实验结果表明：在相同条件下，异丙醇的分相能力大于乙醇；温度对磷酸氢二钾+乙醇／异丙醇+水体系分相能力的影响很小；磷酸氢二钾水溶液的pH值对体系的分相能力影响较大，当pH值较小时，体系不能形成两相，当pH值＞6时，随着pH值的升高，分相能力逐渐增强；外加少量无机盐NaCl，对体系的分相能力影响不大。

In this paper, magnetorheological fluids and it's rheological behavior were introduced. And the principle of the disc-shaped magnetorheological fan clutch was investigated theoretically. The Bingham model was used to characterize the constitutive behavior of MR fluids subject to an external magnetic field. Based on Bingham model the expressions of the torque and the output rotational speed within the clutch is derived to provide the theoretical foundation in the discal design of the clutch. Then the calculations of the radius of the disc, the thickness and volume of MR fluids within the MRF clutch are yielded. Finally, the sketch of the clutch was designed.

Our other primary insurers delivered their usual fine results last year. These operations, run by Rod Eldred, John Kizer, Tom Nerney, Michael Stearns, Don Towle and Don Wurster had combined premium volume of $579 million, up 40% over 2000. Their float increased 14.5% to $685 million, and they recorded an underwriting profit of $30 million. In aggregate, these companies are one of the finest insurance operations in the country, and their 2002 prospects look excellent.

我们其它初级的保险公司去年的表现依旧出色， Rod，由 John， Don， Tom， Michael 等人带领的各家保险事业，总计贡献了 5.79 亿美元的保费收入，较 2000 年成长了四成，浮存金则增加 14.5%成为 6.85 亿美元，外加 3，000 万美元的承保利益，总的来说，这些公司堪称全美最好的保险公司之一，展望 2002 年他们的前景依然可期。

There are some midst matters in wastewater, for removal of these matters the electrolyze time should exceed 30 min. The experimental results show that the bipolar packed bed cell has best treatment efficiency of phenol wastewater under condition that voltage is 10V, electrolyses time is 30 min, and velocity of flow is 1.03 cm/min.Basic on the study on treating of phenol wastewater, this paper carry on a research on treating of circuitry board film wastewater by bipolar packed bed cell.

本文在以上处理苯酚废水研究的基础上，论文研究了BPBC处理两种不同浓度得脱膜废水，试验结果表明，对于浓度较高的酸化气浮-光酚顿的出水，在外加氧化剂双氧水后，最佳处理工艺：槽电压8V，实际电解时间60min，双氧水的投加量为1倍理论药量，pH值为3，COD的去除率达到60%；在酸化气浮过程采用酸铜废液调节pH值将会降低COD的去除率。

The interfacial tension between ABEPS solution and crude oil had been investigated. It was shown that ABEPS not only displayed outstanding salt resistance, but also good hard-water endurability, furthermore ultra low interfacial tension could be achieved without alkaline but proper amount NaCl in the water-crude oil system, which proved its excellent interfacial performance and better application prospects.

本论文还通过对ABEPS水溶液与原油之间的界面张力测定，发现ABEPS不仅具有出众的耐盐性能，而且具有良好的抗钙镁性能，合适的盐浓度下，表面活性剂水溶液与胜利原油之间可以在没有外加碱的情况下形成超低界面张力，说明这类表面活性剂具有良好的界面活性和潜在的应用前景。

The purpose of this thesis is to explore other yet undiscovered contrast origins and unused contrast agents of third-harmonic-generation inside biological tissues, and apply to the preliminary studies of medicine based on a nonlinear laser scanning microscopy system using a femtosecond Cr:forsterite laser centered at 1230-nm.

The results indicate that the high efficiency and stable performance of shortcut nitrogen removal in MBR-PBBR process is attributed to the predominance of functional microbiology Nitrosomonas eutropha during the period of operation,which occupies over 54%of total bacteria.However,large amount of organic carbon can destroy the predominance of N.eutropha,whose proportion decreased to 31%at TOC/N=0.3.The diversity of microbial community in MBR increases along with operating time.

结果发现，生物强化的MBR-PBBR工艺能实现相对稳定和高效的捷径生物脱氮，主要归功于MBR中的功能微生物Nitrosomonas eutropha在运行过程中始终保持优势地位，占全菌数的比例大于54%；然而，当外加有机碳源较高(TOC/N≥0.2)时，可动摇氨氧化菌的优势地位，N.europha占全菌数的比例在TOC/N=0.3时下降至31%。
