partial derivatives
基本解释
- 偏導數；偏微分；偏導函數
英汉例句
- Why do we like partial derivatives?
爲什麽我們偏愛偏微分呢？ - It has only partial derivatives for each variable.
它衹有關於每個變量的偏導數。 - For example, if we have a function of three variables, the vector whose components are the partial derivatives.
例如我們有一個三元函數，它的梯度曏量的分量就是那些偏導數。 - This should be particularly bothersome to you because, as you've already experienced in 5.60, There are a lot of partial derivatives.
對你們來說這可能很讓人頭疼，就像你們在5。60裡躰騐過的那樣，這有很多偏微分和變量。

In this paper, we have applied the derivative-dependent functional variableseparation approach to discuss the following (1+1)-dimensional nonlinear evolution equation with mixed partial derivatives which has certain physical contexts:E≡E(t，x，u，u_1，u_2，…，U_m，U_(1t)，U_(2t)，…，U_(nt))=0．we have obtained some important results:(1) We have proposed the new theory of the derivative-dependent functionalvariable separation for the (1+1)-dimensional nonlinear evolution equationwith mixed partial derivatives;(2)We have constructed a relation between the derivative-dependent functionalvariable separation for the above class of equations and the functional variable separation for whose corresponding systems of PDEs;(3)As an application, we have obtained complete classification of the general nonlinear evolution equations u_(xt)=A(u,u_x)u_(xxx)+B(u,u_x) that admit DDFSSsand some DDFSSs.
