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。

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

This thesis presents the preliminary study of the influence of sentence stress on prosodic features in Mandarin, and of the relationship between duration and pitch under different sentence stress levels. The results show that: The pitch is the most important factor which carries the sentence stress, with the increase of the sentence stress level, the peak of distribution contour of pitch moves towards high frequency area. In the case of"Stress"and"Light", two peaks are found in the distribution contour of duration, which means that the duration of some words are affected by sentence stress, but of others are not. The relationship between pitch and duration in"Normal","Stress"and"Light" are un-correlated, positive correlation and negative correlation respectively.
研究了汉语语句重音对音长和音高的影响、及音长和音高之间的相互关系,结果指出:(1)音高是汉语语句重音的基本表达手段,随着语句重音级别的提高,音高的统计分布曲线向高频方向推移;(2)在连续语流中的词被&重读&和&轻读&的情况下,音长分布出现双峰,表示它们的音长存在着受语句重音的影响和不受语句重音的影响两种情况;(3)词在&正常&、&重读&和&轻读&三种情况下,音高和音长的相互关系分别是:不相关、负相关和正相关。

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。
