而且在整个推导过程中，对于全导数和偏导数的概念没有分清楚。
And in the process of producing the concepts of the total derivative and the partial derivative are confused.
对摄动制导的弹道导弹而言，关机点偏导数和全导数计算及其校验是导弹诸元计算中的重要环节。
For the ballistic missile using perturbation guidance, the computation of partial derivative at shutdown point is very important for data calculation and validation.
现在可以看到，全微分里面的这些偏导数系数，都可以用一个变量表示出来。
Now you see how the total differential accounts for, somehow, all the partial derivatives that come as coefficients of the individual variables in these expressions.
其中关于均方全微分和均方方向导数的定理是多指标随机过程所特有的结论。
Four of them, i. e. the theorems on the mean-square total differential and mean-square directional derivative are special conclusions of the multiple parameter stochastic processes.
