MIDI Controller This feature will turn your acoustic piano into a MIDI Controller. With this system you can use your acoustic piano's keyboard to record music to a computer, send keyboard and pedal data to a digital piano, external sound module, sequencer or other MIDI device.

MIDI控制器这一功能可把你的声学钢琴成为一个MIDI控制器，有了这种系统，你可以用你的原声钢琴的键盘记录音乐，以一台电脑，送键盘和踏板数据，以数码钢琴，外部音源，音序器或其它MIDI设备。

In order to know interval velocity in layered acoustic medium,re- locity analysis is made using wave field continuation and fuzzy decision theories.

为了获得层状声学介质的层速度参数，文中依据波场延拓理论和模糊决策理论改进了速度分析。

Based on this, a new WENO difference scheme which based on Dispersion-Relation-Preserving relation is developed, and representative test cases with this scheme for computational aeroacoustics problems has been implemented and compared in order to test capability of wave capturing; In addition, WENO schemes generally do not converge at high order in the presence of contact discontinuity of Euler equations, so a conservative front tracking technique coupling WENO schemes and Level Set method to simulate the translating density profile is presented here, and numerical simulation with this technique for representative test case has been implemented and results show the desired accuracy.

本文研究了高阶精度加权基本无振荡格式及其在双曲守恒律方程中的应用，在此基础上作了两个方面的工作：一是针对高频声波问题构造出一种基于保色散关系的WENO有限差分格式，并对计算气动声学问题的代表性算例进行了大量数值实验，比较了该格式捕捉波数的能力；另外，针对高阶WENO格式在处理Euler方程的接触间断时精度有所降低的问题，研究了利用界面追踪技术Level Set方法和高阶激波捕捉WENO格式相结合的一种守恒追踪方法，并且给出有代表性的密度滑移面问题的算例，得到一致高阶精度的数值模拟结果。

It gives up the unreasonable spherical hypothesis which is out of accord with the reality.

考察了不同壁面、空泡离壁面的距离和空泡的气体含量对空泡演化及辐射噪声的影响，该方法将边界元方法得到的空泡演化情况与声学方程在特殊情况下的解结合起来，放弃理论分析上不合理的球形假设，并考虑了边界的影响，这样更符合实际的空化现象，得到了与实验相一致的结论。
