Pyrolysis-Gas Chromatography/Mass Spectrometry for Microstructure and Pyrolysis Pathway of Polyester-Polyether Multiblock Copolymer

The composition and sequence distribution of monomeric units in polyester polyether multiblock copolymer were studied by pyrolysis? gas chromatography (PGC) and pyrolysis gas chromatography/mass spectrometry (PGC/MS). PGC was applied to study the F t curve of the multiblock copolymer and PGC/MS was used to separate and identify the pyrolyzates. DTA experiment was used to study the decomposition temperature. The results show that the beginning point of elastomer’s decomposition was about 300?℃ and the decomposition temperature of most of the sample was 550?℃. Many pyrolyzates were produced because of the breaking of weak bonds in the sample. The possible microstructure was verified and the pyrolysis pathway of the copolymer was investigated.

Effects of co-existing microalgae and grazers on the production of hemolytic toxins in Karenia mikimotoi

Karenia mikimotoi （Miyake ＆ Kominami ex Oda） Hansen ＆ Moestrup is associated with harmful algal blooms in temperate and subtropical zones of the world. The hemolytic substances produced by K. mikimotoi are thought to cause mortality in fishes and invertebrates. We evaluated the composition of the hemolytic toxin produced by K. mikimotoi cultured in the laboratory using thin-layer chromatography. In addition, we evaluated the effect of co-occuring algae （Prorocentrum donghaiense and Alexandrium tamarense） and the cladoceran grazer Moina mongoliea on hemolytic toxin production in K. mikimotoi. The hemolytic toxins from K. mikimotoi were a mixture of 2 liposaccharides and 1 lipid. Waterborne clues from P. donghaiense and A. tamarense inhibited the growth of K. mikimotoi but increased the production of hemolytic toxins. Conversely, K. mikimotoi strongly inhibited the growth of caged P. donghaiense and A. tamarense. In addition, the ingestion of K. mikimotoi by M. mongolica induced the production of hemolytic toxins in K. mikimotoi. Taken together, our results suggest that the presence of other microalgae and grazers may be as important as environmental factors for controlling the production of hemolytic substances. K. mikimotoi secreted allelochemicals other than unstable fatty acids with hemolytic activity. The production of hemolytic toxins in dinofiagellates was not only dependent on resource availability, but also on the risk of predation. Hemolytic toxins likely play an important role as chemical deterrents secreted by K. mikimotoi.

Three Models of English Education in China＇s Universities ——-A Historical Perspective

In the present paper, a comparison is made of the three formats in the history of EECU （English education in China＇s universities）. In the first period （1904-1949）, English education was conducted separately in government-managed educational institutions and in institutions sponsored by church-related organizations; English education was well-knit with both general education and specialty education; and self-motivating learning was encouraged. In the second period （1950-1966）, almost everything was tinted with a shady color of politics： A halt was addressed drastically to EEC （English education in China） in 1952. In the gradual recovery that started four years later, the second format was sawed and hammered, showing the following features： All non-government-mamaged institutions vanished from the stage; English was taught solely as a language or a system of verbal parts, almost deprived of all cultural loading. The third period （1978 onwards） has witnessed a barrier-free and rapid development of over three decades, resulting in the unprecedented pervasion of EECU. Yet in the third tbrmat, learners＇ efforts have turned wholly test-oriented, degenerating into the saddening disintegrity of learning as a process into isolated charges to the target of a test at a time; the ignorant reduction of the learning methods to ＂Vocabulary Booklets Plus Collections of Test Papers＂. Such a comparison not only provides a multi-dimensional perspective of EECU and a better understanding of it, but also offers some important experiences and lessons for the search of an effective solution to the pervasive problem of＂Time-Consumingness and Low-Efficiency＂.

National Ethos as a Necessary Factor in Mobilizing for Warfare

When nations are threatened with violence, the choices they make in order to cope with the challenges of war reflect different alternative possible reactions. They may choose to fight their battles fiercely or they may prefer to surrender and, sometimes, the options lay in-between. The question, therefore, is what makes nations fight and, more importantly, what causes them eventually to win or lose a war. In search of an answer to this riddle, this study examines secondary sources about three historical case studies taken from the first half of the twentieth century that deal with the Republic of Finland, the Kingdom of Norway, and the Soviet Union. It concentrates on the part played by national ethos regarding the manner in which each of them handled their wars in moments of crisis and reveals how national ethos is intertwined with another phenomenon of social psychology that turns it into a crucial factor in the management of international campaigns： enthusiasm for war. A wide historical perspective, however, shows that even though the right kind of national ethos is essential for winning a war, it is far from being enough. Hence national ethos proves, at the end of the day, to be a necessary condition for military victory, but certainly not a sufficient one.

