This paper simulate oxidation - deoxidize reaction , o enzyme catalysis and the origin of life . the stella mode of oxidation - deoxidize reaction can help student understand chemistry reaction in integer , train student understand correlation from the all and the one . stella simulation help us to research enzyme catalysis promoter stable state former dynamics , and to observe the basic measure of the whole response or some response directly , and offer effective datum that can be used to analysis complicated response mechanism , because of too many relevant disputes of origin of life , to introduce student various kinds of theories maximally , we use stella software to imitate , strive to give students the ultimate thinking space , make them to be able to verify their idea in the models . in this course , teachers and students can observe the result and test the theory through simulation , learn what to happen when the former hypothesis and scene changed , and turn the study way of infusing and absorbing into discussion study , make study especially thinking ability of student get improvements by a large margin 氧化还原体系的stella模型能使学生对复杂的化学反应有整体理解，培养学生从整体的角度理解各种物质间的相互作用联系； stella帮助我们对酶催化反应稳态前动力学进行研究，可以直接地观察整个反应的基本步骤或局部反应，提供可用于分析复杂反应机制的有效数据； stella创建的生命起源的模型，力争给学生最大的思维空间，使他们可以在模型中验证他们的想法，在此过程中，教师和学生可以通过模拟以试验理论、观察结果，并学习到原有假设或情景改变时会有什么情况发生，将灌输性、吸收性的学习方式变为讨论式学习，使学生的学习特别是思维能力得到大幅度的提高。
