| 摘 要： | 解析解一方面有其理论意义，另一方面可以作为标准解来验证各种数值解法及供计算传热学研究差分格式，网格生成等这用。文章对分析汽轮机空心转鼓式转子的不定常传热方程给出了其任意多个可能的解析解，其中一些与实际情况较为相近，除可作为标准解析，还可以供工程应用参考。

| Abstract: | Some algebraic explicit analytical solutions of the unsteady axisymmetric variable coefficient partial differential equation describing the temperature variation of a steam turbine rotor with center hole are derived and given. Probably such explicit solutions have not yet been published before. Besides their irreplaceable theoretical value, analytical solutions can also serve as standard to check the results of recently rapidly developing numerical calculation and to study various computational methods. In addition, some solutions in this paper are approximate to realistic condition and can be consultative examples in engineering practice. |
