作者: AP Carr 摘要: Phase difference is defined as the ratio of time of uprush of swash ( t) to the wave period ( T) (Kemp, 1960, 1975). Using the ratio t/T, Kemp classified the wave-beach relationship into three... DOI: 10.1007/0-387-30843-1_323 年份: 1982 收藏...

When sound waves are combined, the beat is heard as a pulsation in the sound. Lash An attempt; a go at something. I'll have a lash. Beat A steady succession of units of rhythm. Lash Looseness between fitted parts, either intentional (as allowance) or unintentional (from error or wear)...
Student: Are you going to talk at all about the difference between radio waves and sound waves? Professor: Uh, Ok. That might be a good place to start actually. Sound waves are mechanical in nature, right? They can only originate and spread in places where there's some dense physical me...

A farskip on an Earth sized planet would require a roughly 2000 Hz refresh rate just to display the difference between a FTL and a STL farskip. In other words, there is no discernible difference between a FTL and STL farskip, and so farskip cannot be assumed to break the no FTL rule...
