In this paper, a method was established to determine the boiling point distribution of hydrocarbon types in diesel. The diesel sample was separated into the saturate and aromatic fractions by means of solid-phase extraction （SPE）, and each fraction was analyzed by GC/FID-EIMS. According to the relationship between boiling point and retention time of n-paraffins in the chromatogram, the percentages of saturates and aromatics at each temperature interval were calculated. According to the average mass spectra of the saturate and aromatic fractions at each temperature interval, the hydrocarbon types of the sample were identified through summation of characteristic mass fragments. Using this method, the changes in composition of diesel during hydrotreating process were studied. The results showed that hydrogenation of aromatics is the main reaction during the hydrotreating process. The more rings the aromatics have, the easier the hydrogenation reactions would take place. The aromatics were converted into cycloparaffins via the hydrogenation and saturation process, leading to an increase in low boiling point fractions in the hydrotreated oil.

目的观察原发性胃癌患者中EB病毒感染情况和p53蛋白的表达及其临床病理特征。方法原位杂交法检测胃癌组织中EB病毒编码的小RNA,分析EB病毒相关性胃癌的病理形态及患者年龄、性别、肿瘤部位、分期分型、分化程度、幽门螺杆菌感染、HER2表达、Ki-67表达等临床病理特征。使用免疫组织化学法检测胃癌组织中p53蛋白的表达水平,分析其与EB病毒感染的相关性。结果101例胃癌标本中检测出12例感染EB病毒(11.9%),与EB病毒非相关性胃癌相比,EB病毒相关性胃癌分化程度低,远处转移多见(χ^(2)=3.53,P<0.05),EB病毒相关性胃癌中p53蛋白的表达率显著高于EB病毒非相关性胃癌(91.7%∶56.2%,χ^(2)=10.871,P<0.05)。结论与EB病毒非相关性胃癌相比,EB病毒相关性胃癌具有独特的临床病理特征,同时EB病毒相关性胃癌中p53蛋白过表达可能与EB病毒感染有关。

Three different types of VGO were selected and cut into various distillates by true boiling-point distillation （TBD）, and the distillates were further separated into different components （saturates, aromatics and resins） via solid phase extrac- tion （SPE）. The hydrocarbon components in saturates and aromatics were characterized on the quasi-molecular level by GC/ MS and CJC/TOF MS. Cracking reactions of VGO, their distillates, and hydrocarbon components （saturates and aromatics） were performed on an ACE （model AP） unit. Nine correlation parameters （mainly based on the previous assumption of basic structure Units, BSU） which could better reflect the structures and compositions of hydrocarbons were put forward based on the quasi-molecular level analysis data, and correlated with FCC product distribution by multi-regression method. A series of correlation formulas were obtained. The formulas were further verified by comparing experimental and calculated FCC yields emanated from two other VGO feedstocks.

近年来金属有机框架材料(Metal-Organic Frameworks,MOFs)是各研究领域的研究热点,因其多孔、比表面积大及其可调的孔径,易于进行结构修饰,MOFs在吸附分离领域多有应用.使用不同的载体对水体中的罗丹明B(RhB)进行吸附实验,尽可能提高对RhB的吸附率,可大大减少水体中RhB的含量,从而降低其危害性.本研究以均苯四酸官能化的UiO-66-(COOH)_(2)为载体,使用甘氨酸(Gly)和谷氨酸(Glu)对其进行修饰,采用单一变量法改变萃取条件对罗丹明B进行萃取,并运用粉末X射线衍射(XRD)和红外光谱(IR)进行表征,采用荧光分光光度法研究其吸附罗丹明B的能力.

In this paper, a particle filter （PF） with simulated annealing algorithm is proposed to estimate and track Rayleigh channel state information （CSI） using decision directed scheme. By iteratively cooling in PF, there are two superiorities in our proposed algorithm. First, there is no degeneration problem in this method. Second, the proposed algorithm converges globally. The proposed algorithm has been implemented in a system on Rayleigh channel with BPSK modulation. Also, the consistency and sensitivity of the algorithm has been tested and the simulation results show that the proposed algorithm is good enough to be applied to wireless communication practice. The relationships between channel estimation and measurement noise, SNR and Doppler frequency have been shown by simulations.
