These concrete worksare the following:1, a new heterogonous SHS model had been proposed, which first included all the relativematerials characters, such as reactants particle sizes, changeable heat-conductivity and massdiffusion during SHS and so on, and its chemical reaction characters, initial combustion status.This new model made a more precise prediction about the SHS combustion way and itsTechnological characters possible.2, with the heterogonous SHS model, lots of combustion way had been imitated by changesystems 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。2、采用非均质燃烧模型，通过对相关参数的改变，模拟SHS燃烧过程中的各种燃烧行为，并研究了燃烧行为变化的规律。

Considering a spherical porous carbon particle immersed in a static ambient atmosphere, the combustion characteristics under three basic conditions: frozen flow, equilibrium flow, partial flow are solved in a half-analytical and half-numerical way. By using the LAEA (Large Activation Energy Asymptotic Method), the departure value of some parameters such as combustion rate, temperature, and concentration are obtained. On this basis, the rules of a carbon particle combustion under various conditions when the gas phase Damk〓hler number is in the range of 0,+∞ are summarized.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