Marx＇s Concept of Alienation： With a Brief Assessment

Since the collapse of Euro-Communism in 1989, the ideas of Marx have largely been discarded as little more than historical relics. There is a good reason for the neglect. The governments that Marxism spawns are among the most brutal in history. Equally condemnable for a philosopher who bases his theory on a science of historical development, most of Marx＇s key predictions turn out to be incorrect. What then is left of Marx＇s principles？ This paper argues that Marx is best understood as a critic of the injustice of industrial societies. Marx＇s essential critical concept is alienation. The paper presents the first complete analysis of Marx＇s treatment of alienation and offers a brief assessment of how this concept applies to our time.

Novel Coronaviruses and Astroviruses in Bats

Zoonotic transmissions of emerging pathogens from wildlife to human have shaped the history of mankind. These events have also highlighted our poor understanding of microorganisms circulated in wild animals. Coronaviruses and astroviruses,which can be found from a wide range of mammals,were recently detected in bats. Strikingly,these bat viruses are genetically highly diverse and these interesting findings might help to better understand the evolution and ecology of these viruses. The discoveries of these novel bats viruses not only suggested that bats are important hosts for these virus families,but also reiterated the role of bats as a reservoir of viruses that might pose a zoonotic threat to human health.

Discussion on the Coexistence and Fusion between Music and Literature

In the development process of human history, music and literature have their own unique characteristics, and also are closely related to each other. Both own a very long history and maintain an interdependent relationship with each other. The dances accompanied by music in China＇ s primitive tribes and the lyric poetry in the ancient Greek times can be said to be the coexistence form of music and literature. Although music and literature have undergone a whole development process from a unified development to an independent development, there are links always maintained between the two art forms. In this paper, the coexistence and fusion between music and literature are specifically introduced from different aspects.

The New Normal from the Perspective of Macro History and Grand Logic of China's Economic Development

This paper attempts to explain the "new normal" of China's economic development put forward by XI Jinping, the General Secretary of the Central Committee of the Communist Party of China, from three perspectives. First, as the new normal is a natural phase of long-term development in the country's renaissance, recognition of it helps policy-making to hold a historical perspective and maintain a patience in the face of growth slowdown. Second, the new normal as the logic of China's economic development underlines the necessity and urgency of transforming growth patterns and growth drivers. Third, different from the "new mediocre" of the world economy, the new normal reveals great potentials of sustainable growth of the Chinese economy that must be tapped through structural reforms.

当代中国美术作品中的手艺人形象

在20世纪50年代至今的新中国美术作品中,不乏有工人、农民、军人、知识分子等肖像,他们的形象反映了新中国不同时期在政策、社会、文化等方面的变化,构成了典型的历史图像志。手艺人这一主题在绘画作品中虽属少见题材,但由于其在“艺术为政治服务”的背景中并非属于“工农兵”主题;在“知识决定命运”的改革开放中的又处于边缘“形象”。

唐陵石雕鸵鸟浅说

唐朝从高祖李渊到哀帝李祝,共历21位皇帝,除昭宗李晔葬河南偃师和哀帝李祝葬山东菏泽外,其余19位皇帝死后都葬在关中,因女皇武则天和高宗李治合葬,共有18座陵墓,俗称'关中十八陵'。唐代帝陵不仅以规模宏大著称,而且以石刻众多闻名。这些石刻高大雄伟,气势磅礴,造形逼真,栩栩如生。有人称唐十八陵是一所绵延三百里的'露天石刻艺术馆',这个比喻恰如其分。

唐高宗与乾封泉宝钱

唐朝自高祖李渊(566635)武德元年(618)建国,至哀帝李祝(892908)天祐四年(907)灭亡,共历290年。唐王朝是中国历史上最强盛的封建王朝,政局稳定,经济发展较快,工商业比较发达。扬州是当时最繁华的城市之一,史载,'扬州侨寄衣冠及工商等多侵衢造宅,行旅拥弊。'[1]由此可见当时工商业的急剧发展。丝织、陶瓷、盐铁、酿酒、制糖、造纸、造船等多种行业空前繁荣,有些产品不但供应国内市场,且流向国外。当时波斯。

与时俱进的徽州人

“浮梁歙州,万国来求”。有文字记载的徽州茶始于唐,历经宋元明清和民国,至共和国时期,共历6个朝代,时近2000年。事业为人所创造,徽州茶业道路坎坷曲折,历史波澜壮阔,成就辉煌灿烂,其中打造者徽州茶商功不可没,可歌可泣。关山苍苍,岁月泱泱。回望徽州茶业的跌宕历程,撇开唐宋饼茶的贵族化时期不说,明以后散茶的平民化时期,当为内销动力,缘此形成鼎盛.
