A clone from each genotype was randomly selected as representative for sequencing. The obtained 16S rDNA gene sequences had a similarity of 87%-100% with those in the GenBank (www. ncbi. nlm. nih. gov), and more than half of them had a similarity lower than 97%, being of new species. Based on phylogenetic analysis, the bacteria in the two soils were classified into 10 groups, with 5 groups in common. The dominant bacterial groups in the two soils differed obviously. In primeval forest soil, the dominant group was Proteobacteria, which had 39 genotypes, occupying 58.0% of all the clones; while in the soil of degraded ecosystem the dominant groups were Acidobacteria and Proteobacteria, which had 19 and 15 genotypes occupying 32.5% and 30.5% of all the clones, respectively. In the soil of degraded ecosystem, Proteobacteria group decreased while Acidobacteria group increased markedly, compared with those in primeval forest soil.

从每种基因型中随机选择一个克隆子作为代表进行测序分析，所有序列与GenBank数据库中序列的同源性为87%~100%，且两样地中均有超过一半的基因型序列与数据库中已知序列同源性低于97%，属于分类在"种"地位上的新发现细菌；通过系统发育研究将两样地的细菌分为10大类群，两样地共同拥有5大类群，但两样地的细菌优势类群明显不同，原生土壤为Proteobacteria，含39种基因型，占总克隆子数的58.0%，退化生态系统土壤为Acidobacteria和Proteobacteria，分别含19种和15种基因型，占总克隆子数的32.5%和30.5%；与原生土壤细菌类群相比，退化生态系统土壤Proteobacteria类群明显减少，Acidobacteria类群明显增加。

The conclusions were as follows: theνO-H andνC=O IR absorption maxima shifted towards higher wave numbers after imprinting 17β-estradiol on TFMAA-co-TRIM copolymer with the red shift of theνO-H groups being apparent after precipitation polymerization for 16h while that forνC=O groups being observed after polymerization for 24h. A strong interaction between TFMAA and 17β-estradiol was confirmed by the high selectivity for 17β-estradiol, as indicted by the values of the separation factor of isomers of 17β-estradiol/17α-estradiol (2.28) and the imprinted factor (3.01). Particle diameter of TFMAA-co-TRIM polymer was between 300 nm and 1.5μm, which suited well for solid phase sorbent throughout at low column pressure. The recognition of imprinting TFMAA-co-TRIM polymer for sterol molecules was driven by enthalpy eluted with acetronitile, and low temperature was in favor of the separation of sterol structure analogues on imprinting column. TFMAA-co-TRIM polymer possessed of determinate anti-heat stability, with melting point beginning at 255.84℃, Tp=257.40℃, control TFMAA-co-TRIM polymer and imprinting TFMAA-co-TRIM polymer were respectively decompounded at 267.79℃and 343.11℃, and solid micro-extraction noddle prepared by the special polymerization also showed definite recognition for 17β-estradiol by GC/MS detecting at 270℃. By selection of various washing and elution solvents, elution reagents of close polymerization system were of more advantage in template molecules retention and recognition on molecularly imprinted solid phase extraction column. At a certain extent, progesterone, 17α-estradiol, 17β-estradiol and 4-androstene-3, 17-dione could be intercepted on the MISPE column. Especially, MISPE had high selectivity for progesterone, and imprinting TFMAA-co-TRIM polymer could achieve adsorption balance within 50 min by absorption kinetics test for 17β-estradiol. However, MISPE column showed better selectivity and enrichment property for 17β-estradiol than C18 and CSPE columns according to the data from HPLC and GC/MS analyses. Recovery of 17β-estradiol on MISPE column was up to 85.5% while when prime extracting solution of milk powder was sampled, the recovery of CSPE and C18 columns were 43.7% and 30.7%, respectively.

通过研究阐明：紫外聚合产物TFMAA-co-TRIM中的νO-H振动吸收峰在聚合16h后红移，νC=O振动吸收峰在聚合24h后红移；TFMAA-co-TRIM对雌二醇异构体的印迹因子达到了3.01，α为2.28，优于其它功能单体参与得到的聚合物识别特性；TFMAA-co-TRIM聚合物粒径介于300 nm至1.5μm之间，作为色谱固定相具有良好的通量和低的柱压；在乙腈流动相中，TFMAA-co-TRIM分子印迹固定相的分离过程主要被焓驱动，低温有利于分子印迹固定相分离甾醇结构类似物；TFMAA-co-TRIM分子印迹聚合物在255.84℃时开始熔融，Tp=257.40℃，聚合物CP的降解温度在267.79℃，MIP降解温度在343.11℃，制备的固相微萃取头初步经GC/MS 270℃的耐热性测定；不同的洗提溶剂筛选证明了选择接近聚合溶剂的洗脱体系更有利于MISPE发挥识别效应；分子印迹固相萃取柱对孕酮、17α-雌二醇、17β-雌二醇和雄烯二酮都具有不同程度的保留特性，可作为此类化合物的吸附材料，特别对孕酮强保留的富集特性，可作为孕酮的选择性识别吸附剂，其分子印迹聚合物对17β-雌二醇的吸附动力学测定显示在50 min内基本达到吸附平衡，具有作为传感器核心敏感材料的潜力；对比萃取奶粉中17β-雌二醇性能，MISPE柱比非分子印迹固相萃取柱和C18柱具有更高的保留，回收率依次为85.5%，43.7%和30.7%。

