New technologies of aluminium extraction from wide known kaolin rocks , high - alumina schists , anorthosites and some other non - bauxite raw materials have been elaborated in the amur scientific centre ( asc ) feb ras 在阿穆尔河科技研发中心，精心开发出了铝提取新技术，可以从广为人知的高岭土岩石、高氧化铝片岩、粒状火成岩和其它非氧化铝矿原材料中提取出铝。
These results showed that cyt b gene is very suitable for identifying subspecies of tiger . we proposed specific haplotypes on cyt b gene for specifically identifying amur tiger , bengal tiger , indo - china tiger and sumatran tiger 这表明mtdnacytb基因非常适合虎亚种识别；本文提出了cytb基因上识别东北虎、孟加拉虎、印支虎、苏门答腊虎4个亚种的特异性单倍型。
The result showed that 79 polymorphic sites forming 9 haplotypes were found within the 381bp region in d - loop ; two types of sequences were discovered in d - loop region of amur tiger , short sequence that is highly homologous to other species , and long sequence that contains a 22bp insertion )个单倍型； d - loop区中存在着两种序列：一是与其他物种同源性很高的“正常序列” ，称为“短序列” ；二是带有22bp的插入片断的“非正常序列” ，称为“长序列” 。
Gland , switzerland - heavy snowfalls in the primorskii region , in far east russia , are likely to dramatically reduce the numbers of ungulates such as deers - and hence threaten their predators , the far eastern leopard and the amur tiger , wwf , the conservation organization , said here today 瑞士格兰消息世界自然基金会表示，在俄罗斯远东普里莫尔斯基地区的大风雪，可能导至如鹿等有蹄动物的数目大幅下降，而以有蹄动物为食粮的远东豹和东北虎亦因而受到威胁。
" for a long time wwf has been offering to develop an ungulates recovery programme as the basis for long - term conservation of the amur tiger and far eastern leopard , " stresses dr . yuri darman , director of wwf s operations in far eastern russia . " unfortunately this is still not in place . for the time being , we are taking emergency measures in co - operation with the wildlife and game service to save the ungulates . 世界自然基金会俄罗斯远东的项目总裁yuri darman博士强调：为了长久保育东北虎和远东豹，我们一直建议采取有蹄动物拯救计划，可惜这个计划未能实施，此时此刻，我们正联合野生物及猎物服务采取紧急措施，拯救有蹄动物。
One small captive population of amur tigers ( panthera tigris altica ) , which had 14 - year captive history since its foundation in 1986 , was selected for such population genetic researches in this paper , which contained three experimental parts as : ( 1 ) dna extraction from shed hairs . three methods , which were chelex , ionic detergent and non - ionic detergent , were respectively used to digest the shed hairs of one amur tiger 本文利用chelex 、离子型和无离子型分解液三种方法对在东北虎( pantheratigrtsaltica )换毛期采集的自然脱落毛发进行了dna提取，并对部分毛发分解原液进行蛋白质沉淀，对于毛发分解残留物也进行了核细胞分解与蛋白质沉淀再处理，对上述提取产物进行rapd扩增。
A sequence of 381bp in d - loop region of 13 amur tiger mtdna were cloned and sequenced . 2 sequences of amur tiger d - loop region and 32 sequences of cyt b gene of 4 tiger subspecies in genbank were also combined to our data in the analysis of characteristics of the two regions for evaluating their significance of subspecies identification 本文克隆并测定了13只东北虎mtdnad - loop区381bp的序列，并对这些序列和genbank中注册的2个东北虎d - loop区序列和32个虎cytb基因全序列(包含4个亚种)进行了分析，研究了cytb基因和d - loop区序列的特点及其在亚种识别中的价值。
