等效平衡知识点是教学的一个难点,也是高考的热点。同学们对“等效平衡”的含义、建立条件、规律以及应用,普遍感到难以接受与理解,更谈不上运用。理解概念、巧设过程能有效突破等效平衡,其他非等效平衡及平衡移动问题,都可通过等效思维方式进行分析和解决。 Equilibrium balance knowledge is a difficult point in teaching and is also a hot spot for college entrance examinations. Students generally feel that it is difficult to accept and understand the meaning, establishment conditions, laws, and applications of “equivalent balance”, let alone use it. Understanding the concept and skillful process can effectively break the equivalent balance, and other non-equivalent balance and balance movement problems can be analyzed and solved through the equivalent thinking mode.
