The sufficient and necessary conditions of existence of the univalent harmonic orientationpreserving mappings f(z) are given,and f(z) satisfies the equation f =a(z)f z for given Beltrami coefficient a(z)= e iθ (z-a 11- a 1 z)(z-a 21- a 2 z) and maps unit disk U onto a given polygon P .

給出ａ（ｚ）＝ ｅｉθ（ ｚ－ ａ１１－ ａ１ｚ）（ ｚ－ ａ２１－ ａ２ｚ）存在將單位圓盤單葉調和保向地映射為已知的多邊形并滿足給定的Ｂｅｌｔｒａｍ ｉ方程ｆｚ＝ ａ（ｚ）ｆｚ 的映射的充分必要條件。

It is given that the sufficient and necessary conditions of existence of the univalent harmonic orientationpreserving mapping f(z) which satisfies the equation f =a(z)f z for given Beltrami coefficient a(z)= e iθ ((z-α)/(1-z)) m,m=1,2 and maps unit disk U onto a given polygon P .

我們給出當ａ（ｚ）＝ｅｉθ（（ｚ－α）／（１－αｚ））ｍ，ｍ＝１，２時存在將單位圓盤單葉調和保向地映射為已知的多邊形并且滿足給定的Ｂｅｌｔｒａｍｉ方程ｆｚ＝ａ（ｚ）ｆｚ的映射的充分必要條件。
