摘      要：In this note the differential expressions of divergence,curl,and gradient are derivedbased on one common *** of them involves the limiting value of a differentialquantity per nuit *** taking advantage of some differential relations of the unitvectors weighted by the metric coefficients,the full expression of these three quantities invector analysis can be readily derivde.
