Based on vibration principle, the paper establishes dynamics analysis model of output shaft with elastic support, according to fourer series spread principle of periodic function, the dynamic response formula is derived by separating complex vibration force into sum of many simple harmonic excitation function of whole number times frequency relations. the result shows that response of both sides support is synchronous when load distribution non - uniform coefficient is 1
依據振動理論建立了具有彈性支撐的輸出軸的動力學分析模型，根據周期函數的傅里葉級數展開原理，將復雜的激振力分解成為多個頻率成整倍數關系的簡諧激勵函數，導出了動態響應表達式，結果表明，當載荷分配不均勻系數為1 . 0時的輸出軸兩端支撐同步。 -

The first chapter of this article consists of the following contents. suppose that are positive integers., then the bergman kernel function for the second type of hua domain where determined by the following recursion formula : and where is determined by the following recursion formula : it is inappropriate to use holomorphic transitive group to compute the bergman kernel function of hen because he11 is not a homogeneous domain, and we can not obtain the bergman kernel function of hen by obtaining the sum of an infinite series as we compute the bergman kernel function of reinhardt domain. we firstly give some holomorphic automorphisms such that for any he there exists a holomorphic automorphism satisfying next, we introduce the concept of semi reinhardt domain and get its complete orthonormal system
結合上述兩種方法就可獲得he _的bergman核函數的顯表達式，對于兩類廣義例外華羅庚域，還要用到jordantriplesystem的理論，才能求出其bergman核函數的顯表達式： 2當是正整數，時，廣義例外華羅庚域的bergman核函數其中滿足如下的等式：於是，可從等式得到所有的a _ j ， ry u dstu thalca000ereereereforfortheerethettithen其中廣； k由下歹遞推公式決定： 。 -
