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.
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。

Results:The results were demonstrated by three-dimensional differential diagram of convolution spectra and match comparison diagram of correlation coefficients.
结果：用三维褶合光谱差谱和二维相关系数图谱显示鉴别结果，令人满意。

An important case is the linear homogeneous second-order differential equation with constant coefficients.
