Study of BESⅢ MUC offline software with cosmic-ray data

Cosmic-ray data of 90 M events have been collected and used for calibration, alignment as well as detector tuning. A special tracking algorithm for the BESⅢ muon counter is developed and verified with Monte-Carlo simulation and then further confirmed with the cosmic-ray data. The obtained strip resolutions are in good agreement with the design values. A new alignment approach for the BESⅢ muon counter is confirmed with the cosmic-ray data and proposed to be used in future analysis of experimental data.     

Application of Nanogold Probe Coupled with Silver Enhancement in Rapid cTnI Colorimetric Immunoassay

Cardiac troponin I (cTnI) in the serum of patients has been established as a principal biochemical marker of myocardial damage1-4. Fast detection of cTnI will be helpful for the diagnosis of acute myocardial infarction (AMI), the identification of myocardial injury (MI) and the stratification of cardiac risk. A number of serological tests have been developed for the detection of cTnI. As known, among many methods, enzyme-linked immunosorbent assay (ELISA) and radioimmunoassay (RIA) wer…     

等点时Cu（Ⅱ）与HSA与BSA结合的研究

用平衡透析法研究了等电点时Ｃｕ（Ⅱ）与人血清白蛋白（ＨＳＡ）或牛血清白蛋白的相互作用，Ｓｃａｔｃｈａｒｄ图分析表明，ＨＳＡ和ＢＳＡ对Ｃｕ（Ⅱ）各有１个强结合部位，它可能位于白蛋白分子的Ｎ－端三肽段上，为全面反映Ｃｕ（Ⅱ）与ＨＳＡ或ＢＳＡ的结合情况，用非线性最小二乘法拟合Ｂｊｅｒｒｕｍ方程，首次报道了等电点时Ｃｕ（Ⅱ）－ＨＳＡ和Ｃｕ（Ⅱ）－ＢＳＡ体系的逐级稳定常数值，其Ｋ１的数量级为１０＾４．Ｈｉｌ     

Decay vertex reconstruction and 3-dimensional lifetime determination at BESⅢ

This paper focuses mainly on the vertex reconstruction of resonance particles with a relatively long lifetime such as KSO, A, as well as on lifetime measurements using a 3-dimensional fit. The kinematic constraints between the production and decay vertices and the decay vertex fitting algorithm based on the least squares method are both presented. Reconstruction efficiencies including experimental resolutions are discussed. The results and systematic errors are calculated based on a Monte Carlo simulation.     

非均匀加速结构腔间耦合系数模拟计算

电子直线加速器的聚束段对于会聚入射电子相位,提高电子直线加速器出射束流性能起着至为关键的作用. 而准确计算聚束段腔间耦合系数又是设计聚束段耦合孔几何结构的关键. 本文利用电磁场计算软件MAFIA的特征值计算模块E模块, 分别计算出单腔频率, 双腔腔链的两个本征频率,从而得到聚束段腔间耦合系数. 采用该方法,可以设计聚束段腔间耦合孔的几何参数. 与实验结果的对照表明, 这是一种非常有效的非均匀加速结构腔间耦合孔设计方法.

π形山脉主山脊线风速加速效应研究

为研究真实地形的加速效应，提取真实地形的几何特征建立理想简化地形，提出一种π形山脉模型.采用CFD数值模拟研究顺子山脉风向下子山脉间距、长度及坡度对主山脊线加速效应的影响，结合地形特征比较π形山脉与三维余弦山脉的主山脊线加速比差异，在后者基础上获得π形山脉主山脊线特征点的风速加速比简化计算公式，并通过一处真实π形山脉加以验证.结果表明：π形山脉主山脊线中点的加速比受子山脉间距、长度影响较大，而山脊线交点的加速比受子山脉长度、坡度影响较大；与三维余弦山脉相比，π形山脉主山脊线加速比在山脊线端部相同，但整体偏小，尤其受子山脉遮挡的部分显著偏小，超过离地70 m高度后差异基本消失；通过与真实π形山脉的风场比较，发现简化地形和简化计算公式能较好反映真实地形主山脊线特征点的加速效应.
