The Hilbert amplitude envelope of the stator current includes the low frequency of fault characteristic, thus it can reduce the signal length by resample the Hilbert amplitude envelope of the stator current by downsampling, which can avoid spectrum aliasing. Then it can reduce the computation time of the MUSIC Method for the spectrum analysis to the resampled signals for the given bandwidth. Meanwhile combining continuous subdivision Fourier transform and rotor slot harmonics based slip estimation it can in advance estimate the concrete values of the fault characteristic frequency, and then inquiry purposely the fault feature component information in the stator current spectrum in order to accomplish the broken rotor bar fault with high sensitivity and h reliability, which eliminates adverse effect of issuable false peaks to the fault detection and formed a novel scheme to detect broken rotor bar fault.

定子电流Hilbert幅值包络信号包含了低频的故障特征频率调制信号，故通过对定子电流Hilbert幅值包络信号进行降采样率重采样、减少分析信号长度，可避免低频段频谱混叠，再对减少的重采样数据进行具有超分辨率的MUSIC低频段估计，可大大降低MUSIC算法频谱估计时间；运用连续细化傅里叶变换和转子齿槽谐波转差率估计技术，可预知故障特征频率精确值，从而可有目的地查询故障分量，消除MUSIC虚假波峰对故障检测混淆的影响，大大提高了故障检测的灵敏度和可靠性，以此形成异步电动机转子断条故障检测新方法。

One very useful way to tweak a reverb patch is to postpone its onset with predelay.

Predelay，就是在混响之前扯出一段延迟时间。

He contact Seo also is not too long, in a way sums up the experience that plays his, should be mix in A5 so a bit longer be contributed smally!

本人接触seo也不是太长时间，稍稍总结下自己的经验吧，当是在A5混这么久一点小小的贡献吧！

The actual institution of teaching and learning was called studium, or studium generale if its influence was especially significant, although neither of these terms should be pressed very hard in light of the marked diversity among the early studia and the decades involved in regularizing their practices.

实际的教学机构则称为studium，如果影响突出，则称之为studium generale。不过，考虑到早期大学的多元性，以及规范大学行为需要耗费漫长的时间，这两个术语都不是非常严格的。终于混成钻石会员了。
