【Abstract】 Based on the physical thoughts of d’Alembert’s method,the features of the one-dimension string vibrating equations with a special finite boundary are analyzed and Fourier’s series solution is deduced.The results are important to better understand the guiding role of physical thoughts for solving the mathematical physical equations and the separate variables method。更多还原
