对于文中研究的液滴，无量纲完全蒸发时间随烟气温度变化呈指数递减规律。

For the droplet considered, the life time of droplet reveals the index declining rule along the flue gas temperature varying.

结果表明，流密度随时间按指数规律递减，而传递系数却按指数曲线递增。

The results show that exergy flow density is declined in exponent regularity while exergy transfer coefficient is increased progressively in exponent regularity.
