Chemical production is an important pillar of economic and social development. On the one hand, chemical production has effectively promoted the development of national economy and improved people’s living standards; on the other hand, there are many unsafe factors and occupational hazards in the production process of chemical industry (especially dangerous chemicals), such as flammable, explosive, toxic, high temperature, high pressure, corrosion, etc., so it has greater potential risk than other industrial production. In the process of chemical production, risk exists objectively. Although it is invisible and intangible, it is closely related to production activities.
    Starting from strengthening the training and adjustment of safety production technology for chemical workers, this book systematically analyzes various risk factors in the process of chemical production according to the working principle of “safety first, prevention first, comprehensive treatment”, using the basic principles and methods of chemical industry and combining with the characteristics of chemical safety production. The possibility and severity of accidents or occupational hazards are predicted, and scientific, reasonable and feasible safety production prevention measures and control methods are put forward. It takes chemical production process as the main line and applies safety principle and accident control theory, accidents and occupational hazards in chemical production are systematically analyzed and elaborated to ensure the stability of chemical production.
    Due to the lack of experience of the editor, it is inevitable that there are mistakes anddefects in the book. Readers are eager to criticize and correct them.

化工生产是经济社会发展的重要支柱。一方面，化工生产有力地促进了国民经济的发展，改善和提高了人们的生活水平；另一方面，在化工（特别是危险化学品）生产过程中存在着许多不安全因素和职业危害，如易燃、易爆、易中毒、高温、高压、有腐蚀等，因此比其他工业生产有着更大的潜在危险性。在化工产过程中，风险是客观存在的，虽然看不见、摸不着，但它却与生产活动密不可分，如影随形。
       本书从加强化工从业人员安全生产技术培调工作出发，按照“安全第一、预防为主、综合治理”的工作方针，运用化学工业的基本原理和方法，结合化工安全生产的特点，系统分析了化工生产过程中各种危险因素，预测发生事故或造成职业危害的可能性及其严重程度，提出了科学、合理、可行的安全生产预防措施及控制方法，以化工生产过程为主线，应用安全原理与事故控制理论，对化工生产中的事故和职业危害进行了系统地分析与阐述，确保化工生产稳定。
      由于编者经验不足，书中的错误和不妥之处在所难免，恳切读者批评指正。

With the continuous improvement of China’s engineering construction system, the increasing construction market and the increasingly fierce market competition, it is more and more important to realize the modern management of engineering project construction. The scientific engineering project management theory, methods and means, the socialization and specialization of management personnel, the core of knowledge management, and the informatization of management are increasingly prominent.
    This book starts from highway project construction management and highway construction maintenance. According to modern project management theory, using information and network technology, and combining with the actual situation of other expressway projects, the book constantly innovates in project management practice, and integrates the management value concept, method, measures and knowledge utilization information means of project managers. The project dynamic management system is constructed and applied to expressway construction project management. Highway as a traffic product, its construction directly reflects whether the traffic in a region is developed. With the continuous development and improvement of modern transportation, people’s living standard has been improved day by day, and the highway is more and more important for people’s daily life. Therefore, it is of great significance to improve the management level of expressway and ensure the safety and smoothness of highway. As the infrastructure of a country, highway belongs to the scope of public goods in essence, and has the nature of social public welfare. Therefore, in order to better improve the management level of expressway and ensure the safety and smoothness of highway, it is necessary to strengthen the construction management of expressway and strengthen the innovation of maintenance measures. Due to the author’s lack of experience, there may be mistakes and omissions in the article. Readers can give criticism and correction.

“Harmonious city” is not only a goal, but also a tool to analyze the current situation of urban development and propose solutions. We should not only see the four key areas supporting the “harmonious city”: the harmonious space and region, the harmonious society and economy, the harmonious environment and the planning and control oriented to the harmonious city, but also see the intangible assets that contribute to the urban harmony discussed in the report, such as cultural heritage, sense of place and memory, complex social and symbolic relationship, etc. These intangible assets, which represent the soul of the city, are as important as the tangible assets for the harmonious development of the city. The establishment of “harmonious city” is fundamentally based on the harmony between man and nature, man and man, spirit and material. The harmonious development of urban economy, the harmonious life in the age of science and technology, the harmonious operation of community cells and the harmonious interaction between the city and the countryside. The foundation of this foundation lies in the harmony of urban and rural multi cultures.
    Due to the different development stages of cities, the research on urban planning evaluation in western developed countries started earlier, and gained rich experience and research results in theory, method and practice. Since the 1950s, with the promotion of the application of systematic method in the field of urban planning and the further improvement of economic and policy scientific methods, the research on urban planning evaluation has been widely carried out. At the beginning of the 21st century, the urban planning evaluation research in western developed countries has gone through a total of 60 years of development, and has initially formed a relatively complete evaluation theoretical system. The evaluation content extends from single scheme evaluation to comprehensive evaluation of planning value standard, public policy expression, planning implementation process and planning implementation effect; the evaluation method extends from qualitative evaluation to the combination of qualitative and quantitative evaluation, and constructs index system to evaluate each content; the evaluation practitioners are also from government departments, third-party professionals to the public; and has established a relatively complete evaluation information system and evaluation implementation mechanism.

“和谐城市”既是一个目标，又是一个分析城市发展现状问题和提出解决途径的工具。我们不仅仅要看到支撑“和谐城市”的四个关键领域：空间区域和谐社会经济和谐、环境生态和谐和面向和谐城市的规划管制，更应该看到报告中讨论的对城市和谐作出贡献的各种无形资产，例如文化的传承、场所感和记忆，复杂的社会与象征性关系等赋予城市意义的要素，这些代表了城市灵魂的无形资产与有形资产对于城市的和谐发展一样至关重要。建立“和谐城市”，是从根本上立足于人与自然人与人、精神与物质和谐，在形式上体现为多元文化的和谐共存。城市经济的和谐发展、科技时代的和谐生活、社区细胞的和谐运作以及城市和乡村的和谐互动，而此基础之上又在于城市多元文化和乡村多样文化的和谐。

 由于城市自身所处的发展阶段不同，西方发达国家对城市规划评估的研究开始较早，取得了较丰富的理论、方法以及实践方面的经验和研究成果。从 20 世纪 50年代开始，随着系统方法在城市规划领域运用的推进和经济学、政策科学方法的进一步完善，对城市规划的评价研究得到了广泛的开展。到 21 世纪初期，西方发达国家的城市规划评估研究总共经过了 60 年的发展历程， 初步形成了较为完善的评估理论体系。评估内容从单一的方案评估扩展到对规划价值标准、公共政策表达、规划实施过程、规划实施效果等全面的评估；评估方法从定性评价扩展到定性与定量相结合、构建指标体系评价各个内容；评估从业人员也从政府部门、第三方专业人士到市民大众；并且建立了较为完善的评估信息系统和评估实施机制。
