An open cylindrical air column 0f length L = m = ft

一个开口的圆柱形气柱,长度 L = m = ft
中文译文中的待填/计算数值依次对应:1:l 2:lc。实际数值以上方原输入框为准。

will produce a fundamental frequency:

将产生基频:
= Hz
= 赫兹
中文译文中的待填/计算数值依次对应:1:f。实际数值以上方原输入框为准。

In actual practice, the position of the antinode is slightly outside the open end, and an end correction of about 0.6 times the radius of the pipe should be added to each end to get the effective acoustic length.

实际上,驻波的节点位置略在开口处之外,为得到有效的声学长度,应在每个端点加上约0.6倍管径的端部修正。
