Finding the periodical solution in analytical form of a nonlinear vibration problem on computer is an entirely new matter.In this paper, we attempt to reach the goal by using curve-fitting method. We first look for the numerical solution of a nonlinear differential equation x+p_0~2x=∈(x, x,∈) which has specific small parameter ∈ and specific initial conditions x_0=A and x=0. Then we find out its period and main frequency and resolve it into harmonic components with Fourier Method. When we have done the...

Finding the periodical solution in analytical form of a nonlinear vibration problem on computer is an entirely new matter.In this paper, we attempt to reach the goal by using curve-fitting method. We first look for the numerical solution of a nonlinear differential equation x+p_0~2x=∈(x, x,∈) which has specific small parameter ∈ and specific initial conditions x_0=A and x=0. Then we find out its period and main frequency and resolve it into harmonic components with Fourier Method. When we have done the similar work for sufficient number of differential equations with different small parameters and different initial displacements, we seccessfully find out the frequency function and displacement response function of the differential equations with varying small parameters ∈ and varying initial displacements A by using curvefitting method. These functions are shown as power series in ∈ and A. The example shows that the method is more accurate than perturbation method.

在计算机上求非线性振动问题的解析形式的周期解是件全新的事。本文中,我们试图用拟合法达到这一目的。我们首先求具有特定小参数∈并具有特定初始条件x_0=A,x_0=0的非线性微分方程x+p_0~2x=∈f(x,x,∈)的数值解,然后找出其周期和主频率,再用付立叶方法把它分解为诸简谐分量。在对数量足够多的具有不同小参数和初始位移的同类微分方程做了与上述相同的工作之后,我们成功地用曲线拟合法找出了具有变化的小参数和变化的初始位移的微分方程的频率函数和位移响应函数。这些函数都是以小参数∈和初始位移A的幂级数的形式表达的,例题说明本法的精度高于摄动法。

According to the trend of development of theories, technologies and devices in electronic warfare, the signal processing techniques of radar in 1990s and a first-look arc further forecasted.

在电子战时代,随着各种反雷达技术(如隐身技术、电子侦察机和电子干扰机等)的发展,雷达技术的目的已不单纯地强调监视目标的能力,而更强调雷达生存能力。本文介绍在80年代监视雷达中所采用的主要信号处理技术,并从电子战理论、技术和器件的发展趋势,进一步预测了90年代雷达的信号处理技术及其发展前景。
