| 摘 要： | 提出了一种通过考察各属性在给定类中取值的相关程度，合并相关程度较高的属性，以提高ＮａｉｖｅＢａｙｅｓ分类方法精确度的改进方法．实验数据表明，在ＮａｉｖｅＢａｙｅｓ方法表现明显不如决策树等复杂分类算法的领域中，这个改进的方法往往能较大地提高了算法精确度

| Abstract: | Through the simulation experiment method, the flame spread characteristics over wood surface in concurrent flow conditions are studied. The flame spread behavior of the wood surface is observed and recorded continuously by using the techniques of flame structure displaying. Then, the flame spread process of the wood surface is inspected and analyzed based on the techniques of the temperature tracing; the flame spread controlling mechanisms of wood pieces in concurrent flow are also analysed. Meanwhile, the temperature and spread rate are obtained of fire propagation of different wood piece surfaces and in different flow conditions, which can be used for build flame spread model. |
