查询词典 polycyclic

To investigate the distribution and content of polycyclic aromatic hydrocarbons in raw coal and gasified products during coal gasification, the air and steam gasification of coal was tested in an atmospheric fluidized bed gasifier.

为了研究煤及其气化产物中多环芳烃的分布特徵，在一台小型常压流化床气化炉上进行了以空气和水蒸气为气化剂的煤气化试验。

PM10 and PM2.5 samples were collected in Beijing city during the spring, summer, autumn and winter seasons. Following the U.S. EPA-610 method, 18 priority polycyclic aromatic hydrocarbons were quantified by GC-MS. The results show that pollution from in haled particles (PM10) was serious and that the finer particles (PM2.5) account for much of the pollutant.

采集了春、夏、秋、冬4个季节的PM10和PM2.5颗粒物样品，参考美国EPA-610方法，利用色谱－质谱技术对美国环保总局推荐的18种优控多环芳烃进行了内标法定量分析，并探讨了多环芳烃的分布特征和来源。

Fat drippings create smoke that is filled with carcinogenic polycyclic aromatic hydrocarbons, or PAHs.

烧烤时滴落的脂肪会产生充满多环芳烃的烧烤烟。

Fat drippings create smoke that is filled with carcinogenic polycyclic aromatic hydrocarbons, or PAHs. When the smoke envelopes the food, it transfers the PAHs onto the surface of the meat. And when meat, chicken and fish are grilled at high temperatures for long periods of time, compounds inside the food react and create heterocyclic amines, or HCAs. HCAs are worrisome because in lab studies they've been shown to trigger breast, colon and prostate tumors in rats and mice.

滴下来的油脂产生的烟雾充满了致癌的多环芳烃，简称PAHs，当烟雾环绕在食物周围的时候，这些多环芳烃也附着在了食物的表面，当猪肉，鸡肉或是鱼肉在长时间的高温烧烤时，这些食物本身所含有的成分产生了化学变化生成杂环胺类物质，简称HCAs，这类物质相当的麻烦，因为实验室研究发现它们会引起大鼠和小鼠乳腺，结肠以及前列腺部位的肿瘤。

Butyric acid,phenol,indol and polycyclic aromatic hydrocarbons are inferredin the solution phase of leachate by GC,and 53% of organic acids,18% of alcohol andphenols,and 7% of alkanes are detected in leachate by GC-MS.The colloidal structure oflandfill leachate is analyzed by determination ofξ-potential and the interfacial tension,whichprovide the basis to pretreatment by the coagulation and treatment by advanced oxidation.

首先测定了垃圾渗滤液的常规水质因子及污染物含量，并采用GC及GC-MS技术对垃圾渗滤液有机相的微观结构进行了分析，由GC谱图解析推断渗滤液的溶液相中含有丁酸或辛酸、苯酚、吲哚及多环芳烃等有机物；由GC-MS解析可知其有机物主要为有机酸，约占53％，其次醇及酚类约占18％，烷烃约占7％。

Samples were collected in lab for civil coal combustion and in field for coke plant and petroleum asphalt, 13 polycyclic aromatic hydrocarbons were determined by GC/MS.

利用模拟实验采集了民用燃煤污染源样品，在现场采集了焦化厂和石油沥青两类污染源样品，用GC MS联用技术测定了样品中 13种多环芳烃。

It was found that the main reason why SBS containing oil was easy to yellow was that there is plenty of polycyclic aromatic hydrocarbon in the extender oil,PAH can easily turned quinones with yellow.Antiyellowing performance of SBS can be only developed in a little extent when antioxidants were added.The anti-yellowing performanc...

研究结果表明，充油SBS产品变黄的主要原因是油品中的稠环芳烃在光氧环境中易转化为黄色的醌，添加抗氧剂对延缓产品变黄的作用不大，通过催化加氢消除填充油中的芳烃或添加适当的光稳定剂可以提高产品的耐黄变性能。
