An efficiency formula for non - uniformity of load distribution the longitudinal direction of pile groups and a total lateral bearing capacity formula of n piles are set up 研究得出了計算縱向受荷排樁中各樁水平承載力不均勻分配效率系數公式和n根樁的總水平承載力公式。
The conversion efficiency formula of the flat wave for second - harmonic generation was deduced in detail . and that of the gaussian wave for second - harmonic generation also was given in the small signal deliver 詳細推導了平面二次諧波的倍頻轉換效率公式,介紹了小信號近似下高斯光束的倍頻轉換效率公式。
By a method for comparing , the conversion efficiency formula of the gaussian wave for second - harmonic generation ( cefgshg ) in general circumstances , which toke accounts of walk - off effect and self - focus effect together , was attained 通過類比的方法給出了一般情況下,同時考慮走離效應和自聚焦效應時的高斯光束倍頻轉換效率公式。
For multi - dimension acousto - electro - optical effect , the momentum mismatch is solely replaced by mismatch caused by electric field . based on this , one - dimension acousto - electro - optical coupled wave equation and multi - dimension acousto - electro - optical coupled wave equation are founded and their diffractive efficiency formulas are also deduced respectively 通過對聲光互作用耦合波方程中的動量失配進行修正,分別得到了一維反常聲電光布拉格衍射的耦合波方程以及多維聲電光效應耦合波方程的表達式,并進一步得到了相應的衍射效率的計算公式。
