两种测量理论(CTT和IRT)的分析与比较

针对两种测量理论(CTT和IRT)进行了分析和比较，提出在试题参数确定上的做法可以根据具体情况，以IRT在试题参数测试的不变性为基础，充分利用CTT的优点，抓住IRT与CTT的统计结果之间存在的相关性．取两者之所长，将两者有机地融合，实现客观评价教育质量的目的。     

41条牦牛CDS序列的密码子偏好性分析

密码子简并性特征造成了不同物种密码子使用偏好性不同．在对牦牛功能基因组学研究的基础上，利用EMBOSS中的CUSP程序、SMS2中的Codon Usage程序和软件CodonW对牦牛功能基因的41条CDS序列进行了密码子偏好性的分析，并与人、普通牛、猪等物种进行了比较基因组学研究．结果显示：TTC、TTG、CTC、CTG、ATT、GGA、GGG等27个密码子为牦牛的偏好性密码子．研究结果为以后进一步开展牦牛新基因的发现、功能基因表达调控研究，蛋白质结构和功能的预测以、与其他牛种的比较基因组学研究以及牦牛分子标记育种等工作，提供了理论基础．

Lightning activity on the central Tibetan Plateau and its response to convective available potential energy

Lightning flash activities on the central Tibetan Plateau have been studied by using the satellite-based Lightning Imaging Sensor(LIS)database from January 1998 to July 2002.The lightning activity shows a clear diurnal variation on the central Plateau.The peak lightning activity appears at about 17:00 which is 3 h earlier than that in Jingxhou,Hubei in the same latitude belt nearby,indicating that the lightning activity is a sensitive indicator of solar heating on the Plateau.The lightning discharge is weaker on the Plateau than Jingzhou.Hubei and other low-altitude continental regions because of the lower convective available potential energy(CAPE)on the Plateau.The CAPE on the Plateau is 12 times lower than that in Jingzhou,Hubei,and 20 times lower than that in the sea-level region,such as Guangzhou and Florida.However,the sensitivity of lightning activity to CAPE changes on the Plateau is up to 30 times more sensitive than other prominent low-altitude regions.     

C－isotope composition and significance of the Sinian on the Tarim plate

102 samples of limestones,mudrocks shales and tillites from the Sinian in Kuluketage have been analyzed ,Four formations in the Sinian belong to glacial deposits in which the differences in δ^13C are distinct (-14.7‰- 4.2‰),Distinctly negative δ^13C excursions for three times support the viwe of three glacial deposits in this area suggested by previous authors,except for the durations of them ,δ^13C values are generally positive in the Beiyixi Formation of lower part of the Lower Sinian ,representing probably the rock records of a continental rift related to break-up of the Rodinian supercontinent,There are three times of distinct excursions of δ^13C curve in all strata,The first one is from positive values at the bottom to about -5‰ at the top of the Beiyixi Formation ,The second one,from 0‰-3‰ in the Arletonggou Formation of upper part of the Lower Sinian to -3.4‰---14.4‰ in the Teruiaiken Formation.The third one,from positive values in the Zhamoketi Formation of lower part of the Upper Sinian to negative values in glacial varves at the top of the Hankeerqiaoke Formation.
