本工作采用无需煅烧的天然水镁石作为镁质原料制备磷酸镁水泥(MPC),主要研究了磷镁物质的量比(P/M)对MPC工作性能、力学性能、物相组成及微观形貌的影响规律。结果表明:随P/M减小,MPC浆体流动度逐渐减小,凝结时间逐渐延长,抗压强度先提高后降低。P/M为1/4时,MPC综合性能较优,此时流动度为110 mm,凝结时间为7 min,1 d和28 d抗压强度分别为20.0 MPa和43.7 MPa。微观试验结果表明,MPC水化产物为MgKPO_(4)·6H_(2)O、Ca_(10)(OH)_(2)(PO_(4))_(2)。MPC水化28 d后,水镁石未完全反应。随着P/M减小,硬化体结构密实度增加,总孔隙率减小。

With the swift development of economy, the water quality of beijing is becoming worse day by day and hampers the sustainable development obviously. In this paper, the current conditions of the municipal wastewater structure in the industrial sectors are analysed and discussed in terms of the indicators, such as direct wastewater\|discharge coefficient, complete wastewater\|discharge coefficient, direct discharge coefficient of COD and complete discharge coefficient of COD, by taking a year of 1990s as the base year. Some countermeasures are studied and the corresponding recommendations are put forward in order to improve the water environment in beijing. This provides a scientific ground for coordinating the relationship between the aquatic environment and economic growth in this city.

关键词： direct wastewater discharge coefficient (DWDC) complete wastewater discharge coefficient (CWDC) direct discharge coefficient of COD(DDC of COD) complete discharge coefficient of COD (CDC of COD)

This study was designed to obtain an understanding of the subjective well-being (SWB) status among China’s urban elderly, and to find out the major factors that could influence the status in question. Our survey was conducted of 233 urban elderly individuals, and the data was statistically examined by multiple regression analysis with the results that: 1) The SWB of China’s urban elderly was relatively high as only 4.5% of all respondents considered themselves unhappy or very unhappy; 2) Major factors that had an influence on SWB included economic resource, mobility, age and social support; and 3) Five demographic variables accounted for 18.6% of the variance in SWB, which was slightly higher than that of foreign findings. It is concluded that financial security, active participation in physical and social activities, and social support are necessary for the improvement of the SWB of the elderly.
