采用单体自增溶原位固相接枝法合成了聚乙烯与三单体固相接枝物(PETM)。采用Coats-Redfma法和Doyle-Ozawa法研究了接枝物的热分解动力学。研究表明,受接枝支链的影响,PETM的热分解反应级数介于0~1之间。PETM的热分解活化能比PE高... 采用单体自增溶原位固相接枝法合成了聚乙烯与三单体固相接枝物(PETM)。采用Coats-Redfma法和Doyle-Ozawa法研究了接枝物的热分解动力学。研究表明,受接枝支链的影响,PETM的热分解反应级数介于0~1之间。PETM的热分解活化能比PE高,说明PETM的热稳定性优于PE,随着St在支链中的比例增加。PETM的热稳定性有逐渐增加的趋势,这是由于St能稳定自由基,从而降低PE的热分解速率。 展开更多

Sherlock Holmes, the literary image that Arthur Conan Doyle created in The Adventure of Sherlock Holmes, has undoubtedly become an iconic figure of detective. For over a century, a number of films and TV series which based on this book are countless, Sherlock Holmes has been brought to silver screen and stage for a million times. It will be mentioned Arthur Conan and Sherlock Holmes in his book at first, and then review a list of Sherlock Holmes' adaptations in the history. Secondly, showing different personalities of this figure, taking film and TV dramas adaptation as examples to compare with the original novel,from which we can discover different perspectives of this image of Sherlock Holmes. At last, it emphasizes through the ages, literary works have always been materials for films and TV programs creation. From the everlasting image of Sherlock Holmes, we can see that literary spirits in classic masterpieces can be spread and flourished through adaptation of films and TV programs. 展开更多

In the history of detective stories, Sherlock Holmes and Miss Jane Marple remain as two of the most prominent figures. Focusing on the two detectives' images, personality traits, detective strategies as well as settings of the stories, this study examines the grounds that magnetize readers.The purpose of this research is to inquire into readers' orientations to Sherlock Holmes and Miss Jane Marple, and to investigate the causes for their views. To fulfill that purpose, a questionnaire was designed and distributed. Sherlock Holmes and Miss Jane Marple prove themselves to be successful detectives. Both of them have distinct images and personality traits as well as plausible detective strategies. The settings, combining reality with imagination, also play a dispensable role. Besides, reasons given by students who disbelieve that they are real persons fail to convince. 展开更多

Modern detective novels are believed to have their roots in Sir Arthur Conan Doyle's Sherlock Holmes, when nearly fifty years prior Edgar Allen Poe had published one of the first murder mysteries in history. Although many years had elapsed little change had been made to the major elements of these detective stories. This essay explores the similarities of"Murders in the Rue Morgue"and"Hound of the Baskervilles". 展开更多
