查询词典 petrogenic

These ages are concordant, such that represent the petrogenic age of the two units , respectively.

两组年龄数据谐和|性较好，可代表两个单元岩石或岩体的成岩年龄。

The results indicated biogenic conversion, petrogenic and pyrogenic were three important sources of PAHs and their contributions were 19%, 24% and 57%, respectively.

由于长江口距离燃烧源较远，与周边的城镇相距甚远，所以长江口表层沉积物中高环多环芳烃含量相对较低，以石油源PAHs污染为主。

At other locations, both petrogenic and pyrogenic inputs were significant.

污染程度差异大。

Source apportionment results exhibited that pyrogenic and petrogenic source were two major sources of PAHs, the contributions of which were 92.1% and 7.9%, respectively.

上海市表层土壤中多环芳烃污染源主要有燃烧源和石油源，以燃烧源污染为主，占92.1%，石油源污染仅占7.9%。

PAHs source analysis suggested that, in the Yangtze Estuary, PAHs at locations far away from cities were mainly from petrogenic sources.

上海市主要水体(长江口、黄浦江和苏州河口)表层沉积物中总PAHs浓度为107～7，177ng/g-dw。

Statistics analysis and some diagnostic ratios were used for source identification and the contribution rates of main sources were also calculated. Pyrogenic PAHs and petrogenic PAHs accounted for 70.97% and 11.38% and 64.93% and 14.11% respectively. PAHs in the road dusts from Shanghai urban area were mostly generated by incomplete combustion.

结果表明，不完全燃烧来源和石油类产品泄漏来源的贡献率分别为70.97%、11.38%和64.93%、14.11%；上海市中心城区地表灰尘中PAHs主要来源于各类矿物燃料的不完全燃烧，而且主要来源于当地污染源。

Source identification results showed that PAHs in surface sediments along the Yangtze estuary mainly came from incomplete combustion while PAHs in surface sediments from the Chongming island were mostly petrogenic PAHs.

来源辨析结果表明边滩表层沉积物PAHs主要来源于不完全燃烧，崇明低潮滩显示出较强的石油类产品泄漏来源的特征。

Pyrogenic PAHs and petrogenic PAHs accounted for 70.97% and 11.38% and 64.93% and 14.11% respectively. PAHs in the road dusts from Shanghai urban area were mostly generated by incomplete combustion. In addition, local pollution sources were the main sources.

结果表明，不完全燃烧来源和石油类产品泄漏来源的贡献率分别为70.97%、11.38%和64.93%、14.11%；上海市中心城区地表灰尘中PAHs主要来源于各类矿物燃料的不完全燃烧，而且主要来源于当地污染源。

Ratios of AN/and Flur/calculated suggested that PAHs in Qiantang River were mainly from petrogenic origin and the contribution of petrogenic PAHs was decreasing during the last two years.(2)The input and output of PAHs in estuary section of Qiantang River were 21.83 t/yr and 13.49 t/yr,respectively.The input of PAHs was higher than output of PAHs,which caused the increase of concentrations of PAHs in Qiantang River.

2钱塘江河口段15种PAHs的输入通量约为21.83 t/yr，其中干沉降输入约为0.41 t/yr，湿沉降输入约为0.78 t/yr，地面径流输入约为8.50 t/yr，上游输入约为12.14 t/yr，下游输出通量约为13.49 t/yr，输入输出通量之差为8.34t/yr，输入通量高于输出通量，导致水体中PAHs浓度逐年升高。

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。

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
