So, these two are equal to each other as well which tells me that this derivative, Cp dH/dT constant pressure is Cp.
所以这两者也相等,这告诉我们在恒压下微分，等于。
It is the same thing as, in one variable calculus, when you take the anti-derivative of a function it is only defined up to adding the constant.
相当于在一元微积分中，取一个函数的不定积分，仅仅需要在结果后加一个常数。
That is, if we take the derivative G of delta G of mixing the partial derivative with respect to pressure, at constant temperature, of course, there's no explicit pressure dependence.
就是说，如果我们对,混合物的△,对压强求导，温度不变，当然，不是对压强的显函数。
Then we can take the derivative of that quantity, when we vary the temperature, holding the volume constant.
即恒定体积，改变温度，这里恒定温度下。
Note that any constant value may be added onto an indefinite integral without changing its derivative.
应注意的是，任何常数的值可以加入不定积分，而不改变它的导数。
As for the coal-bed gas reservoirs with constant pressure boundary, the log-log pressure curves are horizontal lines and the log-log pressure derivative curves are falling rapidly in the late stage.
对于存在定压边界煤层气藏，压力双对数曲线的晚期是水平直线段，压力导数双对数曲线的晚期都是急剧下掉的曲线。
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。
