Examples

The variational parameter multiplying each coordinate is called a scale factor .
每個(gè)坐標(biāo)所乘的變分參數(shù)叫定標(biāo)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(yùn)動(dòng)方程是一組分段函數(shù)，為了表達(dá)fw線型的連續(xù)性，必須考慮分段點(diǎn)的銜接問(wèn)題，統(tǒng)一x 、 y 、 z三維坐標(biāo)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(kù)侖相互作用，并且計(jì)入因相同粒子不可識(shí)別所帶來(lái)的交換項(xiàng)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(gè)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(guò)復(fù)雜的數(shù)學(xué)推導(dǎo)得到帶電激子體系能量的數(shù)學(xué)表達(dá)式，對(duì)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(jìn)而計(jì)算出體系的束縛能和相關(guān)能隨阱寬的變化。
