查询词典 concentration of

These results suggested that higher concentration of NaCl could cause the seed dormancy and accelerate the germination of ungerminated seeds. Perhaps there was a mechanism that the seed coat or embryo could prevent Na~+ from entering into the embryo so as to keep higher K~+ and lower Na~+/K~+ in the embryo. And it might be one of the physical mechanisms that the seed of Hibiscus hamabo Sieb.et Zucc. could resist high salinity stress. In addition, the annual seedlings of Hibiscus hamabo Sieb.et Zucc.

上述结果表明：高浓度的盐可以诱导海滨木槿种子休眠并促进盐胁迫解除后种子的萌发，这种机制可以使之避开不良的萌发条件，等到降雨使土壤溶液浓度降低再萌发，这是盐生植物的种子适应盐渍生境的一种有效方式；海滨木槿的种皮有阻挡Na~+进入胚的作用或胚具有某种拒Na~+的机制，使胚保持较高含量的K~+和较低的Na~+/K~+，这可能是海滨木槿种子耐盐的主要生理原因之一。

The mc2155 carrying pMind-glmU-AS was induced by different concentration of tetracycline, and GlmU protein was detected in the mc2155 carrying pMind-glmU-AS by Western blotting. The results showed that tetracycline of 20ng/ml has obviously inhibited the growth rate of mc2155 carrying pMind-glmU-AS, but the amount of GlmU protein did not change compared to that of uninduced mc2155 carrying pMind-glmU-AS.

glmU反义RNA的诱导表达与GlmU蛋白的检测分别用5 ng/ml、10 ng/ml和20 ng/ml的四环素诱导携带pMind-glmU-AS表达载体的mc~2155菌株表达反义RNA，绘制细菌生长曲线，结果表明20 ng/ml浓度的四环素可抑制mc~2155/pMind-glmU-AS的生长，但Western Blotting分析结果显示经四环素诱导和未诱导的mc~2155/pMind-glmU-AS中，GlmU蛋白表达量无明显的变化。

The effective concentration of added Ni causing 50% inhibition（EC50）ranged from 11 to 932mg·kg-1 in leached soils which were leached using artificial rain water, and from 7 to 2055mg·kg-1 in unleached soils for the tomato test, respectively, and the ratios of maximum to minimum of EC50 for leached soils and unleached soils were 85 and 294. Soil pH was the main factor controlling the toxicity of Ni in these soils.

在供试淋洗（使用模拟的人工雨水滤洗定量的土壤样品）和非淋洗土壤中，Ni对西红柿生物量50%抑制的毒性阈值（EC50）范围分别从11mg·kg-1到932mg·kg-1和从7mg·kg-1到2055mg·kg-1，其最大值和最小值比例分别达到了85和294倍。

Membrane scaling is caused by the deposition of unsoluble salts as feedwater is converted to brine. In this process the ion concentration of calcium, magnesium and so on increases greatly which will lead to that the ion product of sparingly soluble salts exceeds its solubility product, and the unsoluble salts deposite on the surface of RO membrane to form membrane scaling.

在反渗透海水淡化过程中，由于膜的浓缩作用，浓水中的钙、镁等离子浓度大大增加，从而使难溶盐的离子积大于其溶度积，在反渗透膜表面形成膜垢，影响整个反渗透装置的正常运行，缩短了反渗透膜的使用寿命。

The results show that concentration of ownership has a significant impact on risk-taking. The higher the largest shareholder's shareholding percentage, the higher the risk-taking is; the higher the top five shareholders' shareholding percentage, the lower the risk-taking is. The percentage of untradeable shares, the size of the board of directors, the proportion of independent directors and the average remuneration of top 3 senior executives with the highest remuneration are negatively correlated to the risk-taking. However, the situation that the chairman or vice chairman concurrently holds the post of president or CEO increases the bank's risk exposures to a certain extent. Proportion of state-owned shares, the nature of the largest shareholder and the executives' shareholding have no significant impact on risk-taking.

