Because callow birds had not be marked with rings in the early period of protection , the pedigree was confused . so , it is very difficult to carry out artificial pairing . for its reference value to set reasonable breeding plan , the pedigree chart constructed by us can be applied in the protection to crested ibis . according to a good breeding project , inbreeding can be avoided and gene exchange can be increased 由于在朱?保护的初期阶段未能对离巢幼鸟进行环志，故现存朱?的谱系关系混乱，给人工选种配对带来了困难；我们所构建的谱系图可以在一定程度上应用到西北大学硕士学位论文沐潭鸟保护的实际工作中，为合理地制定繁殖考。
Otherwise , in this paper , it will introduce the feature of ic chips , the key point on pcb design , the importance of making signal integrity , and the usage of the ibis modular . it will introduce the knowledge of i2c bus protocol , dsp / bios , usb2 . 0 portocol , windows driver model , dirverworks , and inf 本文对应用器件的功能与特点、 pcb设计的要点、所涉及到的信号完整性分析和ibis模型、 i2c总线协议、 dsp / bios 、 usb2 . 0通信标准、 wdm驱动程序模型、 driverworks开发及inf制作等多方面的知识,进行了简要的介绍。
The main results as follows results from sinoatrial node in vivo 1 、 under bilateral vagi intact condition the value of hf ( high frequency power ) component , lf ( low frequency power ) component and apen value of ibis was the highest , but the lf / hf ratio was the lowest ; unilateral vagotomy decreased apen value of ibis , right vagotomy increased lf / hf ratio but left vagotomy did not 05 ） 。在离体窦房结还记录到自发轻度不规则放电，自发不规则放电使窦房结放电间期近似嫡从对照时的0二8土0 09 （ n 6 ）升高到不规则放电时的0
After purification using glutathione sepharose 4b affinity chromatography and digestion with thrombin , the recombinant ntfs were found to be biologically active in the pc 12 cells neurite outgrowth assay . the assays demonstrated that the purified ntfs proteins exhibited normal activity , which is the first step in developing a comprehensive gene therapy for nerve diseases of the giant panda and the crested ibis 最后，对重组表达蛋白经glutathlonesepharose4bmicrospincolumn亲和纯化后，进行大鼠肾上腺嗜铬瘤细胞（ p2 ）神经营养因子的活性鉴定，发现其能够诱导神经细胞分化产生突触，即具有预期的生物学活性，表明所获表达蛋白为大熊猫nt
Research on the egrets mixed population in xiamen egret natural reserve found that the reserve and its extending area provided the population fitting conditions through winter . the dominating component is little egret ( elpetta garzetta ) and there were some large egret ( egretta alba ) , cattle egret ( bubulcus ibis ) and few chinese egret ( egrtta eulophotes ) 2000 2001年，对厦门白鹭自然保护区的鹭类种群动态研究表明，保护区及其周边地区为鹭类种群提供了优良的越冬条件，越冬鹭群主要包括白鹭和少量牛背鹭与大白鹭，偶见黄嘴白鹭。
Although the gene therapy of the human nerve system diseases are still in exploring so far , and similar studies applied to the wild animals have not even been reported , this study will inevitably provide clues for futher studies on the gene therapy in the giant panda and crested ibis 目前，虽然对人之癫痛与视神经病变类疾病的基因治疗尚处于探索阶段，而动物在此领域的工作尚未起步，但本文所完成的大熊猫和朱鹤神经营养因子（ ntfs ）基因家族的克隆、表达及活性鉴定工作，无疑为后续的深入研究奠定了基础。
Because of the method is convenient and fast , and no molecular information about the species to be studied is needed , rapd is widely used in many areas such as study of phylogenetic tree and genetic diversity . we studied 32 crested ibises from yong county and 5 crested ibises from beijing zoo by rapd 我们采用rapd技术对来自洋县的32只朱?和来自北京动物园的5只朱?进行了研究，根据实验数据计算了任意两个个体之间的相似性系数和遗传距离，分别用upgma法和简约法构建出其谱系关系，并对种群的遗传多样性作了初步的探讨。
By the end of 1995 china had set up 175 zoological gardens and zoological exhibition sites in public parks , 227 artificial breeding centers for wild animals , more than 60 large botanical gardens and 255 wild plant gene and cell banks to ensure the continuation of rare and endangered species of plants and animals , including the giant panda , chinese alligator , chinese sturgeon , white - flag dolphin , manchurian tiger , crested ibis , cathay silver fir , dovetree , cycas revoluta and camellia chrysantha tuyama 到1995年底，中国共建动物园和公园动物展区175个、各种野生动物繁殖中心（场） 227个，建立大型植物园60多个、野生植物引种保存基地255个，使大熊猫、扬子鳄、中华鲟、白暨豚、东北虎、朱? 、银杉、珙桐、苏铁、金花茶等珍稀濒危动植物得到保护。
