Personnel archives management is an important work in the management of modern institutions and enterprises. It is a direct reflection of an employee's work experience, work attitude and work ability. The quality of personnel archives management in an enterprise is directly related to the development of employees and the construction and development of the enterprise. With the progress of society and the development of science and technology, personnel archives management also presents new changes. It has the great impact on informatization. Therefore, in the new situation, personnel archives management must also be informatized. In the 21st century, informatization and digitization have become the main trend of the society. Many industries in the society have implemented information management, which has brought great convenience to their development, including personnel archives management. The information construction of personnel archives management is to use computer technology to convert paper files into electronic files and finally realize the sharing of personnel archives information resources online. Therefore, in the current development and construction of science and technology, the information construction of personnel files has become an inevitable trend. Based on information construction, personnel archives management can keep pace with the times.

This book is divided into six chapters, which respectively elaborates the basic contents of personnel archives management and information construction, analyzes the existing problems at the current stage, and proposes corresponding solutions.

人事档案管理是现代事业单位和企业经营管理中的重要工作，人事档案是一个员工工作经历、工作态度以及工作能力的直接体现，一个企业的人事档案管理工作的质量，直接关系着企业员工的发展以及企业的建设和发展，随着我国社会的进步和科技的发展，人事档案管理工作也呈现出了新的变化，其中最主要的就是信息化对其的影响。所以在新的形势下，人事档案管理工作也必须要进行信息化建设。进入21世纪，信息化和数字化成为社会的主要趋势，社会上很多行业实行了信息化管理，信息化的管理给其发展带来了极大的便利，其中就包括了人事档案管理工作。人事档案管理工作的信息化建设就是利用计算机技术，将纸质档案转为电子档案，最终实现网上人事档案的信息资源共享。所以，在现在的科技发展和建设中，人事档案的信息化建设，已经成为了必然的趋势，要进行信息化建设，人事档案管理工作才能够与时俱进，获得发展。

本书主要分六章内容，分别对人事档案管理和信息化建设进行基础内容的阐述与分析，还就现阶段存在的问题进行分析，并提出相应的解决策略。

In modern history, the progress of information technology has a great impact on education. On the one hand, traditional education is facing severe challenges; on the other hand, it also creates good opportunities for the further development of education. With the arrival of the information age, countries all over the world have paid unprecedented attention to the application of information technology in education. The rapid development of technology has made it possible to achieve the previously unattainable means or more ideal teaching methods. However, the reality is not as optimistic as people think. This is because many teachers in classroom teaching cannot effectively use this new technology means and methods to achieve efficient classroom teaching. The reasons are quite complicated, but the main reason is that information technology and classroom teaching fail to form an organic whole. Therefore, to change this situation, some necessary measures must be taken to make information technology play an important role in classroom teaching. However, to make better use of computer teaching, network security must be guaranteed.

This book gives a brief overview of the computer system, introduces modern educational technology and computer aided teaching, and expounds the security management of the network.

在近现代历史上，信息技术的每一项进步，都对教育产生巨大影响。一方面是传统教育面临着严峻的挑战，另一方面，也为教育进一步发展创造了良好的机遇。信息时代的到来，使世界各国对发展信息技术在教育中的应用，都给与了前所未有的关注，以其技术发展极快的特点，使原来可望而不可及的手段或比较理想的教学方式变得可能了。然而，现实的情况并非像人们想象的那么乐观，这是因为许多教师在课堂教学中不能有效地运用这一新技术的手段和方法来实现高效率的课堂教学，究其原因是相当复杂的，但其中最主要的原因是信息技术与课堂教学未能形成有机的整体。因此，要改变这一状况，必须采取一些必要的步骤，使信息技术在课堂教学中发挥重要作用。然而要想更好地使用计算机教学，必须保证网络的安全性。

本书先通过对计算机系统进行简要的概述，接着介绍了现代教育技术、计算机教学，并对网络的安全管理进行了阐述。

China is a big country producing fruit and vegetable, and its output ranks first in the world. The fruit and vegetable processing industry has become an important part of the scale of fruit and vegetable planting. With the development of the economy and the improvement of people's living standards, people are paying more and more attention to food nutrition and their health. Fruit and vegetable juice beverages are rich in carbohydrate, amino acid, vitamins and mineral substance and other nutrients that are easily absorbed by the body, which can meet people's daily physiological need. Similarly, with the continuous advancement of science and technology, the freezing and refrigeration technology of food is getting more and more popular. The low-cost, long-term and high-quality preservation of food can be achieved by freezing and refrigerating food, which is the most commonly used method of food storage. By inhibiting the activities of microorganisms and enzymes and reducing the activity of food substrates, food spoilage can be prevented and the freshness and nutritional value of food can be maintained. At present, most places of freezing and refrigerating food in the market are large-scale refrigerators and freezers; and most households are generally refrigerators. The efficient and high-quality connection between the market and users depends on the construction of the refrigeration chain.

