On the Time Rate of Change of Circulation

[摘要] In this short note we have discussed the relations between dC/dt and ∂C/∂t, where C is defined as follows: C=∫s(udx+vdy+wdz).For the purpose of numerical calculations the expressions for dC/dt and ∂C/∂t are given in the form of line integrals but for the physical concepts they are given by surface integrals.
