在大学生中进行艾滋病健康教育的重要性

为了解大学生掌握艾滋病知识的现状,使学校为进行艾滋病健康教育提供科学依据,从而确定在大学生中进行艾滋病教育的重要性,采用自行设计的艾滋病相关知识问卷,采取整群随机抽样方法,选择2005年入学新生进行无记名问卷调查.调查问卷主要内容包括艾滋病相关知识、态度和行为.结果显示,大学生对艾滋病基础知识有了一定的了解,但对艾滋病知识掌握不够全面,尤其是对艾滋病病原体等专业性问题的知晓率较低.对于一些非传播艾滋病途径错误认识率较高,大多数学生对艾滋病存在着恐惧心理,有一部分学生认为艾滋病离自己还远.因此,对大学生进行艾滋病知识教育非常必要.在学校开展艾滋病教育有着极其重要的战略意义.     

印度数学奇才拉马努金

自从16世纪以来，剑桥大学一直是英国的最高学府，在她拥有的种种优良学术传统中，有两点至关重要，那便是精英意识和团队精神。前者的典范是卢卡斯数学教授和卡文迪什实验物理学教授职位的设立和聘请，后者则表现为这所大学的大门始终向全世界的英才敞开。1912年，23岁的奥地利工科大学生维特根斯坦应邀来到了剑桥，与那个时代最伟大的两位哲学大师罗素和摩尔密切共事。两年以后，来自印度南方马德拉斯港务局的小职员拉马努金也被请到了剑桥．与两位正处于事业颠峰的数学巨匠哈代和李特尔伍德开始了天作之合。不到四年。拉马努金也和他的两位同事一样，名字后面有了一个记号F．R.S.，即英国皇家学会会员，那年他刚满30岁。

研究了测定熟料中二次游离氧化钙的条件。结果表明 :只要增大分析试样的细度 ,保证足够长的萃取时间 ,用甘油 乙醇法和乙二醇 乙醇法都能测定出熟料中的二次f CaO ,乙二醇 乙醇比甘油 乙醇萃取速度快。     

水稻籼粳杂种多倍体的研究

以秋水仙碱诱导的水稻籼粳杂多倍体植株中，部分植株的体细胞呈现具有整倍体和非整倍体染色体数细胞嵌合现象，其中四倍体细胞最高可占35．3％，其余均为染色体数低于48条的各种细胞，与二倍体植株相比，这些植株的叶表皮气孔增大，气孔数减少，花粉粒直径增大都是十分显的，与多倍体植株无明显区别，并对这类植株根尖体细胞中存在具各种染色体数目细胞嵌合现象可能的原因进行了分析。     

Microelement analysis of source of raw materials of terracotta warriors and horses of Qin’s Mausoleum in pits No. 1 and No. 2

In order to search for sources of the raw material of the Qin’s terracotta warriors and horses, we selected 20 samples of pottery warriors and pottery horses of the Qin’s Mausoleum from pit No. 1, 19 samples of pottery warriors and brick from pit No. 2, 20 samples of clays near the Qin’s Mausoleum and 2 samples of Yaozhou porcelain bodies. The 32 kinds of element content of each sample were measured by neutron activation analysis (NAA). These data were analyzed by fuzzy cluster analysis, the trend cluster analysis diagram was obtained. The results showed that samples of terracotta warriors and horses from pits No.1 and No. 2 were closely related to the loam layer near Qin’s Mausoleum, but their relations with the loess layers were not so close, and they were out of all relation to Yaozhou porcelain bodies. Thus, it could be deduced that the Li Mountain clay may be considered as the original place of the raw materials of the terracotta warriors and horses, the kiln sites might be located nearby the Qin’s Mausoleum.     

Modeling studies on the changes of the Subtropical High over the Western Pacific during the last 100 years

Intensity index series of Subtropical High over the Western Pacific was constructed according to modeling results by using of CCM3.6 atmospheric model with climatologically SST forcing for 30 years, and with observed SST forcing from 1900 to 2000. The index series constructed by modeling closely correlated to the observations for 1951-1999 (c.c. 0.72) and to the statistically reconstructed one for 1900-1950 (c.c. 0.51). The index series for 1900-1999 showed significant 80 a and 40 a periodicity. A minimum of persistence in seasonal variations of the index occurred in Autumn, which was called "Autumn Barrier". It may relate to the "Spring Barrier", found in the seasonal variations of SST over the Eastern Equatorial Pacific. The increasing trend shown in the index series for the 20th century may associate with the global warming caused by enhancement of greenhouse effect.
