两汉儒学独尊为什么会养成一个士大夫阶层？

材料一：2010年1月～2011年1月我国居民消费价格指数同比变化情况

研究发光物体的光谱通常需要三棱镜，如图所示是截面为等边三角形ABC的三棱镜，一束光从AB边的P点射入棱镜，当入射角i=60°时，进入棱镜的折射光线与BC平行。求：

①光在棱镜中的传播速度v(光在真空中传播速度c=3×10⁸m/s)

②入射光经过棱镜两次折射后偏转的角度θ。

Like a growing number of young women in Vietnam’s northern part city of Haiphong, Pham Thi Hue was infected with HIV by her husband, one of the town’s many drug users. But instead of being shamed into silence, as Vietnamese with HIV and AIDS are, the 25-year-old tailor and mother of one went public, appearing on television and at conferences. Her business suffered and her neighbors insulted (辱骂)her, but Hue has now become the public face of Mothers and Wives, an HIV/ AIDS support group established in Haiphong by a Norwegian nongovernmental organization and her neighborhood’s People’s Committee. Last year, she founded a smaller group named after a local flower. People who need advice on treatment or help preparing bodies for burial can dial a hot line and get assistance from able and sympathetic(同情的)HIV victims. “We gather to support each other,” Hue says. “When we are sick, what we need most is encouragement and comfort from people who understand our situation and are willing to share our happiness, as well as our sadness.”

On a hot and damp night last month, Hue welcomed into her small home a very thin woman, also a tailor, who was HIV positive. The woman tearfully told Hue that she had not told anyone about her condition, fearing that she would lose customers and that her daughter would be insulted at school. Hue became the wise elder, offering medical and personal advice.
