And, in fact, what the equation will give us is the derivative of u with respect to t.
事实上,这个方程给出的是,u对t的偏导数。
Finally, some new viewpoints with respect to the conventional ideal cooling curve and cooling velocity below the martensitic t...
最后,对传统的理想冷却曲线及低温区的冷速问题提出了一些新的看法。
With respect to talented-personnel training and scientific research, the DMST is characterized by management of S&T and policy analysis.
科技管理系在人才培养和科研上以“科学技术管理与政策分析”为学科特色。
A It tells me that the partial of A with respect to T at constant V is minus S. Right?
他告诉我们,在恒定体积下对温度的微分等于负S,对吗?
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。
And the point is that the second derivative of A, with respect to V and T in this order is the same as the second derivative of a with respect to T and V in this order.
问题的关键在于A的二阶导数,对V和T以这样一个顺序求导,和对T和V以这样一个顺序,求导是一样的。
