When the persisted property is applied to a computed column , indexes can be created on the column when the column is deterministic , but not precise 浏览模式具有几个浏览模式函数,应用程序可使用这些函数返回的信息来检查复杂的即席查询的结构。
In the second , in allusion to non - stationary the characteristic of the signal , the author introduces to the method that using empirical mode decomposition to analysis the vibration signal so that the signal are made up of some intrinsic mode function , after this process , we can use stochastic subspace identification to identification the mode parameter of the structure and find the same work frequency 其次,针对气阀振动信号的非平稳特点,本文采用了经验模式分解法( empiricalmodedecomposition )对振动信号进行分析处理,使之成为若干个基本模式函数imf ( intrinsicmodefunction )和一个残余量的线性组合。接着采用随机子空间参数识别法对各个基本模式函数其进行结构参数识别,同时找出各种状态的共同工作频带。
