  论文首先介绍了关于系统分析、模拟仿真以及ibis模型的一些相关知识及移动平台系统的总体设计方案。
• From 1999 to 2002 , a bird investigation was conducted in the distribution area of the crested ibis , yangxian , shaanxi province . totally 201 species were recorded , belonging to 16 orders , 48 families and 116 genus
  摘要1999年1月至2002年1月，在陕西省洋县进行朱?研究过程中，对当地鸟类进行了长期、系统的观察，记录到鸟类16目48科116属，共201种。
• Some recombinant proteins agreeing with those expected were obtained , including the ngf , nt - 4 and gdnf of giant panda , bdnf and gdnf of crested ibis . the expressed fusion proteins were verified with sds - page , gst activity and western blotting
  利用sds page 、 gst酶活性及western杂交等技术初步证明了所获得的重组表达蛋白为gdnf基因和nts基因家族各成员之编码蛋白。
• The research will predic atively heighten the therapy level for the suffering individuals in captive populations of both the giant panda and crested ibis , and possess great theoretical and practical significances on enhancing the living status of the endangered animals
  这对于促进大熊猫和朱?圈养种群之现有疾病治疗体系层次的提高，改善种群现有的健康状况，具有重要的理论意义和实用价值。
• That means genetic diversity in crested ibises can be sustained , and on the base the populations " adaptive capacity and evolutionary potential should be promoted . in this way , the rare bird will be protected more successfully
  根据谱系而在繁殖酉己付时尽可能地避免近交，将增进个体间的基因交流，使种群的遗传多样性得以维持，并有可能提高其生存能力与进化潜力，最终达到更好地保护这一稀世珍禽的目的。
• Crested ibis ( nipponia nippori ) , a kind of peculiar wading bird in east asians facing its extinction because of humanbeings " economic activities . seven crested ibises found at yong county shaanxi province in 1981 were the all wild individuals left in the world then . to protect this rare bird , scholars have carried out a great deal of researches on it in many areas . however , till now , studies is mainly confined to some areas such as ecology and morphology , little was done in the area of molecular biology . phenomina such as disable individuals increasing and adults " producing ability decreasing occurred more frequent in recent years . these badly affected the existence and development of this species . so , getting the information about crested ibis " gene and genetic diversity through studies at molecular level and setting up scientific producing and protecting projections are becoming urgent tasks
  为保护这?濒危鸟类，我国学者对朱?展开了多方位的研究。然而迄今为止，这些研究主要限于生态学、形态学等方面，分子生物学领域则很少涉及。近年来朱?种群频繁出现诸如残疾幼鸟增多、成鸟繁殖力下降等问题，已严重影响到种群的生存与发展，因此，从分子水平对朱?进行研究，了解其基因信息和遗传多样性，并确定个体之间的亲缘关系，从而制定科学、合理的繁殖计划与保护对策，已成为当务之急。
• Similarity coefficient and genetic distances between two arbitrary individuals were caculated according to the data of experiments , the pedigree was constructed by two means ( they were upgma and parsimony ) , and genetic diversity was discussedbased on selecting the best conditions of pcr with opg and opa primers from operon company , we obtained 163 bands using 24 random primers . in other words , 163 sites in crested ibis " genome were detected . the bands from 23 primers showed polymorphism . minimurn of polymorphic ratio was 0 , maximum was 85 . 71 % , and average was 48 . 99 % . in the population which was composed by 37 individuals , most of genetic distances between two arbitrary individuals were less than 0 . 1 . the results showed that the degree of similarity among crested ibises was high while genetic diversity in the population was low accordingly
  我们在对operon公司opg系列和opa系列引物进行优化筛选的基础上，用24条随机引物共扩增出163条谱带，即检测了朱?基因组中的163个位点，其中23条引物的扩增结果具有多态性；谱带的多态比率最小为0 ，最大为85 . 71 ，平均为48 . 99 ；在由37只朱?组成的种群中，任意两个个体之间的遗传距离绝大多数在0 . 1以下。这些结果表明，目前朱?个体间的相似程度很高，种群的遗传多样性水平较低。
• In the meantime , congenital amblyopia resulted from optic nerve lesion was observed in the crested ibis , with an incidence rate of 3 - 5 % . since the epilepsy and congenital amblyopia are both hereditary , it is feasible to perform genetic engineering studies on the correlative genes , which could protect neurons from the damages of excitation toxin and vision sickness , in order to cure the diseases at gene level
  由于癫痫和视神经病变类疾病均属于遗传性疾病，因此，利用分子生物学技术，对因癫痫和遗传性弱视症导致的神经元损伤具有保护及再生作用，以及视神经通路的发育、分化和受损视觉通路具有修复作用的相关基因，开展克隆、表达和活性鉴定之研究，将为通过基因工程技术实现其疾病治疗之目标奠定基础。
