关于电功及电功率的教材,在与学习苏联电力化的物理原理有关的知识范围中,占有重要的地位。这些概念的理解、关于它们的量度单位的清楚的观念以及进行有关的简单计算的技能应该是综合技术教育的必要组成部分。可惜,在七年级的物理教科书中,这个学习材料的叙述是形式的、干燥的、很简单的,并且从 Textbooks on electrical and electrical power play an important role in the range of knowledge related to studying the physical principles of Soviet electrification. The understanding of these concepts, the clear ideas about their units of measurement and the skills to make relevant simple calculations should be an essential part of integrated technical education. Unfortunately, in the seventh grade physics textbook, the narrative of this learning material is formal, dry, very simple, and from
