The experimental results of stepwise ethanol precipitation showed that the yeild represents the increasing trend with increase of the ethanol concentration, their polysaccharides contents have significant changes, and at the ethanol concentration of 30% and 70%, polysaccharides contents are up to maximum. Molecular weights of endopolysaccharides and exopolysaccharides are pockety.

分级醇沉实验表明，各醇沉浓度对应的得率都随醇浓度的升高而呈增加趋势，多糖含量变化起伏较大，醇浓度为30%和70%时所得多糖含量较高，虫草胞内和胞外多糖分子量分布都很不均匀；分步醇沉测定了各部分多糖所占的比例。

The results were as follows:(1) The method that HA was treated by ethanol of 2.5x volume for 20 hours turned out to be the most economic and efficient.(2) Zymolysis combined with deproteinization by chloroform was better than deproteinization by chloroform for several times in yield and purity of HA.(3) HA with purity of 71.1 60/o was obtained by the fermentation with cetylpyridinium chloride.

本文对发酵液中HA的分离提取方法进行对比研究，结果表明采用2.5倍体积的乙醇对HA沉淀，作用时间20小时最为经济合理；采用酶解结合氯仿除蛋白较之氯仿除蛋白，HA的产量和纯度均有所提高；经氯代十六烷基吡啶分级分离后，可得纯度为71.16％的HA产品。

The critics contend that the Book of the Covenant knows nothing of an Aaronitic priesthood (Exodus 24:5); that Deuteronomy mentions priests and Levites without any hierarchical distinction and without any high priest, determines their rights, and distinguishes only between the Levite living in the country and the Levite attached to the central sanctuary; finally, that the Priestly Code represents the priesthood as a social and hierarchical institution, with legally determined duties, rights, and revenues.

评论家认为，此书的盟约一无所知的Aaronitic铎（出埃及记24：5 ）；申命记提到的祭司和利没有任何等级的区分，没有任何大祭司，确定他们的权利，以及之间的区别只生活在列国家和利未连接到中央圣殿；最后，祭司源代码铎作为一种社会和分级机构，依法确定的职责，权利和收入。

So I hope broad netizen is abhorring business of undesirable developer, operation, player while also can give out our rational and responsible sound: Execute a net to swim at once classification, otherwise, the damage of conglomerate form of powerful dance with sth in one's hands and controversy are met always unending.

所以我希望广大网民在痛恨不良开发者、运营商、玩家的同时也能够发出我们理性负责的声音：赶紧实行网游分级吧，否则，劲舞团式的祸害和争论会永无休止的。

All the compounds were isolated and identified from the bituminous coals for the first time, bis(2-ethylheptyl) terephthalate and 18-ethyl-17-(hexan-2\'-yl) docosanoic acid are new compounds.Further more, a Colourless Oil Liquid, a white acerate crystals containing some alkanes, a white tabular crystals consisting of some fatty acid esters and a white powder crystals in which some fatty acids exist were isolated and analysed by GC/MS for the first time.Through this research, a study method of"classification extract of bituminous coal- separation with silica-gel and gelatin column chromatographies- identification of the isolated compounds by FTIR, GC/MS, LC/MS, 1H NMR and 13C NMR analyses"was established and proved to be a practical approach toward separable and non-destructive identification of some organic compounds in bituminous coals for coal chemistry research.

本研究建立了&原煤分级萃取-硅胶与凝胶柱层析分离与纯化-GC/MS或LC/MS检测-FTIR、MS、1H NMR和13C NMR波谱解析&这一煤中有机化学成分的非破坏性分离与分析的研究方法，并验证该研究方法有效可行。

Objective: To explore the feasibility of the combination of psuedo-ligand affinitive chromatography and gel chromatography in purifying RIP from bitter gourd and the cytotoxicity of the RIP.

结果： 运用硫酸铵分级沉淀、Blue Sepharose CL-6B假配基亲和层析、Sephadex-G75凝胶层析等方法提取、纯化得到了高纯度的苦瓜RIP，并且能够获得较高的得率；一定作用剂量的苦瓜RIP不仅能够抑制HL-60细胞的增殖活性，还可以诱导其发生凋亡。

Using ammonium sulfate precipitation, Blue Sepharose CL-6B psuedo-ligand affinitive chromatography and Sephadex G-75 gel chromatography, we obtained the typeⅠRIP with high purity, the feasibility of this method has been approved by SDS-PAGE results.

结果显示：1。运用硫酸铵分级沉淀、Blue Sepharose CL-6B假配基亲和层析、Sephadex-G75凝胶层析等方法提取、纯化得到了高纯度的苦瓜RIP，并且本方法提取效率较高，所获得的RIP在SDS-PAGE上呈现为单一条带。
