摘要利用由三角级数和幂级数复合构成的函数项级数的有关性质，得到了一类变系数非齐次调和方程边值问题的级数解。
In this paper by using the property of Fourier series a compound series consisting of trigonometric series and power series is established.
本文目的在综合叙述及推导复合指数函数的幂级数之系数间相关不等式。
In this paper, we describe some inequalities for the Taylor coefficients of a composite exponential function.
在求解各级迭代方程中，文中将解近似地用有限项幂级数表示，并数值地求解此级数各项的系数。
In solving each iterative equation, the solutions are approximately expressed by the power series with finite terms and the coefficients of the power series are determined by the numerical method.