Through a brief introduction, this book will discuss the postharvest physiology, harvesting and commercial processing of fruit and vegetable products, fruit and vegetable storage, canned fruit and vegetable, quick-frozen fruit and vegetable, fruit and vegetable juice-making, fruit and vegetable sugar-making, fruit and vegetable pickling, fruit wine brewing, fresh-cut fruits and vegetable processing, and comprehensive utilization of raw fruit and vegetable.

我国是水果和蔬菜生产大国，产量均居世界第一位，果蔬加工业已成为果蔬种植业规模化的重要环节。随着经济的发展和人们生活水平的提高，人们越来越重视食品营养与自身健康。果蔬汁饮料含有丰富的碳水化合物、氨基酸、维生素和矿物质等多种易被人体吸收的营养物质，能够满足人们日常的机体生理需要。同样，随着科学技术的不断进步，食品的冷冻冷藏技术越来越得到大家的喜爱，而且对食品的冷冻冷藏可实现食品的低成本、长时间、高品质的保存，是目前最普遍采用的食品贮藏方法。通过抑制微生物及酶类的活动和降低食品基质中的活性，来防止食品腐败变质，保持食品的新鲜度和营养价值。目前对市场食品冷冻冷藏的场所多为大型冷藏库、冷冻库，一般家用多为冰箱，实现市场与用户的高效、高品质的联系有赖于冷藏链的建设。

本书将通过简单的介绍，对果蔬产品采后生理、采收与商品化处理、果蔬贮藏、果蔬罐藏、果蔬速冻、果蔬制汁、果蔬糖制、果蔬腌制、果酒酿造、鲜切果蔬加工、果蔬原料的综合利用等方面加以论述。

With the improvement of people's living standards and the strengthening of self-health protection awareness, the requirements for the detection of textile products have been further improved. Therefore, we need to adapt to the development trend of the times, constantly innovate and develop new testing technologies, and strive to make the produced textiles meet the internationally accepted testing standards, so that China's textiles can truly achieve barrier-free exports and become a real textile exports power, and thus improve our comprehensive economic strength.

This book briefly introduces the status quo and development of textile materials, textile industry development and new materials application, the present situation and development of China's textile testing technology; and then systematically elaborates and studies six chapters, including the recognition and identification of textile materials, textile material performance testing, textile fiber material testing, yarn and its quality testing, textile quality testing and detection of harmful substances in ecological textiles. It is a practical and useful textile industry reference book.

随着人们生活水平的提高，自我健康保护意识的加强，进一步提高了对纺织产品检测的要求。因此，就需要我们顺应时代的发展潮流，不断地创新开发出新的检测技术，并且争取使生产出的纺织品能顺利通过国际通用的检测标准，从而使我国纺织品真正的实现无障碍的出口，成为真正的纺织品出口大国，进而提高我国的综合经济实力。

本书先就纺织材料、纺织业发展与新材料应用、我国纺织品检测技术的现状与发展进行简要介绍，后对纺织材料的认识与鉴别、纺织材料的性能检测、纺织纤维材料检测、纱线及其品质检测、纺织物的品质检测以及生态纺织品中有害物质的检测六部分内容进行系统阐述与研究，是一本切合实际、非常实用的纺织业工具书。

In recent years, China's economy has developed rapidly, and people's demand for travel has increased. This also drives the rapid development of China's transportation industry. The number of private cars is increasing, while the contradiction between urban road supply and transportation demand is increasingly acute. Many urban roads and bridges have been difficult to meet the increasing transportation demand. The phenomenon of overload fatigue operation, coupled with the overload of some vehicles, road and bridge disease problems occur from time to time. The occurrence of road and bridge diseases not only shortens its service life, brings enormous economic losses to the country and people, but also lay hidden danger for transportation safety. In recent years, accidents caused by road and bridge collapse have occurred from time to time. Therefore, the construction team must strictly follow the relevant technical standards for construction and strengthen supervision to ensure the quality and safety of the construction. At the same time, we should also strengthen the awareness of environmental protection and avoid serious pollution to the environment during the construction process.
