摘　　要：函数极限的求解是高等数学这门课程中的一个重要知识点,根据题目的难易程度将limf(x) x→x_0型函数极限的求解分成五种类型:①利用函数的连续性求解;②利用恒等变形求解;③利用两个重要极限及无穷小量的知识求解;④利用L′Hospital法则求解;⑤综合运用.Solution of the type of function limit is very important part in higher mathematics. According to the difficulty of the questions, the type is divided into five ones： the continuity of functions to solve, the use of the identical deformation, using the knowledge of the two important limit and dimensionless solution, the use of L ＂Hospital law to solve and the comprehensive use.

关 键 词：limx→x0f(x)型函数极限 求解方法 L'Hospital法则
