相位 Phase (waves)

（重定向自Phase shifting）

相位（phase），是描述信号波形变化的度量，通常以度（角度）作为单位，也称作相角。当信号波形以周期的方式变化，波形循环一周即为360º。常应用在科学领域，如数学、物理学、电学等。

Phase (waves) 相位

（重定向自Phase shifting）
Illustration of phase shift. The horizontal axis represents an angle (phase) that is increasing with time.
Left: the real part of a plane wave moving from top to bottom. Right: the same wave after a central section underwent a phase shift, for example, by passing through a glass of different thickness than the other parts. (The illustration on the right ignores the effect of diffraction, which would make the waveform continuous away from material interfaces and would add increasing distortions with distance.).
Mit konstanter Kreisfrequenz ω rotierender Zeiger der Länge û . Der Phasenwinkel φ(t) nimmt linear mit der Zeit zu. Die Projektion des Zeigers auf die x-Achse ist û cosφ.

Phase in sinusoidal functions or in waves has two different, but closely related, meanings. One is the initial angle of a sinusoidal function at its origin and is sometimes called phase offset or phase difference. Another usage is the fraction of the wave cycle that has elapsed relative to the origin.
