| 摘 要： | 在弦振动“驻波“实验中,对于起振端是波节还是波腹,存在不同的认识。本文给出了弱阻尼状态下弦振动实验的严格解析解,利用该解分析了上述问题,并且发现通常认为的弦振动实验形成明显驻波的条件并不完全正确。

| Abstract: | There are different viewpoints about the wave source in the experiment of vibration of string. In this article, the rigour wave function of vibration of string in slight damp is given, and the problem is analyzed using the function. In addition, it is found that the classical conclution about formtion of distinct stationary wave isn't right absolutely. |
