干滑动摩擦磨损试验表明：复合材料的耐摩擦性比纯基体合金明显提高，施加电磁搅拌后复合材料的耐摩擦性进一步提高，特别是在较大载荷下的耐摩擦性大幅提高，从轻微磨损到急剧磨损的临界转变载荷由58.8N提高到78.8N。

Based on the analysis of Laoshan District, the research was carried on including water environment capacity, water allocation and forewarning evaluation. Hydraulics, System Dynamics and analytic hierarchy process are applied in the research. The main contents and conclusions are as following:1. With economic development, urbanization and continuous improvement of people\'s living standards, the demand of water resources in Laoshan District will continue to increase dramatically.

本文在分析青岛市崂山区水资源利用现状的基础上，运用水力学、系统动力学和层次分析法，对区域水环境容量、水资源优化配置和水资源复合系统安全预警进行了系统的研究，主要得到以下结论：1、随着经济建设、城市化的发展和人民生活水平的不断提高，崂山区水资源需求量正在并将继续急剧增加，且由于区域水资源时空分布不均衡，新水源开发、客水调入难度大，部分地区已出现水资源紧缺状况。

The outbreak of global banking crisis, bring about the quick atrophy of overseas demand, this gives a lot of home the company, the business that is engaged in exporting export especially was brought live austerely challenge.

In this paper the reason of rapid increase of single phase short circuit current in 500 kV substation is analyzed. Through the calculation it is proved that neutral grounding by small reactance is an effective measure to reduce the single phase short circuit current, and the calculation method of the zero\|sequence reactance after autotransformer neutral grounding by small reactance being applied is expounded.

文中研究了500kV变电站单相短路电流急剧增长的原因，计算了变压器中性点经小电抗接地对限制单相短路电流的作用，论证了经小电抗接地是限制单相短路电流的有效措施之一，并阐述了500kV自耦变压器中性点经小电抗接地后，其等值零序电抗的计算方法，可供工程参考。

The rates of being overweight and obese in the baby boomer age range is dramatic compared with residents over 75 years of age.

In seven out of 9,and 6 out of 13 hens treated with chlorpromazine or cyproheptadine terminated broodiness following drug treatment,blood PRL levels all decreased from high levels on day 2 of broodiness to levels below 20 ng／ml on day 4 and maintained at low levels to day 19 after onset of broodiness.

试验2：7只就巢鸡在就巢的第2、4、9、14和19 d血浆PRL水平维持在200～400 ng／ml之间；9只氯丙嗪处理后终止就巢的7只鸡以及13只赛更啶处理后终止就巢的6只鸡，血浆PRL由就巢第2 d与对照组类似的高水平急剧下降到第4 d小于20 ng／ml，并至第19 d一直处于较低水平。

Using the aforementioned experimental methods,the author has performedcareful study on the thermoanalytical characteristic of nanocrystalline brookite-basedTiO2,and found that on the DTA curve there exists a small irreversible endothermicpeak,which is related to the dramatic structural phasetransformation from brookite to anatase then to rutile.

利用上述实验手段，作者首次对板钛矿基(brookite-based)纳米TiO2的热分析特性进行了较系统、深入的研究，发现在DTA曲线上存在一较小的不可逆、无失重吸热峰，对应于从板钛矿经锐钛矿到金红石的急剧转变。

Environmental problems are more and more concerned and both environmental protection and sustainable development are paid close attention to all over the world.
