pitch contour

When measuring, based on the segmented contour line of thread, the measurement program to calculate and measure the geometrical parameters of internal taper thread is compiled. Precisions of pitch, thread angle and taper angle reach ± 0.03mm 、± 0.24 ° and ± 0.02 °.

使用自编程序测量计算了内螺纹的螺距、牙型角和锥角，测量精度分别达到了003mm，024°和002°。

In this thesis, the problem of Min-Nan syllable pitch contour generation is studied.

本论文研究闽南语语音合成中音节基周轨迹产生之问题.

The normal lines of the cam pitch curve at the meshing points intersect at the instantaneous center of the cam and the pin gear, which accords with the meshing principle of tooth contour.

在凸轮与针轮啮合的瞬时，各针齿与凸轮啮合点处，凸轮理论廓线的法线交汇于该瞬时凸轮与针轮的速度瞬心，符合齿形啮合基本定理。

Then the speech signal is pitch adjusted according to this pitch contour, where the original signal with time varying pitch period is converted to a signal of constant pitch period.

然后根据这一轨迹对语音信号进行基音调整，将原始的、具有时变基音周期的信号转化为一个具有恒定基音周期的信号。
