论文部分内容阅读
第2版《初中物理》第一册第一章《天平》一节课文中,关于托盘天平的构造,图中只标出4为横梁,B为指针,E为调节螺母,K为刻度线,致于底座、横粱上的标尺、游码、天平盘等,图中并未标出。再则,物理课本上与化学课本上关于托盘天平的构造名称也不统一。例如:物理课本上(22页),把K叫刻度线,化学课本上(233页图中)则叫标尺;物理上把附在横梁上的叫标尺,而化学上叫刻度尺。这样编排,不利于学生自己阅读课文,而且造成了不同学科间的不一致,师生无所适从。
In the second edition of “The Physics of Junior Middle Schools”, the first chapter of the “Balance” section of the text, regarding the construction of the tray balance, only 4 beams are marked in the figure, B is a pointer, E is an adjustment nut, and K is a tick mark. Due to the base, the scales on the rails, the rider’s code, balance plates, etc. are not shown in the figure. In addition, the structural names of the tray balances in the physics textbooks and chemistry textbooks are not uniform. For example, on the physical textbook (page 22), K is called the tick mark. On the chemistry textbook (page 233), the scale is called; physically attached to the beam is called the ruler, and chemically called the scale. This layout is not conducive to the students to read the text, but also caused inconsistencies between different disciplines, teachers and students are at a loss.
