Front velocity (original) (raw)

Property Value
dbo:abstract In physics, front velocity is the speed at which the first rise of a pulse above zero moves forward. In mathematics, it is used to describe the velocity of a propagating front in the solution of hyperbolic partial differential equation. (en) En mécanique ondulatoire, la vitesse de front est la vitesse à laquelle la première montée d'une onde qui croise l'axe horizontal se déplace. En mathématiques, ce terme est utilisé pour décrire la vitesse de propagation d'un front dans la solution d'une équation aux dérivées partielles hyperbolique. (fr) 物理學中,波前速度(Front velocity)是一脈衝大於零值的第一個陡坡其前行之速度。 在數學中,波前速度則用於雙曲型偏微分方程的解,描述傳遞波前之速度。 (zh)
