In recent years, with the continuous development of society and the continuous improvement of productivity, the requirements of water conservancy and hydropower projects from all walks of life are also constantly improving. This is an infrastructure construction, the quality of the project directly affects the sustainable development of water conservancy and hydropower, but also related to the normal operation of various social production activities. Water conservancy project is closely related to national economic construction and people’s life and property safety. For water conservancy projects, the implementation effect of construction technology and quality control directly affects the construction level. Therefore, in the construction process, we must combine with the actual situation and strengthen the technical quality control, so as to comprehensively improve the construction level of water conservancy projects and ensure the healthy and stable development of China’s water conservancy construction industry.
Water conservancy project construction quality is the top priority of project construction management, and the project quality directly affects the use efficiency of water conservancy project in the future. Because of the complexity of water conservancy project construction in the current society, it not only has a long construction period, but also involves a lot of cross construction content, which has a negative impact on the quality management of water conservancy project construction. Water conservancy project belongs to the project that benefits the country and the people, so we need to pay full attention to the key points of construction technology, innovate construction technology combined with the pace of development of the times, improve construction quality, and ensure the safety of people's lives and property. With the continuous development of society, the number of water conservancy projects is increasing, and the construction technology of water conservancy projects also needs to be improved. The purpose of writing this book is to be able to have a more systematic and scientific water conservancy project construction technology, restrict the construction process of modern water conservancy projects, and improve the technical specifications and engineering scientificity and practicability.

近年来随着社会的不断发展,生产力的持续提升,各界对水利水电工程的要求也不断地提高。这是一项基础的设施建设,该工程质量直接影响着水利水电事业的可持续发展,也关系着各项社会生产活动的正常运作。水利工程和国家经济建设及人民生命财产安全有着密切关系。对于水利工程而言,施工技术和质量控制的实施效果直接影响着施工水平,因此,在建设过程当中必须要结合实际情况,加强技术质量控制力度, 才能全面提升水利工程的施工水平, 确保我国水利建设行业的健康、稳定发展。
水利工程施工质量是工程施工管理当中的重中之重,工程质量直接影响着水利工程日后的运用效率。因为当前社会当中水利工程施工复杂,不仅工期长,而且所涉及很多交叉施工的内容,对水利工程施工质量管理带来了不良影响。水利工程属于利国利民的项目, 需要充分关注施工技术要点, 结合时代发展步伐创新施工技术,提升施工质量,保证人民生命财产安全。在社会不断发展的当下,水利工程数量日渐增多,水利工程施工技术也需要不断提升。撰写《水利工程施工技术》一书的目的也是为了能够一较为系统和科学水利工程施工技术约束现代水利工程施工过程,提升技术规范和工程科学性、实用性。
With the deepening of the concept of new curriculum reform, the dominant position of students is increasingly apparent. Teachers should also pay attention to guiding students to solve problems with new ideas and new ideas in classroom teaching, give full play to students’ self potential, cultivate students’ new thinking quality, make students have innovative thinking consciousness, and comprehensively promote students’ motivation of active inquiry learning.
“Innovation is the soul of a nation and the inexhaustible driving force for the prosperity of a country”. In today’s world, science and technology are advancing by leaps and bounds, and knowledge economy has begun to take shape. The development of education has been closely related to the safety of the country and the rise and fall of the nation. Therefore, it has become an urgent task to cultivate new talents with innovative thinking ability. The cultivation of innovative consciousness and innovative ability is an important task of cross century education. As education itself is a process of innovation, it requires teachers to have a sense of innovation. We mathematics teachers have the responsibility to create a generation of innovative people through teaching. Teachers should excavate the teaching materials, effectively control the teaching materials, introduce new knowledge and new problems that adapt to the development of the times into the classroom, organically combine with the content of the teaching materials, guide students to actively explore, and cultivate students’ innovation ability.
Mathematics is a skill, the crystallization of human wisdom, an important symbol of human civilization, the essence of human being's long-term practice, and the height of the world’s natural laws. Therefore, as long as we learn and think in accordance with its rules step by step, we can definitely learn and understand it.
In a word, mathematics is the use and generalization of natural laws in human labor. It urges people to explore nature, discover the beauty of nature, and make people feel beauty and experience the enjoyment of beauty, so that people can take the initiative to explore and create.

随着新课程改革理念的深入,学生的主体地位日益显现,教师也应在课堂教学中注意引导学生用新理念、新思路去解决问题,充分发挥学生的自我潜能,培养学生全新的思维品质,使学生具有创新的思维意识,全面促进学生主动探究学习的动机。
“创新是一个民族的灵魂,是一个国家兴旺发达的不竭动力。”当今世界,科学技术突飞猛进,知识经济已见端倪。教育的发展已经与国家的安危、民族的兴衰息息相关。因此,培养具有创新思维能力的新型人才,已经成为当务之急,创新意识及创新能力的培养,是跨世纪教育的一项重要任务。由于教育本身就是一个创新的过程,这就要求教师必须具有创新意识,我们数学教师有责任通过教学造就一代有创新精神的人。教师要通过挖掘教材,高效地驾驭教材,把与时代发展相适应的新知识、新问题引入课堂,与教材内容有机结合,引导学生去主动探究,培养学生的创新能力。
数学是一种技能,是人类智慧的结晶,是人类文明的重要标志,是人类在长期的实践中汲取的精华,是世界自然规律的高度。因此,只要按照它的规律,循序渐进的去学、去想,绝对可以学懂。
总之,数学是人类在劳动中对自然规律的利用和概括,它促使人们去探索自然、发现自然之美,使人们从中感受美、体验美的享受,从而使人们主动去探索、去创造。
新生儿期是胎儿的延续,与胎儿和孕母关系密切,因此,新生儿学又是围产医 学的重要组成部分。新生儿各组织器官及其功能尚未发育成熟,而病情变化又非常 快,病死率极高,是最难处理的阶段,要求从事新生儿专业的医务工学工作者具有 丰富的业务知识,精湛的诊疗技术和扎实的专业基础,以降低我国围产儿和新生儿 病死率。 新生儿学是儿科领域中的一个重要组成部分,专业性强,发展迅速。近年来, 新生儿学日益受到重视,一些新的诊疗措施在临床上的应用,使围产期危重儿的发 病率明显减少,提高了新生儿疾病的救治率及生存质量。并随着现代医学和生命科 学的不断进步、新技术和新理论的不断涌现,儿科学在疾病诊疗方面也取得了跨越 式的发展,越来越科学化、细致化、专业化。这就要求儿科医师既要掌握理论知识, 熟悉常见病、多发病的诊治,又要不断扩宽视野,将最新的技术成果应用于临床工 作中,才能更好地为患者服务。
