相位角

Time domain signal is transformed to the frequency domain signal by FFT. Dispersion curve is obtained from phase angle that is calculated by the frequency spectrum analysis. A compound dispersion curve is obtained from the dispersion curves intervale, and the representative dispersion curve is used to evaluate dimensions and quality of soil grouting body.

由FLAC所得不同点位的速度历时透过快速傅立叶转换后，得到频率域讯号，再经过频谱分析计算其相位角，得到其频散曲线，由不同间距的频散曲线集合成复合频散曲线，再绘制成一"代表性"频散曲线，以评估灌浆体品质及范围。

A new type of flexible microelectrode array s based on parylene is developed in this paper.

It is the first time thatthe interference phase angle is larger than 90°has been observed experimentally.

这是实验上首次发现干涉相位角大于90°的现象。

This effectively allows one to adjust the phase angle.

这实际上允许一个调整相位角。

Since the output signal from fringing field dielectrometry sensors under a low frequency driving voltage are very low, the shield-drive, signal buffer and band-pass filter are adopted to improve SNR. With the signal gain and phase angle from a transform circuit, the complex permittivity of pressboard are obtained.

鉴于边缘场电容式传感器在低频正弦驱动信号作用下输出的感应信号非常微弱，调理电路采用驱动屏蔽方式进行测量信号缓冲，用带阻滤波器提高信噪比，并利用相应的变换电路求出电容系统的相位角和幅值增益，从而得到绝缘纸板的复介电常数。
