According to the above study result, the diversity of microorganisms population in the SUFR system is complex and the bio-community formed in the SUFR system is stable. The close relations between abundance of bacteria and nutrients were found. The correlation between heterotrophic bacteria and COD was 0.949. The correlation between organic phosphate bacteria and TP was 0.815. The correlation between nitrosobacteria and NH3-N was 0.909. The correlation between disnitrifier bacteria and TN was 0.653. These inneglectable great factors effecting on phosphorus-uptake and phosphorus-release of phosphorus accumulating organisms are the influent COD、the concentration of DO、the sludge retention time、the temperature. The diversity of organic phosphate bacteria population in the SUFR reactor was complex and there is no phosphate bacteria taking the absolute superiority in quantity. The near-native pure culture method powerfully complement the traditional pure culture technique and enrich culture technique. The sludgy bioactivity is very good in whole SUFR reactor. By the quality of being biochemistry, the anaerobic phase is higher than anoxic phase and the anoxic phase is higher than aerobic phase of SUFR.

通过以上试验内容研究发现，SUFR 系统中的微型动物种群较多，微生物生态系统稳定；系统中微生物的数量与营养盐的含量密切相关，其中总异养菌与COD的相关系数r 为0.949，有机磷细菌与TP 的相关系数r 为0.815，亚硝化菌与NH4+-N的相关系数r 为0.909，反硝化菌的数量和TN 的相关系数r 为0.653；污水生物除磷工艺中进水COD 的浓度、DO 浓度、泥龄的长短、温度都是影响聚磷菌释磷及吸磷效果的不可忽视的因素；SUFR 系统中的磷细菌呈现种群多样化的趋势，没有占绝对优势数量的磷细菌；微孔滤膜近自然培养法是对传统纯培养技术和富集培养技术的有力补充；整个SUFR 反应器系统中污泥的生物活性很好，就可生化性来讲，厌氧反应器大于缺氧反应器大于好氧反应器；按照动力学方程式求出的细胞生长动力学特征值和SUFR 脱氮除磷系统工艺的实测值结果基本吻合。

The giant panda-rabbit interspecies reconstructed embryos were constructed by injection of giant panda somatic cells into the perivitelline space of the enucleated oocytes and fused by electrical stimulation, and the reconstructed embryos can develop to hatched blastocyst stage in vitro. We demonstrated that the nuclear genetic materials in reconstructed blastocyst cells were the same as that of giant panda somatic cells by chromosome count and the existence of characteristic chromosome, which was confirmed by microsatellite DNA analysis later In order to determine the fate of mtDNA of giant panda-rabbit reconstructed embryos, we analyzed the cyt b sequence of embryos at 1 -cell stage, 2-cell stage, 4-cell stage, 8 cell stage, morula stage, blastocyst stage, expanded blastocyst stage and hatched blastocyst stage.

异种克隆大熊猫重构胚是通过将大熊猫成纤维细胞移入日本大耳白兔去核卵母细胞透明带下后经电融合构建的，可在体外发育至孵化囊胚阶段，我们应用一种简便、快速的异种重构胚的鉴定方法，即通过染色体数目和特征染色体的存在初步鉴定出大熊猫-兔异种重构胚的核遗传物质来源于大熊猫供核体细胞（后经昆明动物研究所通过微卫星DNA分析验证了该结果的可靠性）。

In fact, cells with NSCs-like properties are likely to occur throughout the adult CNS, but they are able to give rise to neurons in only a few restricted areas in vivo, i.e., the subventricular zone in the wall of the lateral ventricle and the subgranular zone of the hippocampal dentate gyrus. Very poor regenerative capability of the adult mammalian CNS could be explained as follows: first, theneuronal differentiation of endogenous NSCs may be inhibited by microenvironmental factors present in most areas of the adult CNS.

成年哺乳动物中枢神经系统可怜的再生能力可能主要归结于两方面的原因：第一，成年动物中枢神经系统内的大多数区域存在一些特殊的微环境因素，它们抑制了内源性神经干细胞向神经元方向的分化；第二，内源性神经干细胞的数量太少，不足以形成有效的自我修复。