While the strict integrity policy of Biba's model can be used to maintain integrity of data in computer systems, the integrity labels of both subjects and objects in a system are always kept static in SIP, which might lead to denial to some non-malicious access requirements and hence decreases the compatibility of applications Dynamic enforcement of this policy is presented, which can increase compatibility of software while keeping system integrity as strictly as SIP can The implementation of...

Biba模型中的严格完整性政策能够有效地保证数据的完整性，但是该政策中主体和客体的完整性标记都是静态不变的，这会限制进程的一些原本合理的活动，从而降低应用程序的兼容性。提出严格完整性政策的动态实施方案，并给出该方案在基于Linux的安全操作系统RFSOS中的实现。该方案既可以保证系统的完整性，又能提高系统的兼容性。实验证明，这种方案对系统的整体效率的影响小于1%。

Secondly, the relevance feedback approach requires relevant documents to be similar to each other. That is, they should cluster. Ideally, the term distribution in all relevant documents will be similar to that in the documents marked by the users, while the term distribution in all nonrelevant documents will be different from those in relevant documents. Things will work well if all relevant documents are tightly clustered around a single prototype, or, at least, if there are different prototypes, if the relevant documents have significant vocabulary overlap, while similarities between relevant and nonrelevant documents are small.

第二，相关反馈方法需要相关文档之间相似，即它们可以聚类，理想地，所有相关文档 term 分布应该相似，相关档即用户标记的文档，同时不相关文档应该与相关文档的 term 分布不同，如果所有的相关文档都很紧凑地聚在一个单一的中心点，或至少有不同的中心点，如果相关文档有明显的词汇重复，同时相关与不相关文档相似性比较小，它才是可行的。

Now keyword search over relational database is becoming a hot research topic in both database and IR area. There are two kinds of popular keyword search systems, while neither of them can give accurate results with high speed. The on-line system can obtain the latest search results while the search speed is low; The off-line system speeds the query processing by means of preprocessing, but the disadvantage lies in expensive cost needed to preprocess again once the database is updated.

关系数据库上的关键词检索已成为数据库和信息检索领域的研究热点之一现有数据库关键词检索系统可分为在线和离线两大类，它们都难以兼顾查询效率和效果：在线系统能够获得数据库最新结果，但速度较慢；离线系统使用预处理提高查询速度，但若数据库更新就要重新执行预处理。

The song kind that some people like is not a kind, as long as it is Orphean accept everything, listen a little while rock and roll, listen a little while lyric, by no means an isolated case, taste is very miscellaneous, can my music box help that cruel pick suitable song?

有些人喜欢的歌曲类型并不是一种，只要是好听的来者不拒，一会听摇滚，一会听抒情的，不一而足，口味很杂，那酷我音乐盒能不能帮助挑选适合的歌曲呢？

But in our insiders control transitional economy, because the shares of the companies with higher information asymmetry are overpriced, the possibility to use long term bank debt is low while if companies of this kind import long tern bank debt, the information asymmetry can be reduced. The benefit of monitoring exceeds the cost so that the corporate governance can be improved which will bring better corporate performance; shares of companies with lower information asymmetry do not get much overprice, the possibility of using long term bank debt of this kind of companies is higher while the benefit is smaller than the cost.

但在我国的内部人控制的转型经济中，信息不对称程度高的公司由于股票在公开市场的溢价程度高，引入长期银行借款的可能性反而小，其实这种类型的公司如果引入银行债务的监督，则会减轻信息不对称程度，债务的监督收益将大于债务的成本，从而带来公司治理结构的改善，最终将带来公司绩效的提升；信息不对称程度低的公司由于其股票在公开市场的溢价程度比信息不对称程度高的公司低，反而更有可能引入长期银行借款，但这种类型的公司引入长期银行借款的成本大于收益，将会导致业绩的降低。
