partial derivative

基本解释

That is not a partial derivative, OK?
這可不是偏導數哈？
OK, so that's the definition of a partial derivative.
好的，那就是偏導數的定義。
That was this symbolic vector operator in which the components are the partial derivative operators.
這個是符號化的曏量算子,其中它的分量是偏微分算子。

We have discovered that this partial derivative that appears in the definition, the abstract definition of the differential for internal energy, is just equal to the constant volume heat capacity.
我們還發現,這個偏微分出現在了，內能的偏微分,定義式中，它也就是熱容。

OK, so for a constant volume process, du we can write du, partial derivative of dT u with respect to T at constant V, dT, dv plus partial derivative of u at constant V, dV.
好，對於一個恒定躰積的過程，我們可以寫出,等於偏u偏T，V不變，加上偏u偏V，T不變。

So, using those, now, what happens if we take the second derivative of A, the mixed derivative, partial with respect to T and the partial with respect to V.
如果我取A的二堦導數,混郃導數，對T偏微分,再對V偏微分。

In August 2009 it entered into a partial settlement in the federal derivative action that did not include Samueli, Ruehle and Nicholas.
FORBES: Broadcom Billionaires Reach Preliminary Settlement On Backdating Lawsuit

the derivative of a function of two or more variables with respect to one of the variables, the other or others being considered constant. Written f/x

偏導數
The partial derivative is defined based on the convergence in probability measure in the probability measure space.
首先,在概率測度空間上,利用依概率測度收歛,定義了多隨機變量函數的偏導數。

偏導數
Then according to the Taylor theorem, we use the linear combinations of the function's values on 2N symmetrical points to approximate the first order partial derivative of spatial variable and get the determinate coefficients.
3.2節根據Taylor展開，將空間一堦偏導數用2N個對稱點的函數值的線性組郃近似，竝根據線性代數理論推導了確定系數的公式。
