商纣王的年代学研究——夏商周断代探索之二

商王征伐人方在十祀（１０年），联系３件其铜，证明帝辛（即商纣）十祀在公元前１１５４年或１０９２年。构建帝辛历谱的初步框架。     

中国元明时期交食推步的比较研究

中国元，明两朝凡三百六十余年，历法唯《授时》、《大统》。本指出两历气朔和交食之推步差异以及根据历术术给出推步法与是时历官所用算法之差异；同时取历官实用算法就元“授时历议”和明“历法沿革”中的交食记录进行了得核；在此基础上对正史所载的３１次古日全食记录的古今推步结果进行了分析、比较。     

State-space models for predicting IBNR reserve in row-wise ordered runoff triangles: Calendar year IBNR reserves & tail effects

The issue of modeling and forecasting IBNR (incurred but not reported) actuarial reserve under Kalman filter techniques and extensions, using data arranged in a runoff triangle, is a frequent theme in the literature. One quite recent approach is to order the runoff triangle under a row-wise fashion and use linear state-space models for the resulting data set. To allow new possibilities for short-term IBNR reserves as well as to mitigate insolvency risk, in this paper we extend such a state-space method by: (i) a calendar year IBNR reserve prediction; and (ii) a tail effect for the row-wise ordered triangle. The extension is implemented with a real runoff triangle and compared with some traditional IBNR predictors. Empirical results indicate that the approach of this paper outperforms the competing methods in terms of out-of-sample comparisons and gives more conservative IBNR reserves than the original state-space method.     

边冈逐次分段抛物内插法

推广了中国唐代的历算家边冈在其崇玄历中发明的一种逐次分段抛物内插法。通过计算新的插值点上的被插函数与插值函数之差，判断分段效果的好坏，以此确定分段是否仍需进行下去，若是，则此差值便可给出下一轮分段抛物插值函数。并对其收敛性与插值余项的精度估计进行了讨论。     

日历中一种周期现象的解析

指出日历中的国庆日与中秋节重合这种现象发生的周期性.从公历和农历的历法依据——回归年和朔望月出发,利用辗转相除法以及连分数等数学方法对农历的置闰月规律加以推演,进而得出两种历法运行的会合周期.同时对其会合周期的差异性加以分析.

全球时空系统问题剖析与调整建议

在全球时空系统中,建议改用0°和180°经线划分东、西半球,与南北半球划分标准一致;建议采用同地球自转运动规律相契合,按自然顺序将全球划分为1~24个完整时区的简明方案;建议采用180°经线为日界线,取消日界线避开陆地的3处曲折,保持日界线的稳定;建议改革现行公历,实行好记好用的新历法,采用大(单)小(双)月有序交叉,大小月个数相等,2月平年为29 d,闰年为30 d的设置.

略论杜预的科学技术工作

论述了3世纪时中国重要学者杜预(222—284)在科学技术方面的工作。全文分为生平事迹和军事谋略、对农业经济的见解、对历法的研究、对地理学的研究、在技术方面的研究工作等5个小题进行论述。杜预具有非凡的思维能力，是当时科学家和思想家群体(如裴秀、刘徽、王叔和、杨泉、张华等)中的重要一员。     

Empirical Analysis of Seasonality Anomalies in Chinese Stock Market Based on Rolling Sample Tests

The paper uses rolling sample tests to investigate calendar effect in Chinese stock market, the method is very suitable for emerging market. We utilize GARCH （1,1）- GED model to identify the time varying nature of calendar effect. Friday effect existed with low volatility at the early stage, but it seems to disappear since 1997, and positive Tuesday effect began to appear then. There is small firm January effect with high volatility.
