难达到

Has a remarkably wide range, though it is difficult to achieve (the high b makes the first string very taut such that it will break easily), and may not play well on an acoustic guitar (the low C is too low to resonate properly in a standard guitar's body). Luthier Todd Keehn claims to have been the first guitarist to adopt an all-fifths tuning, his being arranged G-D-a-e-b'-f#', and he has made an all fifths tuned guitar that can be seen at his website, http://tkinstruments.com/.

这个调弦的音域相当地宽，但是也很难达到要求（高音B使第一弦崩得非常紧，容易断）这个调弦在原声吉他上的效果也不理想（低音C太低在普通的箱琴上无法产生共鸣）据说Luthier Todd Keehn是第一个用这种调弦的吉他手，他还用 G-D-a-e-b'-f#调弦，他的全五调弦的琴可以在他的网站上看到 http：//tkinstruments.com/。

As the mine accidents happen frequently in recent years, the detecting technology for microseism becomes much more important. However, there is no advanced microseism detecting system at home. It's pretty important for microseisms denoising and Reversion. A wavelet denoising method is presented here to process microseism signal, and the microseism record can get high signal to noise ratio. Meanwhile based on the software of LabVIEW, s design of real-time detecting system for microseism based on virtual instrument is presented. The advantage of the virtual instrument was sufficiently exerted to achieve the real-time detecting and analyzing of the microseism.

以往基于DSP或其他单片机的微震系统，其资源的有限性很难达到理想的采集效果，同时也难以完成先进算法的实现，而对微震信号的去噪与还原在监测系统中起着很重要的作用；在深入分析小波变换的信号去噪方法基础上，对微震信号进行了处理，得到高信噪比的微震记录，实现了对噪声的有效抑止；同时在LabVIEW平台软件设计的基础上，实现了一种基于虚拟仪器微震实时检测的设计方案，充分发挥了虚拟仪器的优势，结果表明基于LabVIEW的微震系统能很好地完成实时监测及其分析。
