2006年江苏高考物理卷的压轴题是一道以电磁感应为载体的力电综合题,涉及变加速运动过程的处理,必须应用微元法巧妙求解,难度比较大,绝大多数考生对该题很不适应.其实这并不是一道全新的命题,而是一道推陈出新的佳题.在这里就该命题的陈题到新题的演变及破解方略作一解读.图1[ In 2006, the final issue of the physical volume of the Jiangsu college entrance examination was a power and electricity problem with electromagnetic induction as the carrier. It involved the processing of the variable acceleration process and must be solved with the microelement method. The difficulty was relatively large. The vast majority of candidates were very concerned about this problem. Inappropriateness. In fact, this is not a new proposition, but a new topic. It is here that there is an interpretation of the evolution of the proposition from the title of the proposition to the new problem and the interpretation of the strategy. Figure 1 [
