有关“灯泡的非线性伏安特性曲线”的知识概念,上海市物理高考继2004年之后,2006年又推陈出新,再次考查这方面的知识,其目的是检查学生应用物理知识解决实际问题的能力.比较这两年的考题,不同之处在于:①2004年的考题是先已知灯泡的伏安特性曲线,然后再求工作点.2006年的考题是 With regard to the knowledge concept of the “non-linear volt-ampere characteristic curve of light bulbs”, the Shanghai Physical Education College introduced innovations after 2004 and in 2006. The purpose of this study is to examine the students’ ability to apply physics knowledge to solve practical problems. Comparing the exam questions in these two years, the difference lies in: 1) The exam questions in 2004 were the known volt-ampere characteristics of the bulb, and then the work point. The questions in 2006 were
