绝对不等式-
运用曲线族的模和环模等工具，结合Rohde定理，证明同胚为双Lipschitz映射的充要条件是：它适合环的对数绝对值不等式；
By applying the tools such as modulus of curves and rings , together with Rohde 's theorem , it proves that a homeomorphism is a bi Lipschitz map if and only if it satisfies a logarithmically absolute value inequality of rings .

含有绝对值的不等式这一节采用这种方法，充分发挥了教师的诱导作用，激发了学生主动学习，善于思索，开动脑筋的积极性。
This section " inequality with absolute value " is based on this teaching method , in witch the teacher is able to give full play to his function of guiding and motivate the students to active study and deep thinking .
