需要考虑共鸣时管口辐射导致的末端效应，在计算声速时管长应加上一个修正值，同时还需截断频率较高的数据点.实验易于

实现，数据处理的过程对于学生的数学建模、数据发掘与提取等方面的能力也有很好的训练作用.

of the limitation of the simple equipment used in the experiment，the air column is short and thick，so it is

necessary to consider the endeffect caused by the acoustic radiation of the orifice during the resonance. The experiment

is easy to be implemented，and the data processing is helpful for training students’ability of mathematical

modeling，data mining and extraction.
