Conceptually, the most obvious sample point within a fundamental period is often referred to as the pitch mark. Usually pitch marks are selected as the local maxima or minima of the audio waveform. In the previous example of pitch determination for the tuning fork, we used two pitch marks that are local maxima. On the other hand, in the example of pitch determination for human speech, we used two pitch marks that are local minima instead since they are more obvious than local maxima.

在观察音讯波形时，每一个基本周期的开始点，我们称为「音高基准点」（Pitch Marks，简称 PM），PM 大部分是波形的局部最大点或最小点，例如在上述音叉的范例中，我们抓取的两个 PM 是局部最大点，而在我的声音的范例中，由於 PM 在局部最大点并不明显，因此我们抓取了两个局部最小点的 PM 来计算音高。

The proposed receiver-based PLC method detects the pitch lengths of the waveform in the two sides, determines the number of pitch cycles and pitch lenghts to be placed into the lost packet, and interpolates the pitch waveforms from the two sides to synthesize pitch waveforms. This method is called Time-Proportion Based Pitch-Waveform Interpolation. When compared with other waveform reconstruction methods, e.g.

本论文提出的接收端补偿方法，首先会去侦测遗失封包的前一个与后一个封包内的基周长度，接著决定重建出的基周在遗失封包内需要布放的个数与个别长度，最后内差出各个基周的波形，此方法我们称之为时间比例式基周波形内差法。

Studied the solid particles cyclone separation under structural parameters and operating parameters of different hydrocyclone, the results showed that major factor influence split ratio is in the ratio of entrance to exit pressure of hydrocyclone. Exit pressure has a certain influence on the split ratio, the various of the diameter and cone angle of hydrocyclone (in the ratio of entrance to exit pressure is constant) have no influence on split ratio; With diameter and cone angle increase, the separation granularity gradually increasing and recovery ratio decreasing; With entrance pressure increase, the separation granularity of hydrocyclone decrease, the split ratio of underset will increase slowly; With the diameter of overflow pipe increase, the separation granularity of hydrocyclone increasing and recovery ratio decreasing; With the diameter of underset pipe increasing, the separation granularity of hydrocyclone decreasing and recovery ratio increasing.

在不同的水力旋流器结构参数和操作参数下，对固体颗粒的旋流分离进行了分析研究，结果表明：旋流器的排出口比是影响分流比的主要因素，进口压力对分流比有一定影响，水力旋流器的直径变化和锥段角度变化对分流比基本上没有影响；随着直径、锥段角度的增大，分离粒度逐渐增大，回收率降低；随着入口压力增大，水力旋流器的分离粒度变小，底流的分流比会缓慢增加；随着溢流管管径的增加，分离粒度增大，分流比明显减小，回收率降低；随着底流管直径的增加，分离粒度减小，分级效果明显下降，回收率会增加。
