常見(jiàn)例句雙語(yǔ)例句We study these variational problems respectively by the variational method and the theory of variable exponent spaces.我們主要運(yùn)用變分法和變指數(shù)空間的理論作爲(wèi)工具研究了這幾個(gè)問(wèn)題。The expression of ground energy is given by means of variational method, and the condition of formation of photon pairs discussed.然後利用變分法求得了超導(dǎo)波態(tài)系統(tǒng)的基態(tài)能量表達(dá)式，竝討論了光子對(duì)的形成條件。Some end value condition derived by variational method in accordance with the least energy loss principle and their mechanical background are also dealt with.同時(shí)從能量最小原理出發(fā)，用變分的方法推導(dǎo)出幾種耑值條件，說(shuō)明它們的力學(xué)背景。 返回 variational method
