微分式 [数] differential expression
- 好,让我们回到这个微分式。
OK, and now we return to this differential. - 好,我们现在得到了,两个微分式中的一个,它等于与系统密切相关的一个量。
So now I have my first of my two slopes, in terms of something that's related to my system the heat capacity of the system. - 通过构建区域微元量(元素)的一元微分式,可把一些特殊重积分直接化为通常的定积分,极大地减少了计算量。
By means of constructing first order differential forms of volume element, some special multiple integrals can be come down to ordinary single integrals. This approach greatly reduces the computation.
