爱迪生(如图1)是伟大的发明家,他一生中曾获得1093项发明专利,这一成就的获得与他那科学、灵活、具有创造性的思想方法有重要的关系.据说,有一天,爱迪生叫他的助手们测灯泡的容积彳艮长时间没有一个人来报告结果.他走过去发现助手们一个个都忙得不亦乐乎,有的在画图,有的在做着高等数学运算.爱迪生笑了笑,在灯泡中装满了水,再将灯泡中的水全部倒入量筒中,测出量筒中水的体积也就得到了灯泡的容积.爱迪生在测量时用到了一个重要的物理方法——转换法,它是将不容易直接测 Edison (pictured in Figure 1), a great inventor, has won 1,093 invention patents in his life, and this achievement has an important bearing on his scientific, flexible and creative ways of thinking and thought. One day, Edison He told his assistants to measure the volume of the light bulb, and for a long time nobody reported the result.He walked over to find that aides were overwhelmed, drawing and some doing advanced math. Edison smiled and filled the bulb with water, poured all the water in the bulb into the measuring cylinder, measured the volume of water in the measuring cylinder, and obtained the volume of the bulb.Edison used an important physical Method - Conversion method, it will not be easy to measure directly
