)一x 、 y 、 z三維坐標的參照系。
In this wave function , we consider the whole coulombic correlation among the particles , and the effect of the interchanged term caused by the same particles . where a and are the two variational parameters , and the parameters of ax and yx are determined by the two equations obtained from the variation of the energy of excitons ) 2 ) ,在波函數(shù)中,考慮到了粒子間的全部庫侖相互作用,并且計入因相同粒子不可識別所帶來的交換項的影響,和是變分參數(shù),而_ x和_ x由變分激子態(tài)的能量得到的兩個方程確定。
By the complicated mathematical calculating , we obtain the energy equation of charged excitons , from which we can determine the variational parameters a and , thus the complex energy of charged excitons can be calculated , and the binding energy and correlation energy of charged excitons can be obtained versus the quantum well width 通過復雜的數(shù)學推導得到帶電激子體系能量的數(shù)學表達式,對變分參數(shù)和變分可確定出變分參數(shù)和,從而得到體系能,進而計算出體系的束縛能和相關能隨阱寬的變化。
