APPLICATION OF A INEQUALITY IN ANALYTIC FUNCTION 一个不等式在解析函数中的应用 The copula "是" in the copular construction is a predicate operator in essence, which has no semantic content and whose major task is to transfer the property denoted by the noun into a propositional function so as to realize the predication relation. 系词句中的系词“是”从本质上来说是一个谓词性算子(predicationoperator)，本身并没有任何实际意义，它所起的主要作用就是将名词具有的性质义转化为命题函数，来满足主谓关系的需要，其逻辑类为<π； but f(z) is an arbitrary analytic function and doesn't vanish at any Z_j((j=1,2,…1).The similar residue is true for the general sol- utions of Euler's equations. 其中g(x)是z 的n次多项式,在z_j (j=1,2,…l)的值为零,f(z)是任一个解析函数,=1,2,…l)的值不为零. 欧拉方程通解有类似结果. Thus in discussing the field value of the function and drawing range curves,we should state the field value on field source in the following. 因此,在写场的函数式及画场的分布曲线时,应把场源面上的场值表示出来。 It is brief and to the point that enropy function is led by the basis of Euler' s criterion of complete differential. 本文根据全微分的欧拉(Euter)判据引出熵函数,简明扼要。 By [x] we denote the least integer not less than x,et f (n) =n+[k/n]be a function of n with domain of set of positiveintegers, where k is a given positive integer. 以[x]表不小于x的最小整数,设函数f(n)=n+[k/n],其中k为给定正整数,自变量n在正整数集取值。 In this paper, we discuss the application of the H(?) lder inequality in univalent function and Hp spaces. We obtain some new results, some of them are the extension of Huko and M. Mateljevic's. 本文给出了推广的Hōlder不等式在单叶函数和H~P空间中的若干应用,得到或推广了一些重要结果。 This paper applies the theory of partial inverse operator and Green function methed for Nonlinear boundary Value Problems, Combining method of upper and Lower Solutions,discusses the existence of solution of the Secend order nonlinear Integral Differential equations and nonlinear two ponint boundary Volue problem's of the equation: x″=f(t,x,Tx) a
