等渗、高渗、低渗溶液与人体健康

人体内充满了溶液,如细胞液、组织间液、血液、各种腺体的分泌液等.不同浓度的溶液具有不同的渗透压.在正常情况下,人体各处的渗透压是相对稳定的,如37℃时血浆渗透压为770kpa .渗透压的相对稳定,才能使人体各种组织细胞形态正常,内环境才能保持稳定,人体才能保持健康.若人体不同部位的渗透压发生变化,形成高渗、低渗溶液,将会对人体健康产生影响.

改进型渗压仪的研制与实验室应用

为了提高渗透试验的效率和精度,发挥实验教学中学生的主观能动性,设计出一款改进型渗压仪。该仪器基于岩土工程实验室常用QY1-3型渗压仪,采用GDS控制器加载渗透压力,由JM3811静态应变测试系统采集试样的轴向变形,通过计算机模块控制试验、整理数据。通过与普通渗压仪对某地软黏土渗透性的对比,采用3种先期固结压力和两种渗透压力加载方式,验证改进型仪器的性能。实验结果显示:软黏土的渗透系数随先期固结压力的增大而减小,受渗透压力的影响很小。改进型渗压仪的操作简便,结果可靠、精度高,测量时间短,功能多样化,不但能满足科研和教学需要,同时提高了测试效率和学生动手操作能力。

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.
