coherent wave 是相干波。那么应该是频率相等。in phase 指的是相位相同
A regular heartbeat is essential to vertebrate life. In the mature heart, this function is driven by an anatomically localized pacemaker. By contrast, pacemaking capability is broadly distributed in the early embryonic heart1,2,3, raising the question of how tissue-scale activity is first establi...

Tags Phase Standing wave Standing waves Wave In summary, the conversation discusses the phase differences between points P, Q, and R in a standing wave. The points P and R are pi radians out of phase, reaching their max/min at the same time. Antiphase is a phase difference that is an ...
In the first phase,chicks are hatched from eggs. 寒冬时节,家里的鸡开始孵化小鸡崽。 二候| 征鸟厉疾 In the second phase,predatory birds search for food. 冰天雪地里,鹰隼食物匮乏,常在空中盘旋,比平时更加凶悍。 三候| 水泽腹坚 In the third phase,the surface of water freezes to a solid mass...
When a material object is placed in the path of an electromagnetic wave, the latter undergoes a change in both its amplitude and its phase. In particular, calculations have been performed previously for two extremes (1) to obtain the contrast caused purely by the change in amplitude produced ...
Finally, when gas and liquid are in contact with each other in a two-phase flow, the boundary between them is influenced by physical effects, such as inertia, capillary forces or shear [97]. 2.2 Two-phase flow patterns In two-phase flow, mass, momentum, and energy transfer processes and...
a, b Superpositions of three density waves with the wave vectors Q1, Q2, and Q3. b is the figure generated from a with the phase shift of π/2 in Q1, which breaks sixfold rotational symmetry in a. c, d superpositions of three spirals waves: the nsk = 1 skyrmion crystal (SkX1...
