具有时滞的可燃物的湿度模型

可燃物是森林燃烧的物质基础,可燃物的湿度变化一定程度上决定着火灾的形成,所以建立可燃物湿度模型对研究可燃物湿度变化有很大的帮助,笔者通过建立可燃物湿度模型来研究可燃物湿度的变化情况。在研究中充分考虑了气象因子对可燃物湿度的影响,并且加入了时滞情况,研究结果表明可燃物湿度受到气象因子的影响,并随着气象因子的变化而变化,在对气象因子进行相关性分析的基础上,得出结论：可燃物的湿度与气温风速呈负相关、与湿度气压呈正相关,建立的可燃物湿度模型在考虑气象因子的影响的情况下基本可以预测一小时后可燃物湿度的变化情况,希望对森林的防火有所帮助。

Time-delay model of fuel moisture

Combustible is the material basis of forestfive.To some extent,combustible humidity changes determine the formation of fire,so the establishment of combustible humidity model has a great help to investigate the combustible humidity changes.This article is through the establishment of combustible humidity model to study the combustible humidity changes.In the study,the paper takens full consideration of the meteorological factor influence on the humidity of combustible and joined in the case of time-delay.Research results show that meteorological factors affected the humidity of combustible that changes with meteorological factors change.Based on the correlation analysis of meteorological factors,it draws a conclusion that the humidity of combustible is negatively correlated with temperature and wind speed,positively correlated with humidity and air pressure.Considering the influence of meteorological factors,the combustible humidity model built in the article can predict the changing situations of the combustible in humidity one hour later,hoping to help in preventing the forest fire.
