Energy is the material basis for the survival and development of human society, and its importance is self-evident. The increasingly prominent problems of energy shortage and environmental pollution greatly enhance the status of new energy and renewable energy in the field of energy. Solar energy, wind energy, water energy, biomass energy, geothermal energy, marine energy and other energy technologies have also developed rapidly in recent years. In order to overcome the difference between energy supply and energy demand in time and space, it is necessary to use certain methods, through certain media or devices, to directly or indirectly convert one form of energy into another form of energy for storage, and release it when energy is needed. Energy storage technology is a variety of methods to study energy storage.
         The traditional power system, which is a real-time balance system formed by a set of generation side variables and a group of power consumption side variables, has the characteristics of instant generation and use. There are generally large peak valley changes in the load on the power side, which brings great pressure to the power generation side and causes many disadvantages of the power system. By using energy storage technology, the surplus power can be stored and sent out at an appropriate time, so as to realize the function of energy storage “regulation, optimization, efficiency increase and protection” in the power system. This can make the power distribution flexible, optimize the system resource allocation, improve the operation efficiency and ensure the stable operation of the system. The development of energy storage technology is to ensure the continuous process of energy utilization. It is very important in human daily life and industrial production, such as electric power industry, new energy vehicles, solar thermal utilization and other fields, and it is of great significance to promote the sustainable development of energy.

能源作为人类社会生存和发展的物质基础，其重要性不言而喻。能源短缺和环境污染等问题的日益突出，极大地提升了新能源和可再生能源在能源领域的地位。太阳能、风能、水能、生物质能、地热能、海洋能等各种能源技术近年来也得到快速发展。为克服能量供应和能量需求在时间和空间上的差别，就需要采用一定的方法，通过一定的介质或装置，将某种形式的能量直接或间接转换成另一种形式的能量储存起来，在需要用能的时候释放出来。研究能量储存的各种方法，即储能技术。
       传统模式下的电力系统，即一组发电侧变量和一组用电侧变量所形成的实时平衡的系统，具有即发即用的特点。用电侧负荷普遍存在较大的峰谷变化，给发电侧带来了较大压力，造成了电力系统的诸多弊端。利用储能技术可以把多余的电力储存起来，在适当的时刻再发出去，从而在电力系统中实现储能“调节、优化、增效、保护”的功能，使电能灵活分配，优化系统资源配置，提高运行效率以及保障系统稳定运行等。储能技术的发展，是为了保证能量的利用过程能够连续进行，在人类的日常生活和工业生产等各方面，如电力工业、新能源汽车、太阳能热利用等多个领域，都非常重要，并对促进能源的可持续发展具有重要意义。

With the improvement of people’s living standards, the requirements for housing construction are constantly improving. From an objective point of view, in the current housing construction, the foundation engineering is a decisive component, which will affect the construction results of the project in many aspects, such as the service life of the house, the living environment and office efficiency. For this reason, in the future, housing construction must choose reasonable foundation engineering construction technology in many aspects according to objective needs, complete the soundness of the technical system and the improvement of the construction level, so as to provide more help for housing construction.
        As the population continues to increase, the demand for housing has been much higher, so housing construction projects have been the focus of the society. Housing construction belongs to the people’s livelihood project and also has an important impact on the national economy. Construction engineering will use a lot of construction technology, but in the actual construction process, there may be some technical problems that affect the quality of the project. In the process of house construction, foundation engineering is a very important link. As the foundation of the house, the safety and stability of the foundation are directly related to the security of lives and property of the people.
        Foundation engineering has always been a very important part of housing construction projects. It will not only directly affect the quality of the housing construction, but also affect its safety and stability in use. Therefore, this book analyzes the construction technology and inspection of the foundation engineering of housing construction to provide an effective guarantee for the construction quality.

