Because of sharing characteristics with both Galliform groups, Tragopans are classified as partridges by some authors and pheasants by some others. In this study we set out to sequence the cytochrome b-gene of 19 species pheasants. and took the sequence for those 22 species from GenBank. We amplified 828 base pairs using the PCR technique. Primers designed by ourselves were based upon Galliform sequence data. Neighbor-joining method and Minimum evolution method were used to analyse cytochrome b sequences with Anhima cornuta and Kachuga dhongoka as outgroups.
通过PCR扩增鸡形目Galliformes黄腹角雉Tragopan caboti等10个属19个个体的线粒体DNA细胞色素b的部分基因,获取片段长度为828bP,以及从GenBank获取22种样本的相应序列,以角叫鸭Anhima cornuta和海龟Kachuga dhongoka为外群,分别用邻接法(Neighbor-joining, NJ)和最小进化法(Minimum-evolution, ME),对鸡形目和将雉科的15个属分为5个属及雉族和鹑族构建分子系统树,NJ和ME系统树中,都是角雉与雉类相聚。

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。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
