if(hu>=0.81*hz*pow((hz/gg),0.72)) cd=0.611*pow(((hu-gg)/(hu+15*gg)),0.072)；
else cd=0.611*pow(((hu-gg)/(hu+15*gg)),0.072)*pow((hu-hz),0.700)*pow(((0.32*pow((0.81*hz*pow((hz/gg),0.720)-hu),0.700)+pow((hu-hz),0.700)),-1.00);

这两句错在哪了呢，显示的是error C2143: syntax error : missing ')' before ';'
                        error C2198: 'pow' : too few actual parameters

在';'前加一个 ')'就ok了，
