查询词典 PAHs

The results showed that: low molecular weight aromatic, such as naphthalene, fluorene, acenaphthene, locates at low levels, while the high molecular weight aromatic locates at high levels, such as benzo perylene, indene [1,2,3-cd] pyrene, benzo fluoranthene and benzo pyrene, of which , the concentration of fluoranthene is highest, reaching about 19%.

结果表明：萘、芴、苊等低分子量芳烃的含量相对较低；苯并苝、茚并[1，2，3-cd]芘、苯并荧蒽、苯并芘等高分子量芳烃的含量相对较高；含量最高的单体为荧蒽，占待检的16种PAHs的19%以上。

The addition of alkyl groups to PAHs enhances the carcinogenic potential of these compounds.

烷烃加在多环芳烃上的系列会提高这些化合物的致癌作用。

From the three exposed way, inhalation, take-in and skin absorption, it was found that intake is the main exposed way for Dioxin and PAHs. For Dioxin, the carcinogenic risk of the male is 6.79×10-6 and is 6.44×10-6 for female. For PAHs, the carcinogenic risk of the male is 2.83×10-6 and is 2.73×10-6 for female.

吸入、摄入及皮肤吸收为人体三大暴露途径，本研究模拟两污染物结果显示摄入为主要暴露途径，终身致癌风险值皆高於一般风险限值，戴奥辛男性致癌风险为6.79×10-6、女性致癌风险为6.44×10-6；多环芳香烃男性致癌风险为2.83×10-6、女性致癌风险为2.73×10-6。

In addition, NO, calcium and adhesion molecules mediate the processes of angiogenesis. Thus, we chose fluorene, one of PAHs which contain three bezene rings, to study the effect of PAHs on angiogenesis in HUVECs.

而许多文献也指出一氧化氮、钙离子浓度的变化及黏附因分子的表现在血管新生中扮演一种媒介的角色，所以在此我们选取具三苯环的芴来探讨多环芳香烃对於血管新生方面的影响。

Identification of PAHs sources suggests that all up-cores were dominated by petrogenic sources, but all down-cores except for S17 and S18 were dominated by pyrogenic sources or mixed sources. In contrast, biogenic sources were found dominant in S17 and S18 as they were characterized by higher ratio of perylene/Σpenta-PAHs.

各岩心表层皆大致倾向石油来源，随著深度的增加而逐渐倾向石油燃烧来源或石油/燃烧之混合性来源，其中位处峡谷南隅之岩心S17及S18则有较明显之生物性来源贡献。

The relation of PAHs emission and Dioxin emission was discussed from theory and experimentation in this article, and it was indicated that PAHs could possibly synthesize Dioxin as an usher reagent.

本文还从理论和试验分别分析了多环芳烃排放和二恶英排放之间的关系，结果认为两种情况下多环芳烃都可能成为合成二恶英的前驱物。

For PAHs are liable to be sorbed by soil solids, the plant and microbial availability of PAHs in soils is a major limiting factor of phytore-mediation efficiencies.

植物修复及其强化技术在土壤多环芳烃等有机污染修复中有较大的应用潜力。

There are more than 100 different PAHs.Most PAHs do occur alone in the environment.

绝大多数的多环芳烃在环境中不是单独存在，它们往往是两个或更多的多环芳烃的混合物。

There are more than 100 different PAHs.Most PAHs do occur alone in the enironment.

绝大多数的多环芳烃在环境中不是单独存在，它们往往是两个或更多的多环芳烃的混合物。

Most PAHs do occur alone in the environment. Rather they are found as mixtures of two or more PAHs

绝大多数的多环芳烃在环境中不是单独存在，它们往往是两个或更多的多环芳烃的混合物。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
