If you don't need a property indexed (that is, you don't plan on searching a domain object by that individual property), then turning off that index probably makes sense.

如果您不需要对某个属性建立索引(也就是说，您不计划通过该单个属性搜索域对象)，则关闭该索引可能是有意义的。

This means that every time you create, update, or delete a domain class, the Lucene index is updated accordingly.

这就意味着每当您创建、更新或删除一个 domain 类时，Lucene 索引都会相应更新。

It is more reasonable that the dynamic performance index both in frequency domain and in time domain should be calculated from model calculated frequency response and unit-step response.

由参数模型计算的阶跃响应与频率特性上计算时域与频域的动态性能指标才比较合理。
