摘要
半定量估算是一种对问题的性质取得一个总体估计的方法。通过半定量估算分析了自由下落水滴的变形和彗木相撞的撕裂效应。论述了半定量估算在简化物理分析、抓住问题本质的意义。
Semi-quantitative estimation,the same as qualitative overall thinking,is one of the important ways to obtain an overall estimation and understanding of the nature of problems in scientific research. By adopting semi-quantitative,this article estimates the deformation of free falling water droplets and the cosmic tear effect of wood collided,thus enhancing the knowledge of the application of semi-quantitative estimation to the scientific research and having an overview of the order of magnitude for the deformation of free falling water droplets.
