二阶微分方程复函数显式解唯一性证明

Second order differential equations using conventional solution method proved variable-fixed frame structure function is determined, in the initial value and the structure function parameter values to determine the conditions of the curve explicit solution of second order differential equations, and family reunification solution curve corresponds to only a curve. In the explicit solution of the second order differential equations, even more than the value of plus or minus square root phenomenon exists, but do not change the explicit solution of the differential equation only, because the explicit demultiplexing function is an even function.
