查询词典 nitric bacteria

Objective To explore the method by centrifugalization to enrich bacteria from cerebrospinal fluid of patients, improving rate of positive cultivation by condensing pathogenic bacteria.

目的：探讨离心浓集脑脊液中细菌的方法，通过浓缩标本中的致病菌来提高其培养的阳性率。

Bacteria which concentration more than or equal to 10~2/ml in CSF can be enriched effectively by means of centrifugalization when the relative centrifugal force is 5753xg and centrifugalization time is 15min and the rate of positive cultivation of pathogenic bacteria in clinical specimen can be improved by centrifugalization with high speed.

Sulfur bacteria Filamentous autotrophic chemosynthetic bacteria that derive energy by oxidizing sulfides to elemental sulfur and build up carbohydrates form carbon dioxide.

硫细菌：是通过将硫化物氧化为单体硫获得能量，可将二氧化碳固定为碳水化合物的丝状化能自养细菌。

T tube drainage was able to decrease bile viscosity effectively.The number of bacteria decreased significantly until 21 postoperative days.The time that T tube is drawn out is on 14 postoperative days.Bacteria may exist in bile continuously and play a role on relapse of choledochitis and bile duct stone.

胆汁中的细菌和粘度升高在胆管结石形成中起协同作用。T管引流能有效地降低胆汁粘度，而胆汁中细菌量在引流术后第3周才有显著减少，临床2周时拨除T管细菌可潜伏下来，对胆管炎和胆管结石的复发可能起作用。

The sulfides released by decay of organic matter are oxidized to sulfur by SULFUR BACTERIA of the genera Chromatium and Chlorobium, and further oxidized to sulfates by bacteria of the genus Thiobacillus.

有机体腐烂后硫化物从中释放出来，先被色素菌属 Chromatium 和 Chlorobium 属的硫细菌氧化成为硫单体，进而被硫杆菌属 Thiobacillus 属的细菌氧化成硫酸盐。

Contrasted with inoculating antagonistic bacteria only, inoculation of Botrytis cinerea had some influence on the colonization of antagonistic bacteria.

与对照相比，接种灰霉病菌对拮抗细菌的定殖有一定的影响。

Commensally bacteria help keep pathogenic bacteria at bay, and in the late 1990s new research was beginning to show that symbionts also contribute to the development of the intestinal architecture.

细菌共生帮助保留致病性细菌在海湾，并且在20世纪90年代末期新的研究开始表示， symbionts也对小肠建筑学的发展有用。

The total number of colony forming units of culturable bacteria and fungi were increased significantly(p.01 in transgenic sugarcane rhizosphere soil, but The total number of CFUs of culturable was not effected. No significantly higher CFUs of bacteria, fungi and actinomycetes resistant to kanamycinwere obtained in transgenic sugarcane soil.

结果表明：转基因甘蔗显著(p.05)降低了土壤脱氢酶的活性，提高了土壤的纤维素酶、蛋白酶和脲酶活性(p.01)，而对蔗糖酶和磷酸单脂酶没有影响；转基因甘蔗显著增加了根际土壤可培养的细菌和真菌数量，但对放线菌影响很小。

Results showed that in the water body of Xizi Lake, annual average of culturable planktonic ammonifiers and nitrogen fixers were 510 and 236 CFU/mL, respectively; Ammonia oxidizers, nitrite oxidizers, nitrate reducers and denitrifiers were 8.5, 16, 587 and 16 MPN/mL, respectively; Inorganic phosphate solubilizing bacteria (1PB) and organic phosphorus mineralizing bacteria were 89 CFU/mL and 37 MPN/mL, aerobic and anaerobic cellulose decomposers were 7 and 5 MPN/mL, respectively.

水体中可培养异养细菌和固氮菌的年平均值分别为510和236CFU／mL，氨氧化细菌、亚硝酸氧化细菌、硝酸盐还原菌和脱氮菌的数量分别为8.5、16、587和16 MPN／mL；无机磷和有机磷分解菌分别为89 CFU／mL和37 MPN／mL；好氧性纤维素分解菌和厌氧性纤维素分解菌只有7和5 MPN／mL。

Statistic indicates that half of the sepsis is caused by Gram-negative bacteria,and that lipopolysaccharide,which release from the cytoderm of Gram-negative bacteria,is considered to be the major molecule which is responsible for the endotoxin sepsis.

统计表明，临床半数的脓毒症是由于革兰氏阴性菌(Gram-negative bacteria)感染引起的，革兰氏阴性菌的细胞壁上的脂多糖(lipopolysaccharide，LPS)，或称为内毒素，被认为是革兰氏阴性菌引起脓毒症的主要作用分子。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
