Vocal teaching is an important part of vocal music pedagogy. In the process of vocal teaching practice and theoretical research, it can also be an independent subject. The course of vocal music is an important compulsory course for vocal music schools (departments) in colleges and universities. Its basic tasks are:

1. To enable students to master the basic knowledge and theory of vocal music education, understand the objectives and requirements of vocal music education in colleges and universities, love vocal music education, and establish professional ethics and sense of responsibility for vocal music education.

2. To make students master the basic principles and methods of vocal music teaching in colleges and universities, understand the basic process and teaching content of vocal music teaching, and lay a solid foundation for educational practice and vocal music education in the future.
      3. Let students learn and understand the famous foreign vocal music teaching system and teaching methods, and broaden the vision of vocal music education.
    4. Let students integrate their professional knowledge and skills, and make them become a comprehensive ability, that is, the ability to engage in vocal music education in colleges and universities.
    Music pedagogy is an interdisciplinary subject of musicology and pedagogy. This subject not only follows general laws of pedagogy, but also has some characteristics of music itself. No matter how the connotation and extension of music education change, the fundamental purpose of music education is to make music education practice well developed. And a good music education must have teachers who carry out the education, students who have the purpose of learning and the media, music, which connects teachers and students, which are the three parts of music education activities. Music education will not exist with any of teachers, students and music. China’s professional music education has a certain scale, and music pedagogy is an inevitable subject when the era develops to a certain stage. It is more specific than general pedagogy, and more emphasis on discipline.
    Compared with music teaching method and music teaching theory, the problems it studies are more universal, wider in scope and higher in theoretical level. Music pedagogy plays an irreplaceable role in training talents who can adapt to the future social development and have forward-looking music education thoughts.

声乐教学是声乐学科教育学中的一个重要组成部分，在声乐教学实践和声乐教学理论研究过程中，它又可以是一个独立的学科。高校声乐课程是高等院校声乐院（系）的重要必修课。其基本任务是：
  1. 使学生掌握声乐教育的基础知识和基本理论，了解高校声乐教育的目标和要求，热爱声乐教育事业，树立起从事声乐教育的职业道德观和责任感。
  2. 使学生掌握高校声乐教学的基本原则和基本方法，了解高校声乐教学的基本过程和教学内容，为进行教育实习和今后从事声乐教育工作打下扎实的基础。
  3. 让学生学习、了解国外著名声乐教学体系和教学方法，拓宽声乐教育视野。
  4. 让学生将所学的专业知识和专业技能技巧融会贯通，使其成为一种综合能力，即从事高校声乐教育的能力。
  音乐教育学是音乐学和教育学的交叉学科。这一学科既遵循教育学的普通规律，又具有音乐艺术本身的一些特点。无论音乐教育的内涵和外延怎么改变，音乐教育的根本目的是使音乐教育实践能够得到良好的开展。而良好的音乐教育必须有实施教育的教师、有学习目的的学生和联系教师和学生之间的媒介——音乐，这是音乐教育活动的三个部分，缺一不可。教师、学生、音乐三个要素缺了其中任何一个要素，音乐教育都不能存在。我国的专业音乐教育已具有一定的规模，音乐教育学是时代发展到一定阶段时必然产生的学科。它比普通教育学更加具体化，更加注重和强调学科性。它所研究的问题比音乐教学法和音乐教学论更具有普遍性，范围更广，理论层次更高。音乐教育学对培养能够适应未来社会发展的、全面的、具有前瞻性音乐教育思想的人才发挥着不可替代的作用。

In today’s society, competition between enterprises is becoming increasingly fierce. Facing the actual situation, in order to be able to develop continuously and healthily in the fierce competition, enterprises can only regard talents as their core competitiveness, and become a powerful weapon to improve efficiency and ensure their own competitive advantages.

