摘 要: 对区间[0,s]进行均匀分划,在所得的子区间内选取适当的近似解析解形式,然后运用热平衡积分法,进而对热平衡积分法进行了细化.通过讨论得知:当β值大于5.5时,细化的热平衡积分法才能很好地提高所求解的精度. Dividing the interval [0,s] evenly partition, and then selecting the appropriate form of approximate analytic solution in the obtaining sub-interval to use the heat balance integral method, therefore, the heat balance integral method is refined. It shown that when βis greater-than 5.5, we can raise the accuracy of solution by using the refined heat balance integral method.