结果表明，股权集中度对风险承担产生了显著的影响，其中第一大股东持股比例越高风险承担越高，而前五大股东持股比例越高风险承担越低；非上市流通股比例、董事会规模、独立董事比例以及薪酬最高的前三名高管的平均薪酬均与银行风险承担负相关；银行董事长同时兼任行长在一定程度上倾向于增加银行的风险承担；国有股比例、第一大股东性质和高管持股状况没有对风险承担产生显著影响。

It is necessary for two kinds of controlled cooling processing to possess air cooling phase to separate ferrite from austenite, and, by means of this, polygonal ferrite forms, the carbon concentration of the retained austenite untransformed increases and results in the stability of retained austenite increased.

在二种冷却方式轧后控冷的过程中，必须有一个α/γ二相分离的空冷阶段，使多边形铁素体形成，未相变奥氏体中碳浓度增高，其稳定性增强。

The findings of the newly identified goose paramyxovirus strain GPMV/HBexperimental infection were as follows: The challenge caused high morbidity and highmortality.The clinical signs included severe depression, decreased appetite or anorexia,white,yellow and green diarrhea, with neural symptoms;pathological changes showed thathaemorrhage and ulceration of intestine mucosa, necrosis of spleen and pancreas,andedema of liver and kidney, uratic deposition in kidney.Eosinophilic inclusion bodies werefound in the cytoplasm of pancreas and a large quantities of fiber protein were found inintestine. Lots of hemosidefin was found in some area of liver and kidney. A number ofT、B lymphocytes reduced sharply in spleen,lymph nodes in dead geese. Transmissionalelectron microscope showed that some cells had the morphological characteristics ofmitochondria swelling, morphological changes were condensation of nuclear chromatininto dense masses,followed by its marginating against the nuclear envelope, andespecially concentration of cytoplasm association with lots of lipid droplet.

人工感染雏鹅实验中，雏鹅临床表现为高发病率和高死亡率，食欲和饮水减少，拉白色、黄绿色稀粪，伴有神经症状；常规组织学观察，脾脏和胰腺肿大，有白色坏死斑点，肠道出血和坏死，肝脏肿大变性，肾脏肿大变性有尿酸盐沉着等；用特殊染色和组织化学方法首次对人工感染鹅副粘病毒的雏鹅的重要脏器进行研究，结果表明：胰腺中发现病毒包涵体，肠道中大量纤维素以及胶原纤维增生，肾脏、肺脏大量含铁血黄素沉着，免疫器官如脾脏和淋巴结中T、B淋巴细胞大量减少；电镜下多种细胞呈现线粒体水肿，多种实质细胞的染色质固缩，染色质边集，特别是细胞内容物如脂肪滴增多的病理变化特征。

When the concentration of NaCl was further increased to 8%, the cells of P. chrysosporium were deformed and plasma was completely vacuolated, indicative of a severe damage of P. chrysosporium. The DNA similarity was reduced to blow 67% and the rate of abnormal cells was increased to about 90%. The cells of P. chrysosporium thus essentially lost their original structure and function.

chrysosporium的结构与功能产生不良影响；NaCl浓度≥8%可对黄孢原毛平革菌产生严重损伤，细胞变形严重，空泡化，DNA相似度降至67%以下，异常细胞量约90%，表明此浓度范围可使黄孢原毛平革菌基本丧失了原有的结构与功能。

The major phase of both slags produced from air and CO/CO2 conditions were SiO2 and Fe2O3, which have much benefit to the encapsulation of heavy metals. The leaching concentration of zinc in CO/CO2 reducing condition is an order less than that in air oxidizing condition due to the higher vapored heavy metals in CO/CO2 reducing condition compared to that in air oxidizing condition. Furthermore, the leaching rate of heavy metals in both CO/CO2 and air conditions are almost the same.

在熔渣特性改变方面，空气气体与CO/CO2还原气氛下所得之熔渣除外观上不同外，两种熔渣之XRD之图谱因熔渣之结晶程度不良，仅可鉴定出SiO2及Fe2O3两种晶相，因而熔渣中之SiO2及Fe2O3可视为较为稳定之晶体结构，故在还原气氛熔融时，对熔渣中重金属之匣限化仍具有正面助益。
