我们中等学校教师在给初中三年讲化学时,无论用的是东北出版社的本子,或人民教育出版社的本子,都能遇到定比定律的讲解(东北出版社的本子是在第七章,人民教育出版社的本子是在第五章)。在给学生贯彻这个定律的概念时,首先让学生亲自观察实验的结果得出结论,这是由具体到抽象的教学原则所不可缺少的。所以给吕萨克实验对讲解定比定律来说是很重要的了。但给吕萨克的原装置(即用带白金极的一端封闭的有刻度的爆气管,和高倍
When our middle school teachers talked about chemistry for junior middle school for three years, no matter using the book of Northeast Press, or the book of People’s Education Press, they all can encounter the explanation of fixed law (the book of Northeast Press is in the seventh Chapter, People’s Education Press book is in Chapter V). When implementing the concept of the law to students, first let the students observe the result of the experiment to draw conclusions, which are indispensable to the teaching principle of the specific abstract. So it is important to give Lussac experimental interpretation. But to Lussac’s original device (that is, with a platinum pole closed end of the scale of the blast tube, and high times
