| 摘 要： | 提出建立高维解析不等式的拟单调函数方法．获得的主要结果是：在适当的假设下，如果涉及齐次对称函数的不等式问题可用优超理论或差分代换平凡非负方法处理，那么这类问题也能用拟单调函数方法处理．同时，用该方法处理了一类涉及幂平均的线性不等式问题．

| Abstract: | In order to establish a lot of analytical inequalities on high-dimensional space,a method of quasimonotone function was proposed.The main results are the following:with the proper hypotheses,if the problems of inequalities involving symmetric homogeneous functions can be settled via the theory of majorizations or the trivial non-negative of difference substitution,then these problems also can be settled by quasimonotone function method.For applications,several problems of linear inequalities involving power... |
