Results showed endothelialcells inoculated by shimen virulent strain of CSFV have no obvious change after 12h,24h;At36h,cells become be elongate and appearanced defluvium;At 48h,a few of cells started tobecome round and intercellular space become auxesis;At 72h, intercellular space becomemore auxesis, defluvium of cells was acute.

结果表明，血管内皮细胞于接种 CSFV 石门株后 12h，24h 无明显变化，至 36h 时，细胞开始拉长，个别细胞开始脱落；至 48h 时，部分细胞变圆，脱落，细胞间隙增大；至 72h，细胞拉长呈长梭状，细胞间隙很大，细胞脱落严重。3 个对照组的细胞均未出现明显变化。

It was demonstrated that SARS-CoV was a new coronavirus which had not been found in human and animal and no cross-reaction with human susceptible strains HCoV-OC43 and HCoV-229E.

研究表明，SARS-CoV与人类普遍易感的冠状病毒OC43和229E株无抗体交叉反应，是一种新的从未在人类或动物中发现过的冠状病毒。

Sequences analysis revealsthat these 54 strains have as high as a 99% similarity in 16S rRNA gene level. Allthese 54 strains could be classified into six subgroups according to six differentregions on full-length 16S rRNA gene. Even if the regional differences are not evidentto distinguish B. thuringiensis from B. cereus, however the data of the 16S rRNA genesequences will serve to broaden the database for Bacillus, and provide someinformation for the classification of genus of Bacillus. Additionally, seven B.

本研究利用通用引物，对54株苏云金芽胞杆菌和蜡状芽胞杆菌的16S rRNA基因进行测序，并对所得到的序列进行简单的分析，发现苏云金芽胞杆菌和蜡状芽胞杆菌的16S rRNA基因的相似性很大，大约为99％，在其全长含有6个区域的不同，根据这6个区域将Bt和Bc分成6个亚群，而Bt和Bc在不同亚群之间交替存在，说明16S rRNA基因上的差异不足以区分Bt和Bc。

This thesis studies each structural layer's feature:(1) structural layer of basement:it is a Paleozoic folded basement,whose tectonic deformation and magma intrusion is fiercely,and it is affected by the early Hercynian tectonic movement and related to the underthrust and closure (C1) of Zhungaer ocean basin and the areal pressing of continents (C2-3);(2) structural layer of Permian:due to the regional extending and fault depression role in mid-Hercynian,it occurred to the combinations of structure and magma in Santanghu basin and it's periphery area,such as A-granite's stock,batholiths and diabase's dike.

In order to investigate whether fragments of Sugarcane bacilliform virus were integrated into Saccharum inter-specific hybrids genome, a DNA fragment homologous to SCBV was amplified from a hybrid sugarcane plant Saccharum inter-specific hybrids var.

为研究甘蔗杆状病毒Sugarcane bacilliform virus的基因组片段是否整合进杂种甘蔗Saccharum inter-specific hybrids基因组，以采自广西甘蔗研究所的1株杂种甘蔗植株叶片总DNA为模板，根据已报道的甘蔗杆状病毒基因组序列设计多条特异引物。

By 16S rRNA. When it was cultured in MMSW substrate, adding MWFO and SWFO as the carbon source, it could produce crude biodemulsifier of 4 g/L and 3.5 g/L respectively. Compared with biodemulsifier produced by paraffine as the carbon source, both of them could achieve higher demulsification ratio in breaking W/O and O/W model emulsion.

的一株破乳剂产生菌，在以废弃油脂MWFO、SWFO为碳源培养下，得到的生物破乳剂的粗重为4 g/L、3.5 g/L；对于W/O、O/W模型乳状液的破乳效果均可超过以液体石蜡产生的破乳剂，且以SWFO废弃油脂培养得到的生物破乳剂可以同时应用于两种模型乳状液的使用。

Inflorescences solitary, axillary, often pedunculate, seated on a receptacle; receptacles at first broadly subcampanulate, soon expanded, of unisexual flowers; male and female inflorescences often separate or sometimes mixed in same receptacle, rarely male ones capitate or cymose without receptacle; involucral bracts in 1 or 2 whorled rows along margin of receptacle.

花序单生，腋生，通常有花序梗，在一花托上坐下；花托最初宽近钟状，不久膨大，单性花（植株雌雄同株或异株；雄和雌花序通常有时分开或在相同花托内混合，很少的雄性头状或没有花托；花托的总苞片1或2轮排在边缘。

In-depth studies were carried out on the extracellular·OH scavenging effect of white rot fungus with various media conditions in the dynamic degrading process of lignocellulose, and on the correlation between·OH scavenging and lignocellulose degradation. The·OH scavenging efficiency of A3 reached 45%~50% significantly during biodegrading process.

对不同白腐菌、丝状真菌及细菌的木质纤维素基质液体培养体系，进行胞外·OH清除能力比较研究，结果表明：体系·OH清除能力在白腐菌类群中较为普遍，相对于细菌、丝状真菌等常见微生物群落则是较独特的，该能力与菌株木质纤维素降解机制及能力相关，受底物基质营养构成状况影响。

In the mating test, mycelial protoplast pairs between single spore isolates of different strains formed colonies with clamp connection, while mycelial protoplast pairs between the same single spore isolates formed colonies without clamp connection, suggesting that the two nuclei of the spores possessed identical mating type factors.

在交配试验中，源于不同菌株单孢分离物的菌丝原生质体的配对形成具锁状联合的菌落，而源于同一单孢分离物的菌丝原生质体的配对则形成无锁状联合的菌落，暗示担孢子中的两个核具有相同的交配型。
