本文讨论等壁厚锥管悬臂梁挠度计算时的微分法和差分法，得到了概念清晰、表达简洁的计算公式，并辅以实例对比两种方法之差异。%In this paper,the differential method and difference method for calculating deflection of a cantilever beam with equal wall thickness tube are discussed. And it then gets a calculation formula of clear concept and concise expression,and adds a example to compare the differences of the two methods.
