| 摘 要： | How would the ideal fluid columm in a communication tube moves,the present paper presentstwo different solutions,one of which has been existing in the literature not less than a half century,while the second is recommended by us with this article.We have deduced the differential equationanew and given the main motion features.According to our opinion,the hitherto,for a long time broadly used,derivation is not undis-putable.Noticeably,the results of our new derivation can duely degenerate into Newton-,JohnBernoulli-and Daniel Bernoulli-period laws of vibration.
