ELISA and CsCl- isopycnic ultracentrifugation purification products in each fraction indicated that the particle densities of the fraction with higher rHBcAg antigenicity mainly distributed at the densities of 1.27g·mL-1 and 1.40 g·mL-1, respectively.

The results show that the optimal value of CoCl2 concentration is 0.2 mol/L and the maximum adsorbed amount is 19.674 mg/g onto this adsorbent. The adsorption capacity of phosphine onto CoCl2-modified ACF decreases with the increase of temperatures. The maximum absorbed amounts are 19.674 mg/g at 298 K, 13.537 mg/g at 313 K and 11.087 mg/g at 328 K, respectively. It is found that the Freundlich equation is more suitable for the description of phosphine adsorption process than the Langmuir equation. The isosteric heat of adsorption decreases with the increase of the surface loading on CoCl2-modified ACF, which means that CoCl2-modified ACF adsorbent has an energetically heterogeneous surface. Meanwhile, adsorptive phosphine removal performance may be a dominant of physical adsorption when the heat of adsorption is 16-24 kJ/mol, the CoCl2-modified ACF adsorbent will be one of the candidates for tail gas purification of airtight calcium-carbide furnace and recycle of phosphine.

研究结果表明：浸渍液浓度最佳值为0.2 mol/L，此改性ACF对PH3的饱和吸附量为19.674 mg/g；PH3在CoCl2改性ACF上的吸附量随温度升高而迅速降低，在298，313和328 K时PH3的饱和吸附量分别为19.674，13.537和11.087 mg/g；Freundlich吸附等温方程较好地模拟了PH3在改性ACF上的等温吸附；PH3气体在改性ACF上的等量吸附热随吸附量的增大而减小，表明改性ACF吸附剂表面能量的不均匀性；吸附热在16~24 kJ/mol范围内，过程为物理吸附，有利于密闭电石炉尾气的净化。

"Imagination of community" that the pursuit of Judaistic purification lifestyle values is international by nature, enabling itself to contact in the context of post-modernism with the connotation of Christian "outlook on the God"(post-modernistic). The "dialog" between the two religious entities realizes the possibility of attaining "imagination of community" about prevision of future life, and this scenario provides beneficial ideological reference for the future of the entire humanity.

犹太教基于&纯洁化&的生活形式的追求而指向的&共同体想象&就其本质而言具有世界性意义，这一点使其在后现代视野中具有了与基督教&上帝观&之内涵达成沟通的可能，即通过二者之间的&对话&具有达成关于未来生活设想的&共同意见&的可能性，而这可以为后现代社会下的人类整体未来走向提供有益的思想借鉴。

In comparison with π-conjugated polymers, mono- disperse conjugated oligomers possessing well-defined con- jugation lengths and structural models are characterized by the uniformity, absence of chain defects, and ease of purification and characterization, which make them superior to CPs for systematic investigation of the structure-property relationships.2

The optimal conditions were as follows: molar ratio of lauric acid to phytosterols 1.4:1, reaction temperature 120℃, SDS 1.5% and reaction time 4 hours. Under this condition, the yield of esterification reached 87.9%. After three steps of purification the content of phytosterol ester is about 93.1%. The product was determined as phytosterol laurate with FT-IR.

Under lab condition.［Result］ TN and TP concn. in the sewage were decreased constantly with the increase of duckweed treating time in 0-10 d. The purification ability of Spirodela Schleid on TN and TP was higher than that of Lemna L. The maximal removal rates of duckweed on TN and TP in sewage diluted at 5 times were 71.14% and 81.00% resp. and that in the sewage diluted 10 times were 92.18% and 91.33% resp.

结果］ 污水TN和TP浓度随浮萍处理时间（0～10 d）增加而持续降低；紫萍属浮萍对TN和TP的净化能力优于浮萍属浮萍；浮萍对稀释5倍的供试污水TN和TP的最大去除率分别为71.14%和81.00%；浮萍对稀释10倍的供试污水TN和TP的最大去除率分别为92.18%和91.33%。

Again, if a Jew who had become Levitically defiled, required immersion, it is difficult to suppose that a heathen would have been admitted to all the services of the Sanctuary without a similar purification.

同样，如果一个犹太人谁已成为Levitically污损，需要浸泡，很难设想，一个异教徒将被接纳为所有的服务区没有类似的净化。

In this work, the degradation process, mechanism, kinetics as well as the separation and purification of levulinic acid production from biomass, such as wheat straw and wood powder, were evaluated at high temperature and catalyzed by acid.

本文以麦秸和木屑等木质纤维素类的可再生资源为原料，对在高温及酸存在的条件下降解制备乙酰丙酸的工艺条件、生成机理、反应动力学及提取工艺进行了研究。

The traditional separation and purification process of levulinic acid was consisted of solvent extraction and high vaccumn distillation, which was low in product recovery, high in energy consumption and complex in process operation.

传统的乙酰丙酸分离提取工艺以有机溶剂萃取和真空精馏为核心，乙酰丙酸的回收率低、能耗高、工艺复杂，成了制约工业化生产的主要因素。
