| 作者姓名： | 高世桥 卢文达 |
| 摘 要： | In this paper, an appr cimate method is established to solve the couple problem between different harmonic waves in terms of the heeds of nonsymmetric imperfections of cooling tower. By means of this method, the frequencies and response of rotational shell with local geometric imperfections are analysed and calculated. |
