摘要
从光的折射定律出发，运用有关数学知识，定量研究了水中物点成像的规律．得到了观察者自坐标原点ｏ出发沿ｘ轴正向改变观察方位观察时所看到虚像连成的曲线方程和观察者在圆柱体形装水容器上空附近不同方位观察时水中物点Ａ成像的区域，并且利用计算机描绘出了其曲线与成像的区域．
According to the refraction law of the ray and with some knowledge of maths, the author quantitatively analysed the regularity of image of the mini-object in the water. Then not only a series of curve equation to the virtual image link are obtained when the observer changes the position of observation to see along X Line from the direction of point O, but also the area of the image in the water are obtained when the observer observes from different divections near the above of .the column container. And the curve and the area of image are described by the means of computer.
