The difference in oxygen absorption stable performances of different diesel fuels can be accurately and easily seen by the oxygen absorption stable index ...

本文提出的吸氧安定性因子能够准确反映出不同种类柴油在吸氧安定性能方面的差别，可用以评价柴油的吸氧安定性能。

Our results suggest that COX-2 activity is involved in ethanol-induced HCV-RNA and NS5A protein expression, because acetylsalicylic acid, a COX-1/2 inhibitor, blocked this induction and downregulated COX-2 protein expression and activity.

研究结果表明，环氧合酶-2活性，涉及酒精介导的丙型肝炎病毒核酸及ns5a区蛋白表达，因为环氧合酶-1 / 2抑制剂——乙酰水杨酸，可阻断这种诱导机制，并下调环氧合酶-2蛋白的表达和活性。

In nutrient solutions,deoxygenation caused a series of changes in root ana-tomy of some species,such as increased root diameter,root porosity and more developed aerenchyma,inducing a ROL barrier in root basal part and the consequent change of ROL profile.

溶液培养条件下，缺氧胁迫能使植物根的直径增粗，根孔隙度提高，通气组织更加发达，诱导根基部泌氧屏障的生成，使泌氧速率和泌氧方式发生变化。

These catalysts were employed in the HKR of epichlorohydrin, styrene oxide and phenyl glycidyl ether.

研究了其对环氧苯乙烷、环氧氯丙烷以及苯氧基环氧丙烷等的水解动力学拆分的催化作用。

The observed EMF values of oxygen concentration cellcoincided with theoretical values perfectly, indicating that it was purely oxide-ionicconductor with oxygen ion transference number of 1. It was shown to have the oxide ionicconductivity of 0.03 S·cm~(-1) at 1000℃.

氧浓差电池电动势的实测值与理论值吻合得很好，氧离子迁移数为1，表明该样品在该温度下氧气气氛中为一纯氧离子导体，1000℃时样品的氧离子电导率为0.03S·cm~(-1)。

The maximal conductivity of the ceramic is 3.2×10－2 S·cm－1 in O2 at 1000 ℃. The conduction in the ceramic is purely oxide-ionic with oxygen ion transference number of 1 over the whole temperature range of 600～1000 ℃. This ceramic is obviously superior to YSZ ceramic in oxygen pump performance.

结果表明，该陶瓷样品在600～1000 ℃下氧离子迁移数为1，氧离子电导率的最大值为3.2×10－2 S·cm－1，是一个优良的氧离子导体；它的氧泵性能明显地优于YSZ。

In this study,cardiovascular-pulmonary bypass was established on rabbits that were then exposed to oxygen and NO mixture supply of different concentrations,and then the corresponding blood oxygen saturations were determined with the new oximeter and compared with series-wound Baite saturation meter and blood-gas analysis.

测不同氧浓度时的血氧饱和度，同时记录反射式血氧饱和度监测仪、串联的百特饱和度监测仪及血气分析值的血氧饱和度数值。

Abstract］ The isolation and identification of anaerobic bacteria are often difficult because most of them grow much slower than the facultative or aerobic bacteria.

摘要］ 目前厌氧菌的致病性及其相关研究备受关注，但厌氧菌难培养且时间较长，造成厌氧菌的培养、鉴定和厌氧菌感染的诊断非常困难。

Efficacy rates for metoclopramide 10 mg, metoclopramide 20 mg, and metoclopramide-erythromycin were 55%, 62%, and 79%, respectively (P or =.03). Metoclopramide failure occurred in 54% of patients with TBI compared to 35% of patients without TBI, respectively (P or =.02), due to a greater prevalence of tachyphylaxis.

甲氧氯普胺10mg，甲氧氯普胺20mg和甲氧氯普胺—红霉素联合应用的有效率分别为55%，62%和79%（P.03）。54%的合并TBI患者和35%不合并TBI患者由于快速耐受使用甲氧氯普胺无效（P.02）。

In chapter four it is pointed out that the difficulty of measurement in low oxygen range was cause from the Nernst's law own. The reference electrode the surface state of electrolyte and "two layer electrolytes" were considered to find a way to raise the accuracy of low oxygen measurement. It had been found that the ZrO〓 solid electrolyte with a coating of ZrO〓 is appropriate for the determination of low oxygen range.

在第四章中首先分析了定氧技术在测量低氧含量时的困难，指出正是Nernst定律本身限制了低氧测量的准确性；然后分别从参比电极、电解质表面状态和&双电解质法&方面进行了研究，得到了适合于低氧含量测量的传感元件——带有ZrO〓涂层的ZrO〓固体电解质。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
