Three-hundred and ninety-nine fungal isolates were obtained from 686 diseased cotton seedlings and soil samples collected from cotton production areas in Northern Xinjiang by using the conventional method,among which 272 strains of R.solani were identified.Based on Giemsa staining,all strains were identified as multinucleate Rhizoctonia solani .

从新疆北疆棉区采集了典型的棉花立枯病病苗及棉田土标样686份，按常规分离方法分离得到399个分离物，从中鉴定出272个纯化的立枯丝核菌( Rhizoctonia solani Kühn)菌株。

In this paper, adopted augmenting culture in nitrite bacteria culture media and the method of silica gel plate isolation,31 strains of bacteria were isolated from vegetable garden soil of our school. The color reaction test was carried out with Griess reagent and culture fluid, which was regarded as the index to determine producing NO2- or not. 13 strains which color were deep were obtained and they were further rescreened by doing nitrite test. A strain N4(coded N4,the same to the following)with higher rate of nitrosification was picked up after rescreened; A strain B08( coded B08 ,the same to the following) with higher rate of denitrification was obtained after isolated and rejuvenated from our lab conserving mixed denitrifying bacteria culture.

本研究采用亚硝化细菌富集培养基选择培养和硅胶平板分离法，从本校农场菜园土中分离到31株细菌，以格利斯试剂对培养液的反应颜色深浅作为指标衡量其产NO_2~-的多少，经初筛从分离株中筛选出13株格利斯试剂反应颜色较深的菌株，再对这13株菌作亚硝化试验，最终选出一株亚硝化速率较高的菌株(编号为N_4，下同)；另外，通过对本实验室保存的反硝化细菌混合菌液进行分离复壮，筛选出一株反硝化速率高的菌株编号为B_

By use of Overcomplete Representation method of the data, we get a completely new kind of BSS algorithm---Overcomplete BSS algorithm. The biggest advantage of this new algorithm is that it can still do blind separating works when there are more sources than mixtures!

利用数据的超完全表示方法，我们得到了一种全新的盲信源分离算法，其最大的特点就是当源信号的个数大于观测到的混合信号的个数的时候，该算法仍然能够完成盲分离工作，从而将盲信源分离技术的实用性大大提高了。

By singular value decomposition of the separating matrix, we present a novel independent-component-analysis -based contrast function for BSS, which is a generalization of the existing determined and overdetermined ones.

首先从分离矩阵的奇异值分解出发，提出一种新的基于独立分量分析的盲信号分离对比函数，它是现有的正定和超定盲信号分离对比函数的推广。

The comparison for advantages and application scopes of both methods were carried out. The results show that the former is quicker, but the adding amount of oxalic acid needs to be controled in the range of 1.2-1.7 times of theoretical value and the content of iron in the alloy is required to be below 0.5%. While the later is overelaborate, but it can completely separate magnesium from iron with sharp titration end point.

分析对比了两种方法的适用范围，结果表明，草酸分离稀土方法简便快速，但草酸用量需控制在理论用量的1.2~1.7倍，且合金中铁含量要求小于0.5%；氢氧化铵分离稀土方法分析流程比前者长，但可将主要干扰杂质铁分离完全，终点敏锐。

MSCs can be satisfactorily isolated from human marrow with Ficoll Paque reagent and expanded in L DMEM culture medium.

用Ficoll Paque淋巴细胞分离液分离骨髓单核细胞，接种于φ＝100 mL/L FCS的L DMEM培养液，分离培养扩增hMSC的效果最好。

Methods A strain of Propionibacterium acnes from rumen fluid of health cow with permanent rumen fistula under sterile condition was isolated by segregation procedure of anaerobic bacterium and specific medium SLB, and identified by extraction of the genome DNA of isolation bacterium, clone of the 16S rRNA gene, and sequencing of the strain.

无菌采取装有瘤胃瘘奶牛的瘤胃液，按照厌氧菌分离步骤，通过丙酸生成菌株的特异性培养基SLB进行筛选，提取分离菌的基因组DNA，克隆其16S rRNA基因，进行序列测定，分离出一株痤疮丙酸杆菌。
