Rotating shafts experience a an elliptical motion called whirl. It is important to decompose this motion into a forward and backward whil orbits. The current function makes use of two sensors to generate a bi-directional spectrogram. The method can be extended to any time-frequency distribution

现在有好多初学jsp的网友经常会问数据库怎么连接啊，怎么老出错啊？所以我集中的在这写篇文章供大家参考，其实这种把数据库逻辑全部放在jsp里未必是好的做法，但是有利于初学者学习，所以我就这样做了，当大家学到一定程度的时候，可以考虑用MVC的模式开发。-now have many novice jsp netizens often ask how database linking ah, ah how old mistakes? So I concentrated on writing this article for reference. Such logic of the database on all jsp Lane is not necessarily a good one, but is conducive to beginners learning, So I do this, when we learn a certain extent, we can consider the use of the MVC pattern of development.
