Professor Liao Shantao is an outstanding mathematician in China. As a result of his profound and systematic research work, he won the Mathematics Prize in 1985 which was the first time awarded by the Third World Academy of Sciences for his contributions to differentiable dynamical systems and other fields. He also won first-class award of National Natural Science Prize of China in 1987, The Chinese edition of this book collects eight of his major articles on differentiable dynamical systems in the period of 1963 - 1984, arranged in the order according to the dates of submission for publications, together with a preface and an appendix written also by him. Other two appendices A and B, which are original articles by Liao, are added to the translation to the English edition. .

This book introduces systematically the derivation of the two fundamental notions of "standard systems of differential equations" and "obstruction sets" and exhibits their important properties and applications to stability problems.

  首先感谢百花文艺出版社在浩瀚的书籍海洋中发掘出十多年前只印了三千册的这本书，建议我将书再版。

  这部《中国相声史》是在王决老师的《相声行内轶闻》等著作的基础上，汪景寿老师从学术角度系统化，由我们三人整理和编写，1995年由北京燕山出版社出版的。王决老师和汪景寿老师都是中国相声界和曲艺界德高望重的理论家。当时的我是北大中文系研究民间曲艺专业的硕士研究生，在汪老师的指导下研究相声。作为研究的一个环节，老师让我参加这本书的部分写作。在调查整理和写作的过程中，我跟二位老师学到了很多东西，与其说我是作者中的一个，不如说是这本书的第一个热心读者。遗憾的是当时的我年轻不懂事，没能真正认识和珍惜与二位老师在一起的那么好的学习机会。现在他们都走了，我没来得及报答，至今也没能如他们所期望的那样成为中日曲艺文化交流的桥梁，辜负了他们的厚爱，实在太惭愧了。这次百花文艺出版社帮我做了一个小小的弥补，真是感激不已。

  百花在北京找我谈再版是2011年2月底的事，之后我就回国了。不久就遇到了东日本大地震。虽然东京的灾情不严重，可想到重灾区东北的情况很是心痛。因为灾情太大，加上核电站发生事故，官方和红十字会没能马上采取具体的救灾措施，大家都为此着急的时候，一对出身东北的年轻漫才艺人站出来，展开了以“东北魂”命名的草根活动（日本的漫才是类似对口相声的演艺形式）。原来他们在地震发生的那几天正在东北地区演出，地震当天也是在避难所和当地人一起过的夜。想到那时在剧场和他们共享欢乐时刻的观众们如今在灾难中不知死活，很是坐立不安，就通过自己的博客描述他们亲眼所见的灾情及灾民们的情况，告诉人们目前灾民们最需要什么。回到东京后，他们通过博客和媒体继续呼吁人们捐款捐物，参加志愿活动。全国的漫才迷特别是年轻人及时响应号召，开始展开各自力所能及的救援活动。那对漫才艺人好比灾区和全国之间的桥梁，他们在全国义演集资，然后和伙伴们一起带着救援物资和食品等到灾区慰问。“东北魂”慢慢形成了一股不小的民间救援力量。由一对年轻漫才艺人发起的行动为什么后来有了那么大的号召力呢？因为人们觉得漫才是最贴近生活的一门艺术，反映普通人的喜怒哀乐，通过幽默风趣的语言把活生生的人展现在人们面前。人们笑的是可笑、可爱、可悲的剧中人，同时笑自己身上一样存在的可笑、可爱、可悲的因素。所以人们觉得漫才艺人的话真实可信，比起大人物的大道理更有说服力。笑的艺术的力量就这么伟大。相声不也一样吗？我之所以喜爱相声艺术，也是因为这一点。

  《中国相声史》出版不久，中国相声界经历了一段比较寂寞的时代。人们关注更多的是小品，我们相声爱好者因很少能听到和看到相声而发愁。而近年来，随着小剧场文化的发展又给予相声广阔的天地，带动起大量年轻的艺人和观众，迎来了又一股相声热，有时还为今天到哪个相声场子去听相声而头疼呢。王决老师和汪景寿老师如果看到了这样的相声盛况，一定会非常高兴的，可惜他们已经不在了。《中国相声史》新的篇章就等着年轻的一代去写吧。我也期待着！

  在旧版和新版的出版过程中，我们得到了中国艺术研究院的包澄洁老师、蔡源莉老师以及各位中国曲艺界人士的帮助和支持，在此深表感谢！最后，特别感谢编辑耐心等待懒惰迟笔的我把这篇序文写完。
