partial derivative

基本解释

That is not a partial derivative, OK?
这可不是偏导数哈？
OK, so that's the definition of a partial derivative.
好的，那就是偏导数的定义。
That was this symbolic vector operator in which the components are the partial derivative operators.
这个是符号化的向量算子,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.
我们还发现,这个偏微分出现在了，内能的偏微分,定义式中，它也就是热容。

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，对于一个恒定体积的过程，我们可以写出,等于偏u偏T，V不变，加上偏u偏V，T不变。

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的二阶导数,混合导数，对T偏微分,再对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.

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

偏导数
The partial derivative is defined based on the convergence in probability measure in the probability measure space.
首先,在概率测度空间上,利用依概率测度收敛,定义了多随机变量函数的偏导数。

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节根据Taylor展开，将空间一阶偏导数用2N个对称点的函数值的线性组合近似，并根据线性代数理论推导了确定系数的公式。
