摘要：
相位是影响多种光学现象结果的主要因素，例如量子叠加、波干涉和光与物质相互作用。当光波变为非静态时，其演化过程中会出现一个附加相位，即所谓的几何相位。由于该相位，量子波函数的整体相位随时间以非线性方式变化。有趣的是，如果非静态性度量极高，该相位会表现出阶跃式演化。为了更好地理解波的非静态性，本文对这种异常相位变化进行了详细分析。当波变得高度非静态时，电磁波的相位因子以矩形方式演化。然而，由于波幅的补偿性变化，电磁场的形状仍为正弦形式。这种情况下的电磁场非常类似于驻波。本文分析了伴随阶跃相位演化出现的效应，例如概率分布的修正和波干涉轮廓的改变，并说明了它们的意义。
英文摘要：
The phases are the main factor that affects the outcome of various optical phenomena, such as quantum superposition, wave interference, and light-matter interaction. As a light wave becomes nonstatic, an additional phase, the so-called geometric phase, takes place in its evolution. Then, due to this phase, the overall phase of the quantum wave function varies in a nonlinear way with time. Interestingly, the phase exhibits a step-like evolution if the measure of nonstaticity is extremely high. Such an abnormal phase variation is analyzed in detail for better understanding of wave nonstaticity in this work. As the wave becomes highly nonstatic, the phase factor of the electromagnetic wave evolves in a rectangular manner. However, the shape of the electromagnetic field is still a sinusoidal form on account of the compensational variation of the wave amplitude. The electromagnetic field in this case very much resembles that of a standing wave. The effects accompanying the step-phase evolution, such as modification of the probability distribution and alteration of the wave-interference profile, are analyzed and their implications are illustrated.
