At present , the overall tendency of software development is constructing object - oriented , network based , distributed and heterogonous application system using distributed component technologies , and dividing the software system into independent components with different functions , which can be platform and programming language independent , and can communicate with each other for collaboration , handwriting - based identification recognition is an important research field of biometric identification , and also an active topic in computer vision and pattern recognition 目前，软件开发的整体趋势是采用分布式组件技术建立面向对象的、基于网络的、分布的和异构的大规模应用系统，把整个软件系统划分为一个个相互独立的组件，每个组件完成特定的功能，可以跨越多种操作平台，独立于程序设计语言，并且相互通信，协同完成工作。笔迹鉴别是人体生物特征识别中的一个重要研究领域，也是计算机视觉和模式识别领域研究的热点问题。

These concrete works are the following : 1 , a new heterogonous shs model had been proposed , which first included all the relative materials characters , such as reactants particle sizes , changeable heat - conductivity and mass diffusion during shs and so on , and its chemical reaction characters , initial combustion status 具体工作如下： 1 、提出了微观不均匀的燃烧介质模型，在此基础上完成了对非均质燃烧模型数学化的研究，并提出了“燃烧基团”模式，解决了模型数学分析量大的难点。

This new model made a more precise prediction about the shs combustion way and its technological characters possible . 2 , with the heterogonous shs model , lots of combustion way had been imitated by change systems relative factors and the rule of the combustion way change had also been studied , chemical reaction in these systems was controlled by a single mechanism 在该模型中，首次将体系的微观不均匀特性、体系的基本物性及燃烧过程中的化学反应机理与整体燃烧动力学行为联系在一起，从而为更加准确地预测和控制shs体系的燃烧行为，优化shs的工艺过程奠定了理论基础。
