以势流理论为基础，本文用不可压流涡段所产生的扰动流场的线性叠加，计算涡分离流动的流场。

Based on the potential theory, a linearity combination of the disturbance flow field generated by the uncompressible vortex part was applied in the computation of separate vortex flow.

作者给出了计算波浪扰动力的公式，使得在时域中有航速船舶波浪扰动力的计算，可以用辐射势和入射波势来表示，而不须求解绕射势。

A proposed "D. Z. Z. formula" for computing wave exciting forces is presented, therefore the exciting forces in time-domain can be given without computing the diffraction potential.
