| 摘 要： | 通过引入身气泡的方法可减少船（或艇）在水中的摩擦阻力，作为这一问题的部分工作，对平板在自由来流情况下的层流边界层用伪谱方法进行了数值模拟，直接用伪谱矩阵方法对边界层方程进行离散计算，与经典结果相比较，本方法求解的结果精度一致，速度更快。

| Abstract: | The numerical simulation on a plate with free coming flow at infinite distances has been processed with pseudo spectral methods. The boundary layer equations are dispersed with pseudo spectral matrix and computed. The results are compared to classical results. It is found that the present results have the same precision and with a faster speed. |
