By this linearization model, the speed tracking control law is designed to increase the celerity of speed tracking while keeping the whole closed loop system stable.
通过此方法设计的速度跟踪控制,在保证整个闭环系统稳定的情况下,提高速度跟踪的快速性。
Search Enginer is an integrated system in multi-technologies. The key point to estimate search Engine is how to refer the celerity and nicety search results for users.
搜索引擎是一个集多种技术于一体的综合性系统,如何将查询结果快速、准确地提交给用户是评价搜索引擎优劣的一个重要因素。
For breaking wave the horizontal particle velocity can be taken as the wave celerity, since the wave is breaking when horizontal particle velocity is equal to or larger than the wave celerity.
而对于破波,质点的水平速度应该等与波速,由于破波产生的极限就是质点的水平速度等于或大于波速。
