论文部分内容阅读
基础物理教材和有关的科普书籍等,涉及原子核裂变反应或介绍原子反应堆等问题时,大多附有示意图(见图1或图2),以直观、形象地说明中子链式反应等.认真地阅读、思考这类经典的示意图,我们发现它存在点问题,即不全面、有缺漏与遗憾,它还不是中子链式反应的“写真”和全息图,这类图不利于学生等正确地了解、认识原子核裂变反应及基本过程等.
Basic physics textbooks and related science books, etc., involving nuclear fission reaction or introduction of atomic reactors and other issues, mostly attached to the schematic (see Figure 1 or Figure 2), to visually and vividly illustrate the neutron chain reaction, etc. seriously Reading and thinking of such classic diagrams, we find that it has some problems, that is, incompleteness, omissions and regrets. It is not yet a “photo” and hologram of neutron chain reaction. Such graphs are not good for students, etc. Correctly understand and understand the nuclear fission reaction and the basic process.
