The latest report of the World Health Organization shows that mental illness is showing a significant upward trend worldwide. About 154 million people worldwide suffer from depression, and 25 million suffer from schizophrenia. In addition, 50 million people suffer from epilepsy and 24 million suffer from dementia. At present, mental health has become a prominent social problem. Mental illness is a very common phenomenon in all countries in the world. People who are not mentally healthy are easily isolated by society, their quality of life decreases, and the suicide rate is higher. It is reported that the main reasons leading to the high incidence of mental illness include marital problems, rising unemployment, and cultural conflicts. In line with this, in recent years, the mental health movement has quietly risen around the world. Taking the United States as an example, since the rise of the mental health movement, today, 10 to 15 million people have participated in the movement, and various mental health activity groups have reached 750,000. In 1948, when the World Health Organization (WHO) was founded, in its charter, health was defined as: “Health is a state of well-being physical, psychological, and social adaptation, not just the absence of disease and weakness. status.”
   At present, the concept of a globalized healthy community is quite popular. The World Health Organization (WHO) not only needs health care services for health, but also requires clean air, water, safe communities, green grasslands, good housing and other material and social environments. In order to explore the practical model of creating a healthy community in China, to ensure and promote “health for all”, “mental hygiene” is more needed, and to explore the reality of China to create a healthy community to ensure and promote “health for all”, what is more needed is “ Mental health”. To do a good job in the prevention, medical treatment and rehabilitation of patients with mental health diseases, and to improve medical consultation and publicity for mental health, it is necessary to understand the preventive measures for everyone’s health from different ages and different groups to cultivate public health.

世界卫生组织最新报告显示，精神疾病在世界范围内正呈显著上升趋势。全世界共有约 1.54 亿人饱受抑郁症的困扰， 2500 万人患有精神分裂症。另外，有 5000万人患有癫痫， 2400 万人患有痴呆症。目前，精神卫生已经成为一个突出的社会问题。精神疾病在世界各国都是十分普遍的现象，精神上不够健康的人群容易被社会孤立，生活质量下降，自杀率更高。据悉，导致精神疾病高发的原因主要包括婚姻问题、失业率上升、文化冲突等。与此相适应的是，近些年来，心理健康运动已在全球悄然兴起。 以美国为例， 自心理健康运动的兴起到蓬勃发展的今天， 已经有 1000万至 1500 万人参加了这场运动，各种心理健康活动团体达到 75 万个。 1948 年，世界卫生组织（WHO）成立时在宪章中把健康定义为： “健康乃是一种生理、心理和社会适应都臻完满（well-being）的状态，而不仅仅是没有疾病和虚弱的状态。 ”
      目前全球化的健康社区概念颇为盛行，世界卫生组织(WHO)对健康不仅需要卫生保健服务，还需要有清洁的空气、水、安全的社区、绿色的草地、良好的住房等物质和社会环境。 为探索适合中国实际的创建健康社区模式， 确保和促进“人人健康”更需要的是“精神卫生”，探索中国实际的创建健康社区，确保和促进“人人健康”，更需要的是“精神卫生”。做好精神卫生疾病者的预防、医疗和康复，提高精神健康医学咨询、宣传，必须从不同年龄、不同群体了解人人健康的预防措施，培养公众健康素养。

People have human bones, animals have animal bones, and structure is the skeleton of architecture. Many strange life bodies in the world rely on bones to support the weight of the body. The more advanced creatures are, the more complex the bones are, and the same is true of buildings. The shape and space of buildings depend on their skeleton: structure bearing. As different lives have different bones, different buildings also have different structures, different architectural structures determine the use of the building performance. Architectural design is of great significance to the construction. Generally, the reliability, safety and bearing capacity of buildings can be judged by the design scheme.
   In addition, the structural elements in architectural design affect the overall shape. Within the scope of structural mechanics, when adjusting the number, proportion, arrangement and cross-section form of beams, columns and walls, the seemingly boring structure shows extremely rich expressive force. For example, columns can be arranged as colonnades. Colonnades with different lengths, heights and spacing have different personalities; columns and walls can be regarded as lines and surfaces in composition to form a certain texture. This book is based on the author’s many years of working experience, combined with theory and practice, put the experience and experience in work practice into writing, and write it on paper, hoping to provide a more practical summary for peers.

人有人的骨骼，动物有动物的骨骼，结构是建筑的骨骼。大千世界千奇百怪的生命体，很多都依赖骨骼承托着身体的重量。越是高级的生物，骨骼就越复杂，而建筑也同样，建筑的造型、空间等内容，都依赖它的骨骼—结构承重着。如同不同的生命有着不同的骨骼一样，不同的建筑也有着不同的结构，不同建筑构造决定着建筑的使用性能。建筑设计对建筑构造具有非常重要的先行意义，一般通过设计方案可判断建筑可靠性、安全性以及承载能力。
      此外，建筑设计中的结构要素影响着整体的造型。在结构力学允许的范围内，调整梁、柱、墙的数量、比例、排列方式和截面形式等因素时，看似枯燥的结构就展现出无比丰富的表现力。例如可以把柱子陈列成柱廊，不同长度、不同高度、不同间距的柱廊有着不同的性格；也可以将柱子和墙当成构成中的线和面，组成一定的肌理。而本书基于笔者多年从业经验，结合理论、联系实践，将工作实践中的心得和体会付诸笔端，写在纸上，希望能够为同行朋友提供一种更具实践性的汇总。

The chemical industry occupies an important position in the national economy of all countries in the world. The chemical industry can not do without chemical safety production. The safe production and stable operation of chemical industry are the guarantee of our national economy. However, chemical production has the characteristics of complex and changeable production process, flammable and explosive raw materials and products, toxic and harmful and corrosive, large-scale production equipment, continuous process and automation, so there are potential risk factors in the production process, which is prone to destructive accidents. Safety production is the most important problem in chemical industry. The task of chemical safety production is to eliminate the unsafe factors in the production process and create a good safe and comfortable working environment and work order. We should turn danger into safety, harm into harmlessness, and heavy labor into light labor, so as to prevent accidents and occupational diseases and ensure the safety and health of employees.
   At present, the global environmental problem is one of the biggest threats to human beings. It is an important content of environmental protection work to strengthen the education of environmental science knowledge, popularize the knowledge of environmental protection and enhance the awareness of environmental protection of the whole people. Chemical production is characterized by the diversification of products, raw material lines and production methods. Many pollution incidents are caused by chemical production and chemical substances. Therefore, chemical industry has become one of the main sectors of environmental pollution. Environmental protection and ecological balance are the necessary prerequisite for human survival and development. Therefore, it is a long-term and very important task for chemical industry to persist in popularizing chemical safety technology, strengthening safety education and training for employees, improving people’s safety technical quality and ensuring safe production of chemical industry.
