The effect of zeolites ion-exchanged by transition metals on thermal catalytic cracking reaction is studied. The product distributions of the cracking reactions catalyzed by theβor ZSM-5 zeolites exchanged with transition metals are different from that catalyzed by corresponding Hzeolites, which means the mechanism of cracking reactions has varied. Group Ⅷ metals Fe, Co, Ni and Cu, Zn are shown to be of strong catalytic activity of oxidative dehydrogenation, while Ti and Cr are not of oxidative activity. Catalyzed by zeolites or catalyst containing Ag, conversion of thermal catalytic cracking reactions and the yield of ethylene increase while the yield of propylene does not decrease. Silver can not only promote the formation of carbonium ion, but also convert carbonium ion into free-radical via redox reaction. The weak adsorption of olefins on silver reduces the occurrence of hydrogen transfer and dehydrogenation. As a result, the yield of light olefins is favored by silver in the catalyst.

采用过渡金属交换的分子筛作为催化剂，进行催化热裂解制取乙烯的反应，研究发现，在β沸石分子筛和ZSM-5分子筛中引入过渡金属后，催化热裂解反应的产物分布与相应的氢型分子筛相比有了较大的变化，说明过渡金属的加入对于催化热裂解反应的机理具有影响，Ⅷ族金属如Fe、Co、Ni和第Ⅰ、Ⅱ副族Cu、Zn表现出较强的氧化脱氢活性，产物中氢气、焦炭的产率很高，Ti、Cr则未表现出氧化作用：分子筛及催化剂中引入银后，催化热裂解反应的转化率和乙烯的产率有了提高，丙烯产率没有很大的变化，说明银在催化热裂解反应中能够促进正碳离子的生成，又有可能通过氧化-还原作用部分改变反应机理，促进了自由基的生成，并且由于银对烯烃的吸附很弱，其氢转移反应和脱氢、加氢活性比较低，有利于烯烃产率的提高。

Three new groups of near-Sun comets have since been identified, two of them by German amateurs. In January 2002, Maik Meyer - who manages the Catalogue of Comet Discoveries Web site ( http://www.comethunter.de/) and has found 37 SOHO comets - noted that a newly discovered non-Kreutz SOHO comet and one found four years earlier had similar orbits.

自从SOHO上天后，又有3个新的族被发现，其中两个是由德国的业余爱好者发现的。2002年1月，发现了37颗彗星的德国爱好者Maik Meyer （他的彗星发现网站是 http：//www.comethunter.de/注意到，一颗心发现的非Kreutz族彗星和4年前发现的一颗有着相似的轨道。

Then quality upgrading scheme was explored in order to solve the high content of sulphur and nitrogen in pyrolytic oil, low flash point as well. Yields of pyrolysis of scrap tires in a pilot-scale rotary kiln under 550℃were firstly summarized. Then elemental composition and physiochemical properties were analyzed on both pyrolytic crude oil and its fractions. Based on these researches, the feasibility that pyrolytic oil is used as fuel was discussed. From FT-IR spectra the functional group compounds were generally acquainted, and by column chromatography analysis chemical compositions were clearly known. Then through GC analysis the absolute content of BTX in pyrolytic crude oil was defined.

本文首先考察了中试回转窑550℃下的废轮胎热解产率及热解原油的元素组成和理化特性，对其作为燃料使用的可行性进行了分析；通过实沸点蒸馏研究了轻质、中质馏分热解油的基本特性：红外分析得出了有代表性馏分热解油的大致官能团组成形式，对热解油的强芳香性和部分不饱和性有了整体了解；化学族组成分析进一步了解了热解油内在化学族组成和含量，对热解油的内在性质有了更为深入理解；气相色谱分析对热解油中富含的苯、甲苯和二甲苯进行绝对定量，为热解油提取BTX化工原料的经济性提供了参考。

Though historically there is a discernible break between Jewish law of the sovereign state of ancient Israel and of the Diaspora （the dispersion of Jewish people after the conquest of Israel）, the spirit of the legal matter in later parts of the Old Testament is very close to that of the Talmud, one of the primary codifications of Jewish law in the Diaspora.

尽管古代以色列君主国的法律与后来离散的犹太族（以色列征服后分散的犹太人）法律有所区别，但是以前遗嘱后面部分的精神实质与犹太法典是非常相近的，犹太法典是离散的犹太族中一种主要的法典编纂。

Appointed governor of the new Indiana Territory in 1800, Harrison had the job of defending and extending white settlements, and he did so by going back into battle. In 1811, as the threat organized by the Shawnee Indian chieftain Tecumseh grew stronger, Harrison successfully led about a thousand men against a Shawnee uprising on the Tippecanoe River on Nov. 7. He earned the nickname "Old Tip," but more importantly the rank of brigadier general and was given command of U.S. forces in the Northwest.

於1800年派任为新疆域印第安那州州长，哈里森的任务在於保护并扩张白种人的定居之地，1811年因为受到萧尼族印地安人酋长Tecumseh的威胁日盛，哈里森在11月7日成功地带领千名人民、於蒂珀卡努河对抗萧尼族，他因此得到「老将」的昵称，更重要的是、他获得准将的职阶，负责号令美国在西北方的军队。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