With the acceleration of the global warming process and the shortening of the global abnormal climate occurrence cycle, sustainable development has attracted the attention of the whole world in today's population expansion, the destruction of the earth's environment, the depletion of resources and other issues. People began to reflect on the increasing development of construction projects. In the one hundred years since the Industrial Revolution, the construction industry has a great impact on the environment.
    The construction industry is a “big energy consumer”. 50% of the global energy consumption lies in the building, and the energy consumption of HVAC accounts for 30%~50% of the building energy consumption, and increases year by year with the improvement of people's requirements for the quality of life. In the process of sustainable design, under the influence of various financial crises and energy crises, people reduce the energy consumption of buildings by reducing the fresh air volume, reducing the operation power of air conditioner, reducing the air volume of circulating fans and other measures. However, while reducing energy consumption, it also reduces people's comfort level to the lowest limit. Energy consumption has decreased, but new problems have arisen and air quality is deteriorating. With the development of the construction industry, people's awareness level is constantly improving. HVAC professionals gradually understand that energy conservation and environmental protection should be organically unified. Therefore, with the minimum energy consumption, creating a healthy and comfortable indoor environment and protecting the atmospheric environment is exactly the requirements of the new building for HVAC specialty. HVAC equipment is a huge and complex system engineering. As professional HVAC technicians, we must strictly grasp each process to ensure the normal use of the building's HVAC system.
    The main content of this book includes: HVAC system, HVAC cold and heat sources, HVAC energy saving technology, HVAC system and equipment control energy saving, HVAC system automatic control and noise isolation, HVAC construction and installation basic knowledge, central heating equipment construction and installation process, HVAC engineering construction and installation process, refrigeration pipeline and equipment construction and installation worker, operation and commissioning of ventilation air conditioner and refrigeration system and anti corrosion and heat preservation of HVAC system. 

This book can be used as a standing reference book and training book for staff of heating and ventilation engineering cost and relevant work, and also for teachers and students of relevant majors in vocational colleges.

    In the process of compiling this book, many excellent books and relevant national standards have been referred to and used for reference, and the help of relevant staff has been obtained. Due to the limited knowledge and experience of the author, although the editor tries his best, there are still some omissions in the book. Experts and readers can criticize and correct them and it will be appreciated very much.

随着全球变暖进程的加速和全球异常气候出现周期的缩短，在人口不断膨胀、地球环境被破坏、资源枯竭等问题困扰今天的人类，可持续发展已经引起全世界范围的关注。对于开发力度不断加大的建筑工程，人们也开始进行反思。自工业革命之后的短短一百年间，人类所从事的活动中，建筑业对环境产生了巨大的影响。
  建筑业是个“耗能大户”，全球能耗的 50%在于建筑，而暖通空调能耗占建筑能耗的 30%～50%，并且随着人们对于生活质量要求的提高而逐年增加。在可持续设计的过程中，在各种各样金融危机、能源危机的影响下，人们以减低新风量，减小空调运行功率，降低循环风机风量等措施来降低建筑的能耗。但是，在能耗降低的同时，也把人们的舒适程度降低到了最下限。能耗下降了，但新的问题又产生了，空气品质在不断恶化。随着建筑业的发展，人们的认识水平不断提高，暖通专业人员逐渐明白，要把节能和保护环境有机地统一起来。因此，以最少的能耗，创造健康、舒适的室内环境，并保护大气环境， 这也正是新型建筑对暖通专业的要求。
  暖通空调设备是一个庞大而复杂的系统工程，作为专业的暖通技术人员，必须严格把握好每道工序，保证建筑物的暖通系统正常使用。
  本书主要内容包括：暖通空调系统、暖通空调冷热源、通风节能技术、暖通空调系统与设备控制节能、暖通空调系统的自动控制和消声隔振、暖通空调施工安装基本知识、集中供热设备施工安装工艺、通风空调工程施工安装工艺、制冷管道和设备施工安装工、通风空调及制冷系统运转调试、暖通空调系统防腐与保温。
  本书可作为从事暖通工程造价及相关工作人员的常备工具书和培训用书，也可供职业院校相关专业的师生参考使用。
  本书在编写过程中参阅和借鉴了许多优秀书籍和有关国家标准，并得到了相关工作人员的帮助，在此一并致谢。由于作者的学识和经验有限，编者虽尽心尽力，但书中仍难免存在疏漏或未尽之处，敬请有关专家和读者予以批评指正。
