基于细水雾作用的原木楞堆温度场的相关性研究

Regression on Temperature Fields of Log Piles Based on the Effect of Water Mist

对落叶松原木楞堆做细水雾灭火实验,测定实验过程中楞堆各点的温度,利用SPSS软件对定点间温度场进行相关性分析、线性回归分析。研究结果表明:原木楞堆前部温度与其后部温度、左侧温度变化存在两元线性回归方程,前部温度的线性相关性较大;原木楞堆右侧温度与其顶层温度、中层温度、底层温度变化存在三元线性回归方程,中层温度线性相关性最大,上层温度线性相关性最小。利用回归性准确预测整个楞堆温度场变化,对保障林区贮木场的安全生产具有一定的实际意义。

The water mist fire experiments on larch log piles was carried out,and the temperature of each point was obtained during the experiment. Correlation analysis and linear regression analysis on the fixed temperature fields were done by SPSS. The result showed that there was a binary linear regression equation between the changes of the front temperature and the rear temperature and the left temperature of log piles,and the equation was heavily influenced by the front temperature; there was a ternary linear regression equation between the changes of the right temperature and the top temperature,the middle temperature,and the ground temperature; the middle temperature had the greatest influence,and the top temperature had the least influence. The prediction of the stare blankly heap temperature field by using regression method has a certain practical significance to ensure the safety in production of forest timber yard.
