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。

Tooth Proportions.—There are 17 pitches: 2.5/5, 3/6, 4/8, 5/10, 6/12, 8/16, 10/20, 12/24, 16/32, 20/40, 24/48, 32/64, 40/80, 48/96, 64/128, 80/160, and 128/256. The numerator in this fractional designation is known as the diametral pitch and controls the pitch diameter; the denominator, which is always double the numerator, is known as the stub pitch and controls the tooth depth. For convenience in calculation, only the numerator is used in the formulas given and is designated as P. Diametral pitch, as in gears, means the number of teeth per inch of pitch diameter.
齿比——一共有17种齿比:2.5/5,3/6,4/8,5/10,6/12,8/16,10/20,12/24,16/32,20/40,24/48,32/64,40/80,48/96,64/128,80/160和128/256在这一系列的分数中的分子是径节,径节的大小决定了节圆的直径;而分数中的分母通常是分子的两倍,分母是残余径节,它的作用是控制齿槽的深度为了方便计算,在所有的公式中都使用分子作为计算参数,并且与齿轮的表示方式一样定义为径节P尺寸,也就是在节圆上,每英寸长度上的齿数

Pitch is a combination number of a one-to-two ratio indicating the spline proporti******; the upper or first number is the diametral pitch, the lower or second number is the stub pitch and denotes, as that fractional part of an inch, the basic radial length of engagement, both above and below the pitch circle.
径节分数:径节分数是由两个数组成的一个比率,它表示的是花键的比例;设这个比率为A/B,则在这个分数中第一个数A表示的是花键的径节,第二个数B表示的是残余径节,径节表示的是在节圆上方的键齿在半径方向上的结合长度,残余径节表示的是在节圆下方的键齿在半径方向上的结合长度。

The results show that the coal pitch based activated carbon not only has good sphericity but also narrow particle size; with the same material pitch, the more naphthalene content, the lower the softening point of the modulated pitch. The max mass ratio of pitch to the liquor is 16 and the optimal speed is different using different stirrer.

Correctional checking formula of melt flow ratio in injection molding was obtained by introducing a correction coefficient β which reflected the complexity degree of mold cavity. The results show that, the maximum flow ratio of 486 can be obtained when injection pressure ranges from 150 MPa to 160 MPa in Archimedes spiral mold for PP, while maximum flow ratio of 419 can be obtained when injection pressure ranges from 160 MPa to 170 MPa for PE. There is a local fluctuation phenomenon for flow ratio and corresponding injection rate in square spiral mold when injection pressure of 100, 120 and 150 MPa for PP and 130, 140 MPa for PE are reached respectively,and this phenomenon is more serious for good fluidity of melt. The average flow ratio in Archimedes spiral mold is 6% larger than that in square spiral mold for PP, and 4% for PE, the average flow ratio of PP is 19% bigger than PE in Archimedes spiral mold, and 15% in square spiral mold. The influence of the cavity profiles on the melt flow ratio is more significant for good fluidity of melt.

Roundness tolerance of pitch diameter Roundness tolerance for a minimum of 345o circumferential arc of the pitch diameter shall not exceed .002 inch (0.051 mm) total, or one half the pitch diameter tolerance if the pitch diameter tolerance is less than .004 inch (0.102 mm); roundness tolerance of the remaining 15o maximum circumferential arc shall not exceed .004 inch (0.102) total, provided such tolerance does not result in excrescence on the thread flank.
