以扎赉诺尔半焦为原料，采用硝酸活化、水热活化和浸渍活性组分等改性方法，制备了改性半焦脱硫剂，并用于脱除FCC汽油中的各种硫化物。

With an exception of Mo, most of elements distribute in sialic and sulfide state.

除 Mo 外，绝大部分元素存在于硅铝化合物和硫化物结合态中。

Rubbery, skunky, rotten egg or garlic/onion aromas are byproducts of sulfides, while a barnyard aroma results from a yeast spoilage organism called brettanomyces.

橡胶味，毛皮味，臭鸡蛋味或大蒜或者葱味是硫化物副产物，而霉味起因于酵母有机体损坏。

Gas chromatography ; Solid phase micro-extraction ; Pulse flame photometric detection ; Stenchy sulfides

气相色谱法；固相微萃取；脉冲火焰光度检测器；恶臭硫化物

Gas chromatography with sample-pretreatment by solid-phase micro-extraction and with pulse flame photometric detection was applied to the determination of 6 stenchy sulfides(hydrogen sulfide,carbon disulfide,methanethiol,1,2-ethanedithiol,dimethylthioether and carbonyl sulfide) in polluted air.

应用固相微萃取预处理技术，采用脉冲火焰光度检测器-气相色谱法测定污染空气中硫化氢、二硫化碳、甲硫醇、1，2-乙二硫醇、甲硫醚、羰基硫6种恶臭硫化物。

GCF of observed sites was sampled with standardized filter strips. At the same time sulcular sulphide level in the gingival crevicular fluid, sulcus bleeding index, probing pocket depth and clinical attachment level were measured.

用标准化滤纸条采集观察牙位GCF样本，记录相应位点30'硫化物浓度，同时记录龈沟出血指数、牙周袋探诊深度、牙周附着丧失水平。

For the perovskite LaCoO 3 samples before and after activation sulfurization, the experiments of SO 2 TPD, O 2 TPD, and CO combust ion in the presence of SO 2 showed that the activation sulfurization of LaCoO 3 can inhibit the formation of sulfate.

通过对硫化前后的催化剂进行O2 TPD和SO2 TPD分析，认为CO还原SO2反应机理可能是在一定的温度下，在钙钛矿LaCoO3 上发生CO氧化燃烧反应，在硫化物La2 O2 S上发生CO还原SO2 反应，两者相互促进

Sulfide layer was made on the surface of high speed steel (W6Mo5Cr4V2) by means of low temperature ion sulfurization. The tribological properties of the sulfide layer under dry sliding were investigated on an MM 200 friction and wear test rig. An atomic force microscope and a scanning electron microscope equipped with an energy dispersive spectrometer attachment were adopted to analyze the morphologies and compositions of the original and worn surfaces of the sulfide layer. The phase structure of the sulfide layer was determined by X ray diffraction.

采用低温离子渗硫工艺在 W6 Mo5 Cr4 V2高速钢表面制备了硫化物固体润滑层，在 MM- 2 0 0型摩擦磨损试验机上对渗硫层的摩擦学性能进行了干摩擦试验研究，用原子力显微镜及扫描电子显微镜和 X射线光电子能谱分析渗层表面、截面、磨面的形貌及成分，用 X射线衍射仪分析了渗硫层相结构。

The results indicated that the chemical fraction composition characteristics of heavy metals are different. Cu mainly existed in organic/sulphidic fraction and residual fraction; Pb mainly existed in carbonates, Fe-Mn oxides and residual fraction; Cd mainly existed in carbonates and Fe-Mn oxides fraction; Cr mainly existed in residual fraction.

结果表明，不同重金属在消落区沉积物中形态分布各异，Cu主要以有机物及硫化物结合态和残渣态形式存在，Pb主要以碳酸盐结合态、Fe-Mn氧化物结合态及残渣态存在，Cd主要以碳酸盐结合态、Fe-Mn氧化物结合态存在，Cr主要以残渣态存在。

The coating can be divided into two kinds as per light － retaining pigments: sulphuret series and aluminate series. Its feature is to shine after excited by light while afterglow decreases along with time gone.

该类涂料按所用的蓄光颜料分为硫化物系和铝酸盐系2大类，其特性为被光激发后能发光，余辉随时间延长而减小。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
