Something I can measure and I can tabulate, and when I turn my dT knob, I know what´s going to happen to the enthalpy.
我可以测量它并制成表格,当我转动 dT 旋钮,我就知道焓的变化了。
Now I can easily get dT / d beta.
现在我可以很简单的得到dT/dβ
And now I have a relation between df and dt.
现在得到了df和dt的关系。
So that´s d/dt of h.
所以是对h进行d/dt运算。
dy x dt That tells us dx is x prime of t dt.
是y’dt,dy,becomes,y,prime,of,t,dt。,是x,So,,we,know,x,is,x,of,t。,它告诉我们dx是x
