The system rated pressure shall be the lowest of the fitting, tube or joint.
系统额定压力应该是管件、管道或连接部位的压力额定值的最低值。

A constant rotational speed can be restored by fitting a second joint in a way such that when the first joint increases its speed the second joint decreases its speed.
要实现等速，必须以某种方式安装第二个万向节，这样第一个万向节使转速增大，第二个万向节就使转速减少。

The fitting difference is reduced and the precise of quantitative interpretation is improved by means of joint TF inversion with time and frequency window data.
