A new method for computer dynamic simulation of cylindrical gear cutting process isproposed, in which cutting deviation is introduced directly into simulation equations for the firstbine. A Programme is written in Turbo C, with which cylindrical gear cutting process can be shownclearly, in addition,the mathematical model determining all tooth surfaces for gear TCA and stressanalysis and contacted dynamics analysis can be obtained automatically. 提出了一种新的滚刀加工渐开线型圆柱齿轮的计算机仿真方法,首次将加工误差引入仿真方程,并用TurboC开发了仿真软件,可以逼真、清晰地模拟出齿轮加工的详细过程.该方法能为齿轮的TCA、接触应力分析和振动分析等自动生成科学的有限元网格计算模型. Generativism and Constructivism are the two different ways to do the research on system theory at present.The author advocates the departure from the new natural viewpoint,to explore the world's evolution and build up the “Generative Science”.And presents the “Origin of Generation”as the new scientific starting line of the logic,the differences between the “Origin of Generation”and“Atom”are:1.“Origin of Generation”is the integrity without being divided,it's not the basic element.2.“Origin of Generation”could... Generativism and Constructivism are the two different ways to do the research on system theory at present.The author advocates the departure from the new natural viewpoint,to explore the world's evolution and build up the “Generative Science”.And presents the “Origin of Generation”as the new scientific starting line of the logic,the differences between the “Origin of Generation”and“Atom”are:1.“Origin of Generation”is the integrity without being divided,it's not the basic element.2.“Origin of Generation”could be created and declined,it's a process substantially.3.“Origin of Generation”demonstrates first the“efficient cause”and“final cause”,not“material cause”.4.Parts are generated by disintegrating and growing,with the character of whole and fractal.5.It is information,not the atom quality which decides the system growing.In the end,the author discussed the differences between the current Generativism and Darwin's evolutionism. 当前 ,构成论和生成论是系统研究中的两条不同道路。作者主张从新的自然观出发 ,创建探索世界生成演化的“生成科学”。并提出以“生成元”作为这一新科学的逻辑起点 ,生成元与“原子”的根本差别在于 :1、生成元是未分化的整体 ,不是基本构成部分 ;2、生成元可生可灭 ,本质上是过程 ;3、生成元首显“动力因”和“目的因” ,而非质料因 ;4、部分由分化生长而成 ,具有整体性和分形性 ;5、决定生长的是信息 ,而非载体的原子质量。最后对当代生成论与达尔文进化论作一大略的比较。 On the basis of analyzing the drawbacks of our country's current land assembly,the article made a further speculation on how to structure a new-type land assembly,and put forward the new idea of the construction on a new land assembly at the basis of the following five aspects:standing the right of national land assembly,perfecting the property relations of rural collective land,exploring the scientific mechanism in the land compensation,confirming rationally the way of peasants' placing whose land are collected,and...
