汽车传动轴跳动图解析计算法

本文旨在用解析几何计算替代传统的几何画法求解汽车传动跳动图，使得解析计算求解法成为求解传动轴跳动图的有效方法；通过建立传动轴跳动的数学模型，运用计算机仿真技术在计算机屏幕上模似传动轴跳动．使得传动轴跳动图更具有直观性。

Novel Strategy for Numerically Evaluating Dark-Soliton Jitter in Optical Communications

In this paper, a novel strategy for numerically evaluating the dark-solitonjitter in optical communications is proposed. It is further tested to be consistent with the famousthreshold-value-oriented method for rather larger distances. Then our method is used to calculatethe dark-soliton jitter within arbitrary small distances. An excellent agreement is obtained withthe theoretical predictions based on the nonlinear Schrddinger equation. Our method is alsoapplicable to some more complicated systems such as the dissipative-dispersive system.

怎样识别故障是来自电视机还是电视台

平常看电视时,有时会遇到电视的某些瞬时异常现象,往往误认为是电视机故障。其实并不完全如此。下面根据电视图象区别一下哪些是电视发射台故障,哪些是电视机本身故障。 电视台故障主要表现在:①电视图像出现瞬时图像翻滚现象。
