论文部分内容阅读
读了本刊2004年第1期《一道电磁感应难题的图像巧解》一文和2005年第3期《一道电磁感应难题的巧解》后,很有启发,感触颇多.心中思索着,除了像前一篇文中通过构造v-t图、F-t图,利用v-t图、F-t图与坐标轴间围成的面积的物理意义,结合动量定理和能量守恒定律那样利用图像巧解,和后
After reading the article “Quality of the Image of an Electromagnetic Sensing Problem” in the first issue of the magazine in 2004 and the 3rd issue of “A Solution to the Problems of Electromagnetic Sensing” in 2005, it was very inspiring and quite impressive. As in the previous article, the physical meaning of the area enclosed by the vt diagram, the Ft diagram, and the coordinate axis is constructed by constructing the vt diagram and the Ft diagram, and the image coincidence solution is used in combination with the momentum theorem and the law of conservation of energy.
