The method was rapid, simple and accurate. The correction factors of PETA were obtained by solving simultaneous linear equation.
用解联立线性方程求校正因子的方法，在缺少纯标样的场合可推荐应用。
By applying the transfer matrix method to the finite strip method the more simultaneous frequency equation is thus simplified to a two-frequency equation problem.
此法是将有限条法与传递矩阵法结合使用，一般能将频率方程压缩到二阶，对于变厚板显得更为有效。