随着人们生活水平的提高，对房屋建筑的要求也在不断地提升。从客观的角度来分析，当前的房屋建筑当中，地基基础工程是决定性的组成部分，且在很多方面都将影响到工程的施工效果，并且在很多方面，都将导致房屋的使用寿命、居住和办公效果受到极大的影响。为此，在今后的房屋建筑当中，必须根据客观的需求，在多方面选择合理的地基基础工程施工技术，完成技术体系的健全和施工水平的提升，为房屋的建筑提供更多的帮助。
        随着人口不断增多，人们对房屋的需求量越来越高，因此房屋建筑工程开始受到社会的关注。房屋建筑属于民生工程，对国民经济也有着重要影响。建筑工程会使用到大量的施工技术，但是在实际施工过程中，可能会存在一些技术问题影响工程质量。在房屋建筑过程中，地基工程属于其中非常重要的环节，作为房屋的基础，地基的安全稳定性直接关系到人们的生命财产安全。
        地基基础工程一直以来都是房屋建筑工程项目在施工过程中非常重要的一部分，不仅会直接影响到房屋建筑的施工质量，而且还会影响到其在后期使用过程中的安全性和稳定性。因此，本书针对房屋建筑地基基础工程的施工技术与检测进行分析，为施工质量提供有效保障。

With the continuous development of social economy, China’s water conservancy construction has made further development. As an important part of water conservancy infrastructure project, hydrology and water resources survey plays an important role in promoting the sustainable development of hydrology. Therefore, it is of great significance to strengthen the research of hydrology and water resources survey.
      Due to the different living habits, living standards and climatic conditions, people’s domestic water demand is very different. With the improvement of living standards, especially the large-scale construction of modern cities, the water consumption of urban residents is increasing day by day. With the rapid development of industry, agriculture and urban construction, the demand for fresh water is growing rapidly. More and more industrial wastewater and domestic sewage will be produced, and a considerable amount of wastewater will be directly discharged into the nearby water body without reasonable treatment, causing serious pollution to water resources. The hydrogeological survey provides hydrogeological data for the design of engineering projects and the formulation of national economic development plan. Hydrogeological survey is a project with the basic theory of hydrogeology as the guiding ideology, which studies the methods and theories of hydrogeological survey. The optimization of hydrogeological survey is conducive to the improvement of survey quality and the stability of the project. In order to promote the stable operation of engineering survey, we should do a good job in hydrogeological survey, which provides a theoretical basis for effectively solving hydrogeological problems.

In recent years, with the increasing investment in power infrastructure projects in  China, we must implement effective management of complex infrastructure business  through information system. The enterprise resource planning (ERP) is an advanced  management idea, which focuses on organization model, business process, enterprise rules  and regulations, information technology, etc.  

       Power engineering management is an important part of power enterprise  management in China, and plays an indispensable role in the power system. The  management of electric power project has an important influence on the economic benefits  of project investors and construction enterprises. In recent years, with the implementation  of China’s sustainable development strategy, the construction of power engineering  projects is gradually increasing. For China’s power grid, under the premise of ensuring the  improvement of the power grid system and power supply quality, the reasonable cost  control can not only improve China’s economic level, but also help China’s power grid  system to be more mature and perfect. At present, the high project cost is largely due to the  unscientific and unreasonable management mode of power grid system. Therefore, if we  want to control the project cost, we should start from the perspective of management.

近些年来，伴随着我国在电力基建工程上投资的日趋增加，我们必须要通过信息系统，来对繁杂的基建业务实施有效的管理。而企业资源计划，它是集中了组织模型、业务流程、企业规章制度以及信息技术等，其在管理思想上比较先进。 电力工程管理是我国电力企业管理工作的重要组成部分，在电力系统中发挥不可或缺的作用。

        电力工程管理工作对工程投资主体的经济利益、施工企业的经济效益有着重要的影响。近年来，随着我国可持续发展战略的实施，电力工程项目的建设也逐渐增多。对于我国电网而言，在保障电网体系的完善和供电质量的前提下，最大限度地合理控制造价成本，这不但能够提升我国的经济水平，而且有助于我国电网体系更加成熟完善。当前，工程造价过高很大程度上是因为电网体系的管理模式不科学不合理，因此若要对工程造价进行控制，那么就应当从管理这一角度来着手解决。
