多组样本下GL—统计量的渐近性质

本文主要讨论多组样本下GL－统计量的渐近分布,这里我们使用了Gateaut微分逼近方法,在多组i.i.d.样本下,给出了GL－统计量的渐近正态分布的一组条件,从而拓广了i.i.d样本下GL－统计量的渐近正态分布的性质[1]。

基于不同波长的光对葡萄糖溶液旋光色散的研究

通过不同波长的光源照射葡萄糖水溶液,观察到旋光现象,并测出了不同波长所对应的旋光度,从而计算出它们的旋光率。通过分析测量数据得,在一定温度下葡萄糖溶液旋光率与波长具有对应的函数关系,证实了旋光率与照射光源波长倒数的平方成正比。     

Feasibility study on cross-section measurement of Y（1S） →μ^＋μ- by using early CMS data

One of the first physics results that CMS will hopefully obtain will be the analysis of heavy quarkonium productions, including the Υ cross-section measurement. Since the Υ production cross-section from p-p collisions is expected to be relatively large, the analysis should be viable with rather small datasets which will be available soon after the start-up of the LHC. This paper describes the methods and plans for measuring the differential cross-section of Y（1S） →μ^＋μ- production, by using data to be collected from the CMS detector in the first LHC run. In this study, about 80 thousand Υ are reconstructed corresponding to an integrated luminosity of 6.4 pb^-1 in 10 TeV proton-proton collisions by using Monte Carlo data. The precision of this measurement is estimated to be about 16%, which is limited by the systematic errors.     

D-葡萄糖溶液变旋规律的研究

测定了新配制的不同浓度的葡萄糖溶液的比旋光度,分析了溶液的变旋现象,进而研究旋光度变化与时间之间的规律,结果显示溶液比旋光度随时间呈指数变化,并最终达到稳定.
