From studying some kind of quite complex variational equation problems and applying the conclusion, we prove that the optimal control of new model is existent and characterize its structure.
The variational equation for general resonant cavities is used to derive the characteristic formula for the resonant frequency of the arbitrarily planar reso aators.
本文应用一般型谐振腔的变分方程,推导了平面型谐振腔谐振频率的特征方程。
In this paper, large amplitude variational equation of conical shallow thin shells is derived according to the principle of minimal action quantity.
