Bacterial strains were isolated from humus mud by employing the dilution methods. Seven cellulose-degradation Strains marked as B-37, B-35,B-31, B-25, B-17, Z-a, and Z-b were selected according to the hyaloid rings on the medium of carboxymethylcellulose sodium Congo red and their efficacy of decomposing filter paper. Z-b had the strongest ability in decomposing filter paper among the seven strains and 16S rDNA analyzed indecated that it was Stenotroplaomnonas maltophilia owning to 99.8% homology. Comparing clony size of the seven strains in media with different carbohydrates and inorganic salt, we found that the potato extract and inorganic salt which contained CaCl2 0.20, MgSO4 1.25, NaCl5.00,(NH4) SO4 1.30, KH2 PO4 1.35, FeSO47H2O 0.015, Na-EDTA 0.02 were suitable for the bacteria growth.

用稀释法从腐殖泥中分离菌株，根据它们在梭甲基纤维素钠-刚果红培养基上的透明圈直径及对滤纸的崩解能力，获得7株纤维素分解细菌（编号：B-37、B-35、B-31、B-25、B-17、Z-a和Z-b），其中菌株Z-b的纤维素崩解能力最强，分子鉴定结果表明它与Stenotrophomonas maltophilia的16S rDNA序列有99.8%的同源性，初步确定为嗜麦芽窄食单胞菌。

The sufficient and necessary conditions of complete moment convergence for sequence of identically distributedρ-mixing random variables are obtained, which extent and generalize the well-known results.

获得了同分布ρ混合序列的矩完全收敛性成立的充分必要性条件，推广和改进了已有的结果。

The scaling effect on transmission spectrum with increasing Fibonacci sequence is obtained at the quarter-wavelength optical thickness.

计算了随Fibonacci序列长度而变化的标度因子，并用FDTD模拟证实了表面等离子模场的局域性。

An enriched PCR fragments with less complexity were obtained and mainly expressed in the denervated hippoampus After cloning into the plasmid vector, 46 clones were initially screened and subjected to autosequencing By comparison with the EMBO gene databases, 21 gene fragments of different types were obtained with 11 similar to genes of known function and 10 similar to ones of unknown function It is inferable that the altered gene expressions of hippocampus following the entorhinally denervation may underlie the specfic reinnervation and the formation of synapses by transplanted entorhinal neurons with host neuropil within the denervated target areas.

初步挑选出的46个转化后的阳性克隆，经点杂交筛选和基因序列分析，与Gene Database同源性比较后，得到21种基因片段，其中功能已知的有11种，功能未知的有10种。结果表明海马在去内嗅皮层后某些基因表达的改变，这可能是移植胚胎内嗅皮层神经细胞轴突特异支配去神经靶区和重建突触联系有关。

A few necessary and sufficient conditions with uniform integrability of B-valued random elements are obtained.

进而得到了B值随机元序列一致可积性的充要条件。

These variations may have some effect on gene structures and gene expression, and then contribute to intraspecific phenotypic diversities.

在物理图提供的序列基础上，对于籼粳稻两个主要栽培稻亚种进行了比较基因组分析，在2.3Mb对应区段中发现了两个亚种在基因组成和顺序上存在的广泛的微共线性，两者之间的差异主要由插入/缺失和单核苷酸多态性造成，这些差异可能影响基因的结构和表达，从而对种间表型差异产生影响。

In this paper,the system is specified in EFSM model.The concept of invertibility is introduced and used to optimize the transition executability analysis method,so that shorter test sequences can be generated and smaller space is needed to generate the TEA tree.

文中以EFSM为协议的描述模型，引入了逆向判定性的概念，并利用这一概念对转换可执行性分析方法进行了改进，缩短了生成的测试序列的长度，并且减小了所需的TEA树扩展空间。

After sequenced the band, we found that no fragment is isogeny with it in NCBI date base. It shows that the DNA fragment was a new cucumber DNA sequence.

将p63-m51-384特异条带进行测序，采用NCBI的Blast软件对GeneBank中的非冗余数据库(GeneBank+EMBL+DDBJ)进行查询，没有发现与该标记片段同源性高于30%的片段，说明该片段为新发现的黄瓜序列。

objective to obtain the diffusion tensor maps of the normal human brain,and assess intrinstic properties of water diffusion in quantitative parameters for an anatomic analysis.methods maps of isotropic apparent diffusion coefficient and various anisotropic maps were calculated in60healthy adults from seven diffusion imagings by using single-shot echo-planar diffusion-weighted sequence.brain parenchyma anatomy was analyzed and adciso and various anisotropic index were measured.results （1）diffusion properties of different tissues and anatomic areas of normal adult human brain are different.diffusion in white matter is anisotropic;diffusion in gray matter is isotropic.

目的 获取正常人脑组织扩散张力性图像（diffusion densor imaging，dti），定量分析正常人脑组织水扩散的内在特性，进一步评价脑解剖结构。方法 60例健康正常人，应用单次激发epi-dw序列，计算出adciso图及各向异性图，分析脑实质不同区域的解剖结构，测量adciso（isotropic apparent diffusion coefficient）及各向异性指数。结果（1）脑内不同组织结构弥散特性不同，脑白质弥散表现为各向异性，而脑灰质弥散表现为各向同性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
