Based on the polynomial fitting of power function, FFT of sinusoidal function and 1-level decomposition of Daubechies wavelet, the simulation shows that the approximation of DT and the gradient depend on the width of horizontal distance spectrum.

文章基于幂级数多项式拟合、三角函数的FFT 和一级Daubechies 小波分解的理论分析以及数字地形的数值仿真，研究了近似地形的精确度与坡度的确定性因素。

The authors used the method of trigonometric series and polynomial to solve the problem for the bending of a cantilever plate in a symmetric triangular shape under uniform load.

作者以前应用三角级数加多项式的方法解决了悬臂对称三角形板在均布载荷作用下的弯曲问题。

By using Taylor series approximation and convex polytope technique, exponential uncertain discrete-time switched linear system is transformed into an equivalent switched polytopic model with an additive norm bounded uncertainty.

利用泰勒级数逼近和凸多面体技术，将上述系统转化为等价的具有模有界的多项式不确定模型。

In this thesis, by employing generating function technique, some new combinatorial identities have been established. Furthermore, the integral values of some kinds of series involving generalized Fibonacci and Lucas numbers at rational numbers are given and the values of some polynomials at rational points have been studied as well.
