简谐振动和简谐波中相位的分析

Analysis of Phase in Simple Harmonic Vibration and Harmonic Waves

通过对相位深入具体地分析并结合按余弦规律运动物体的运动过程,对简谐振动及简谐横波的函数表示法和图象表示法做了系统研究,实践结果表明对已知图象写方程和已知方程画图象应用分析相位的方法简单可行。对教学研究是一种方便有效的方法。

Based on thorough analysis,in combination with the motion process of object that takes motion satisfying cosine law,a systematic research of function representations and images of harmonic vibration and harmonic shear waves have been made in this paper.The practical results show that application of phase analysis method to writing equations while images are known and drawing images while equations are given is simple and feasible.This is a convenient and effective method to teaching and research.
