Gap junctions are the direct pathways to exchange signals among cardiac myocytes. The electrical conduction velocity there is faster than other place on cell membrane.
缝隙连接是细胞间信息交换的直接通道，此处的电传导速度比细胞膜上其他部位都快。

Fluidization properties of the ion exchange resins packed bed have been experimentally studied. Based on test results, formulas for fluidization velocity is established.
This paper defined time, space, displacement, velocity, acceleration, and raised axiom of Galileo exchange, which is the basis of axiom system in particle mechanics.
