Saikosaponins from roots of Bupleurum scorzonerifolium

Saikosaponin u and saikosaponin v, were isolated from the roots of Bupleurum scorzonerifolium and these saponins were identified as 3-O-[beta-D-glucopyranosyl-(1-->2)-beta-D-glucopyranosyl- (1-->3)-beta-D-fucopyranosyl]-3 beta,16 alpha,23,28-tetrahydroxy-olean- 11,13(18)-dien-30-oic acid-30-O-[pentito(1-->1)-beta-D-glucopyranosyl-(6-->)] ester and 3-O-[beta-D-glucopyranosyl-(1-->3)-beta-D-fucopyranosyl]-3 beta,16 alpha,23,28-tetrahydroxy-olean-11,13(18)-dien-30-oic acid-30-O-[pentito(1-->1)-beta-D-glucopyranosyl(6-->)] ester, respectively.     

特低渗超高压深层边水油藏的开发方式

对典型的特低压深层边水油藏文８８块的开发方式进行了研究,研究表明：油藏弹性溶解气驱和边水驱量较充足,油藏差,原油粘度低,流度较大,难以实现注水开发,而利用天然能量开发地质,工艺经济上皆可行。并就此研究了配套的开发技术政策,作出方案部署,经实施,油藏开发水平提高,经济效益显著。     

HDK-96道水下接收系统简介

为适应海洋地震勘探发展的需要,海洋局地调处已研制成功HDK-96道水下接收系统。该系统分若干段装在壁厚3毫米、外径为51毫米的聚氯乙烯塑料软管内,作业时管内充轻腊油(液态石腊),以保证系统的比重略大于海水比重。各段之间是用250芯密封插件联接,插件承受拉力为4-5吨。作业拖放时总长度约3000米,用定深器使其保持在水下一定深度(如图1)。     

改良型湿壁塔液膜传质特性与端末效应的研究

VIS absorption spectrophotometry of disperse dyes

In the investigations of the dyeing processes, the low solubility of disperse dyes in water represents a practical problem for the determination of dye concentration in dyebaths and waste waters. Therefore the use of an organic solvent which, dissolves disperse dyes, is recommended in visible spectrophotometry of disperse dyes. Three organic solvents (ethanol, N,N-dimethylformamide, acetone) and two disperse dyes, the disazo dye C.I. Disperse Orange 29 and the anthraquinone dye C.I. Disperse Blue 56, were used for spectroscopic analysis in this present work. The absorbance of aqueous dye dispersions and various organic solvent dye solutions was measured to evaluate the effect of the solvent on the shape and intensity of the absorption spectra and on the wavelength shift of maximum absorption. The validity of Beer–Lambert’s law in each system was ascertained. A suggestion is made how VIS absorption spectrophotometry can be used to determine the dye concentration in disperse dyebaths. The addition of organic solvent to the dyebath leads to dye dissolution, and the Beer-Lambert’s law is then fulfilled. The optimum ratio between the dyebath dispersion and the organic solvents for the dyes investigated is also determined.
