Appendix Common Graphical Symbols for Hydraulic and Pneumatic Components (GB/T786. 1-93) The 11th Five-Year Textbook of Mechanical Engineering in Colleges and Universities organized by National Defense Industry Press will be published soon, and I am glad to preface it.

With the development of national economy and society, China's higher education has formed a good situation of popular education. In order to meet the huge demand of building an innovative country, it is urgent to cultivate high-quality professionals and innovative talents. Schools must respond quickly to educational ideas and teaching ideas and carry out in-depth teaching reform. One of the main contents of teaching reform is curriculum reform and construction, including the reform and construction of teaching materials, which should be embodied and solidified in teaching materials.

Teaching materials are an indispensable part of teaching, and the level of teaching materials will directly affect the teaching quality, especially the cultivation of students' innovative ability. As a teaching material of mechanical engineering, we should not only impart basic theoretical knowledge, but also emphasize theory and practice, emphasizing the combination of theory and practice, and cultivate students' ability to solve practical problems and innovate. With the deepening of the new round of teaching reform, the establishment of the new curriculum system and the development of curriculum content, the task of building such a new set of teaching materials has been placed in front of us urgently.

This set of "Eleventh Five-Year" Textbooks of Mechanical Engineering in Colleges and Universities, organized by National Defense Industry Press, is just the right time. The characteristics of this set of teaching materials are "helping to improve students' innovative ability and knowledge level", rigorous and scientific topics, advanced, innovative and practical, focusing on the cultivation of students' ability as the principle, compiling characteristic teaching materials and excellent teaching materials as the guiding ideology, paying attention to the three-dimensional construction of teaching materials and working hard on the teaching material system. In the process of compiling, each textbook has been carefully compiled by the editor-in-chief and editors and strictly checked by the presiding experts, which makes this textbook not only inherit the characteristics of the old textbooks, but also adapt to the requirements of educational reform under the new situation, ensure the systematicness and quality of the textbooks, embody the teaching concepts of innovative education, ability education and quality education, effectively stimulate students' autonomous learning ability, improve students' comprehensive quality and innovative ability, and serve the cultivation of outstanding talents who meet the needs of society. The publication of series promotes the construction of teaching materials in colleges and universities, especially the construction of excellent courses and their teaching materials.
