This book summarizes the research results of carbide control in special steel from the authors. It includes the evolution and control of carbide in special steel in the process of electroslag remelting, rolling, and heat treatment, as well as the effect of alloying treatment (rare earth, magnesium, nitrogen, titanium) as heterogeneous nucleating agent on the carbides in special steel. It helps the readers to understand the formation mechanism and control technology of carbide in special steel deeply for improving the quality of special steel further. The book is useful as a reference for researchers, practitioners, teachers, and engineering management team in the fields of metallurgy and materials.

Compared to the conventional Rankine cycle using water, the ORC can create efficient expansion at low power, avoid superheater and offer higher thermal efficiency in low temperature application. Small-scale ORCs from several kWe to a few hundred kWe offer great potential for meeting the residential demand on heat and power, and are of growing interest in scientific and technical fields. However, one critical problem is the decreased device efficiency and cost-effectiveness that arises when the ORC is scaled down. In this thesis, the ORC is combined with low concentration-ratio solar collectors. The background, research trend, merits and importance of the solar ORC are described. To reduce the thermodynamic irreversibility and the cost of the system, three innovative solutions are proposed: solar ORC without heat transfer fluid (HTF), which employs two-stage collectors and heat storage units; hybrid solar power generation based on ORC and amorphous silicon cells; osmosis-driven solar ORC. Heat collection, storage and power conversion are optimized. The design, construction and test of a prototype are conducted, demonstrating the feasibility of the ORC for small-scale cogeneration. Special attention is paid to the variable operation and parameter design with respect to the condensation temperature.

A fascinating look at Chinese perceptions of the United States and the cultural and political background that informs them. 2011 CHOICE Outstanding Academic Title Winner of the 2011 Best Book Award presented by the Chinese American Librarians Association What do the Chinese think of America? Why did Jiang Zemin praise the film Titanic? Why did Mao call FDR's envoy Patrick Hurley "a clown?" Why did the book China Can Say No (meaning "no" to the United States) become a bestseller only a few years after a replica of the Statue of Liberty was erected during protests in Tianamen Square? Jing Li's fascinating book explores Chinese perceptions of the United States during the twentieth century. As Li notes, these two very different countries both played significant roles in world affairs and there were important interactions between them. Chinese view of the United States were thus influenced by various and changing considerations, resulting in interpretations and opinions that were complex and sometimes contradictory. Li uncovers the historical, political, and cultural forces that have influenced these alternately positive and negative opinions. Revealing in its insight into the twentieth century, China's America is also instructive for all who care about the understandings between these two powerful countries as we move into the twenty-first century.

Die vorliegende Studie ist eine rechtslinguistische Untersuchung zur Explizierung des textgestützten und diskursbasierten Rechtsstreits zwischen verschiedenen Rechtsarbeitern (Richter, Staatsanwalt, Rechtsanwalt) im Rechtsfindungsverfahren. Als Untersuchungskorpus gelten die authentischen Textmaterialien (Anklageschriften, Berufungs- bzw. Revisionsschriften, Urteile und Schriftsätze usw.) von sechs zusammenhängenden Rechtsfällen aus der deutschen Rechtspraxis. Die Analyse setzt sich zum Ziel, einerseits zugunsten des interdisziplinären Erkenntnisinteresses einen exemplarischen Beitrag zu der in Anbetracht ihrer Relevanz noch relativ wenig erforschten textlinguistischen Beschäftigung mit Rechtstexten zu leisten und andererseits den fachspezifischen Kommunikationsvorgang in stärkerem Maße anhand linguistischer Instrumentarien verständlich zu machen. Die entwickelten Beschreibungsansätze richten sich auf die differenzierten Sprachhandlungsmuster und die dabei verwendeten spezifischen Handlungsstrategien und Perspektivierungsanstrengungen. Dadurch wird sowohl juristischen Fachleuten als auch Laien ein transparentes Analysemodell der Rechtskommunikation unterbreitet.
