针对钢渣体积稳定性差、钢渣-沥青混合料道路过早开裂的问题,采用二氧化硅胶体溶液对钢渣进行浸泡改性处理,通过力学性能测试、扫描电子显微镜（scanning electron microscope,SEM）检测、路用性能测试等方法研究了改性钢渣的物理力学性能、改性钢渣-沥青混合料的性能和钢渣的改性机理,并引入灰靶理论决策方法,综合改性钢渣-沥青混合料的各项性能指标,确定钢渣的最佳改性方案。结果表明：钢渣改性后,物理力学性能明显提高;钢渣的改性浓度越大,沥青混合料的高温性能越佳;延长钢渣的改性时间,沥青混合料的低温抗裂性能提高;且钢渣改性之后,沥青混合料的水稳定性能显著提高。基于灰靶决策理论,最终确定钢渣的最佳改性方案是在改性浓度（溶液质量分数）为3%的溶液下浸泡24 h。

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.

胡主席在印度,我却在中国

Today, Sunday morning, I sit thinking and typing at my computer. My thoughts are in my homeland, India and my body is in China. The body is here and mind there for a good reason. Mr. Hu is president and I am resident and both are in each other's countries (what a difference the absence of one small letter makes!). Mr. Hu will return in a few days and I will stay on longer.
