湍流运动论中的化学反应速率扰动

Turbulent Chemical Reaction Rate of the Disturbance

在分子与分子之间发生碰撞时,如果分子的动能足够大,当超过一定的阈值E时,分子碰撞就会发生化学反应.然而气体分子化学反应速率是受到一定因素影响的,诸如分子数密度n、温度T以及速度V.日本学者Sagara于上世纪70年代曾对分子数密度n和温度T对反应速率的变化做了深入的探究.主要是在此基础上利用二粒碰撞机理论对速度以及温度和速度的共同作用来研究反应速率的变化情况.

In the collision between molecules, if the kinetic energy of molecules is large enough, which exceeds a certain threshold E, the molecular collisions occur a chemical reaction. But the chemical reaction rate of gas molecules is subject to certain factors, such as the number of molecules density n, temperature T and velocity V. In the 1970s, Japanese scholars Sagara has researched the molecular number density and temperature on the reaction rate changes. This paper is on this basis, to reseach the changes of the reaction rate from the angle of the velocity and then temperature and velocity interaction.
