This book presents novel design principles and technologies for dynamic isolation based on experimental studies. These approaches have now become the local standard in Beijing and are currently being promoted for use nationwide. Further, the book provides details of measures and guidelines for the design process. Departing from the traditional understanding that isolation wards should be designed with high negative pressure, airtight doors and fresh air, it establishes the basis for designing biological clean rooms, including isolation wards, using a simple and convenient scientific approach. This book is intended for designers, engineers, researchers, hospital management staff and graduate students in heating ventilation air conditioning (HVAC), air cleaning technologies and related areas.
This book discusses the development, types and application principles of portable air purifiers in China. It analyzes the theoretical characteristics of air purifiers under various operational conditions, and points out that the term “Clean Air Delivery Rate” cannot be used to precisely reflect the problems that occur under various operational conditions. By comparing theoretical and measured data, it highlights the mainfeatures of air purifiers and key points in the design process for different applications. Calculation methods for the indoor particle concentration and the self-purification time are also provided. The book describes the conditions for window opening in smog and for selecting air purifiers, and proposes a newmethod for improvingtheir measurement. In closing, it includes a new assessment index.
Creation of the Gods, a Chinese literary classic, ranks among great works as The Three Kingdoms, Water Margin and Journey to the West. It relates the struggles between forces of King Zhou, the despotic last ruler of the Shang dynasty, and Jiang Ziya, the legendary commander and strategist who helped found the Zhou dynasty in the 11th century BC. The ensuing battles were a spectacular drama featuring enlightened priests, immortals, spirits, demons, kings and generals. Astride exotic animals or soaring on clouds, they duelled with a formidable array of magic weapons that will captivate the reader from beginning to end. Cartoonist Chan Kok Sing, well loved for his brand of comic animation and humour, has depicted the Chinese masterpiece with a new energy that both educates and entertains. There is no better way to rediscover the saga of the infamous King Zhou and his vixen-concubine, and how they got their just deserts from the army of the virtuous Wen, founder of the Zhou dynasty.
A masterpiece." —The Washington Post "It was impossible. All of China was a prison in those days." Mao Zedong’s labor reform camps, known as the laogai, were notoriously brutal. Modeled on the Soviet Gulag, they subjected their inmates to backbreaking labor, malnutrition, and vindictive wardens. They were thought to be impossible to escape—but one man did. Xu Hongci was a bright young student at the Shanghai No. 1 Medical College, spending his days studying to be a professor and going to the movies with his girlfriend. He was also an idealistic and loyal member of the Communist Party and was generally liked and well respected. But when Mao delivered his famous February 1957 speech inviting “a hundred schools of thought [to] contend,” an earnest Xu Hongci responded by posting a criticism of the party—a near-fatal misstep. He soon found himself a victim of the Anti-Rightist Campaign, condemned to spend the next fourteen years in the laogai. Xu Hongci became one of the roughly 550,000 Chinese unjustly imprisoned after the spring of 1957, and despite the horrific conditions and terrible odds, he was determined to escape. He failed three times before finally succeeding, in 1972, in what was an amazing and arduous triumph. Originally published in Hong Kong, Xu Hongci’s remarkable memoir recounts his life from childhood through his final prison break. After discovering his story in a Hong Kong library, the journalist Erling Hoh tracked down the original manuscript and compiled this condensed translation, which includes background on this turbulent period, an epilogue that follows Xu Hongci up to his death, and Xu Hongci’s own drawings and maps. Both a historical narrative and an exhilarating prison-break thriller, No Wall Too High tells the unique story of a man who insisted on freedom—even under the most treacherous circumstances.
The book provides general knowledge of automatic control engineering and its applications. Providing an overview of control theory and systems, the chapters introduce transfer functions, modeling of control systems, automatic control systems, block diagrams, and signal flow graphs. While control system analysis and design are accompanied by root-locus methods and frequency response analyses, distributed control systems, nonlinarity in control systems including Z-transformation are also presented. With straightforward demonstrations, examples, and multiple-choice questions, this book can be used as a reference textbook for electrical and electronics engineering, computer control engineering, automation engineering, mechatronics engineering, mechanics, robotics, AI control systems, hydraulics, process engineering, safety control engineering, aeronautical and aerospace engineering, auto-pilot system, decision-making system, and stock exchange, and will be suitable for majors, non-majors, and experts in the field of science and technology.
This book explores poems, novels, legends, operas and other genres of writing from the Ming Dynasty. It is composed of two parts: the literary history; and comprehensive reference materials based on the compilation of several chronologies. By studying individual literary works, the book analyzes the basic laws of the development of literature during the Ming Dynasty, and explores the influences of people, time, and place on literature from a sociological perspective. In turn, it conducts a contrastive analysis of Chinese and Western literature, based on similar works from the same literary genre and their creative methods. The book also investigates the relationship between literary theory and literary creation practices, including those used at various poetry schools. In closing, it studies the unique aesthetic traits of related works. Sharing valuable insights and perspectives, the book can serve as a role model for future literary history studies. It offers a unique resource for literary researchers, reference guide for students and educators, and lively read for members of the general public.
Challenges the accepted wisdom about women and gender roles in medieval China. In Crossing the Gate, Man Xu examines the lives of women in the Chinese province of Fujian during the Song dynasty. Tracking womens life experience across class lines, outside as well as inside the domestic realm, Xu challenges the accepted wisdom about women and gender roles in medieval China. She contextualizes women in a much broader physical space and social network, investigating the gaps between ideals and reality and examining womens own agency in gender construction. She argues that womens autonomy and mobility, conventionally attributed to Ming-Qing women of late imperial China, can be traced to the Song era. This thorough study of Song womens life experience connects women to the great political, economic, and social transitions of the time, and sheds light on the so-called Song-Yuan-Ming transition from the perspective of gender studies. By putting women at the center of analysis and by focusing on the local and the quotidian, Crossing the Gate offers a new and nuanced picture of the Song Confucian revival.
In the 1960s and 1970s, around 17 million Chinese youths were mobilized or forced by the state to migrate to rural villages and China's frontiers. Bin Xu tells the story of how this 'sent-down' generation have come to terms with their difficult past. Exploring representations of memory including personal life stories, literature, museum exhibits, and acts of commemoration, he argues that these representations are defined by a struggle to reconcile worthiness with the political upheavals of the Mao years. These memories, however, are used by the state to construct an official narrative that weaves this generation's experiences into an upbeat story of the 'China dream'. This marginalizes those still suffering and obscures voices of self-reflection on their moral-political responsibility for their actions. Xu provides careful analysis of this generation of 'Chairman Mao's children', caught between the political and the personal, past and present, nostalgia and regret, and pride and trauma.
