中文摘要：

振动的合成是物理学研究的内容之一，一般的振动合成问题比较复杂而自然界中最基本的振动形式是简谐振动，所有复杂的振动形式都可以分解成很多简谐振动．本文详细对一维谐振动的基本特征和几个常见问题做了详细的探讨．主要介绍了一维的简谐振动的合成方法，如代数法、振幅矢量合成法及其相量法，并且通过动力学基础分析了振动合成的过程，简明了各种不同条件下简谐振动合成情况．

英文摘要：

The synthesis of vibration is common physical phenomena, general vibration synthesis problem is more complex. Simple harmonic oscillator is the most basic vibration in nature, all complex vibration can be regarded as a number of simple harmonic oscillator synthesis. This article detailed the basic characteristics of one-dimensional harmonic oscillator and some common questions. This article mainly introduced the one-dimensional simple harmonic oscillator synthetic methods, such as algebra method, amplitude vector synthesis and the phasor method, and the synthesis process through the dynamical foundation.
