The inventor is excited, and he is going to try out his new machine. His idea sounds fine, but we need to try it out in practice.
这位发明家很兴奋，他要试一下他的新机器。他的主意听起来不错，但我们要在实践中试验一下。
The Excited frequency of forced vibration diverge from the Natural frequency of the machine tool, and the machine tool can be put on the practical application.
机床受迫振动的激振频率避开了机床的固有频率，该机床可以投入实际应用。
Because of the exciting action by the vibrating machine and the influence of wave propagation, broken ores will generate excited response when ores are mucked out by vibration.
振动出矿时，由于振动机的激励作用和波动传播的影响，碎岩便会产生激励响应，这种激励响应可以改变散体的动力特性和流动特征。
It is well-known that machining efficiency doesn't depend on the machine power and the load which machine can bear, but depends on the condition in which self-excited vibration appears.
机床的切削效率往往不是由机床的功率、机床所能承受的最大载荷所决定，而是由机床切削时发生自激振动的条件所决定。
