水闸闸室化算梯形横截面上不平衡剪力的分配计算

当地弹性地基梁法计算非岩石地基的水闸底板应力时，首先要求解出不平衡剪力，当闸墩截面选择梯形时（主要是边墩），常用方法是作图法，这既有误差又繁琐。所以就此推导出一个公式，可直接求解平衡剪力。

Regulation Fair Disclosure and Earnings Information: Market, Analyst, and Corporate Responses

With the adoption of Regulation Fair Disclosure (Reg FD), market behavior around earnings releases displays no significant change in return volatility (after controlling for decimalization of stock trading) but significant increases in trading volume due to difference in opinion. Analyst forecast dispersion increases, and increases in other measures of disagreement and difference of opinion suggest greater difficulty in forming forecasts beyond the current quarter. Corporations increase the quantity of voluntary disclosures, but only for current quarter earnings. Thus, Reg FD seems to increase the quantity of information available to the public while imposing greater demands on investment professionals.     

混凝土芯砂石桩复合地基加固堤防软基试验研究

介绍了一种新型的地基处理方法——混凝土芯砂石桩复合地基法及其在水利防洪堤软基加固工程中的应用情况。通过现场原位观测和试验,研究了混凝土芯砂石桩复合地基固结变形、孔压消散、桩土应力分担及承载力特性,结果表明混凝土芯砂石桩强度高,排水固结能力强,能迅速提高桩间土强度和承载力,应用于水利堤防工程既能控制堤防深厚软基的工后沉降,又能提高堤防边坡的稳定性,推广应用前景良好。

The impact of time duration between trades on the price of treasury note futures contracts

Recent research in finance has indicated that the institutional structure in which financial asset prices are determined can have a nontrivial impact on pricing. This report examines transaction level data for Treasury Note futures contracts traded at the Chicago Board of Trade (CBOT) to identify institutional, or market microstructure, impacts on the pricing of these contracts. Relatively few articles have conducted empirical research on the microstructure of U.S. futures trading due to the limited availability of comprehensive transaction level data from the futures exchanges. This report uses the CBOT's Computerized Trade Reconstruction database, a comprehensive transaction level dataset, to identify the price impact of the time duration between trades in a manner analogous to that of A. Dufour and R. F. Engle (2000). Unique differences from prior research include the application to futures contracts with their relative higher frequency of trading, as well as the investigation of the price impact of the number of active traders present on the trading floor and the trading volume. Subsequent price and sign of trade significantly relate to the time duration between trades, the number of floor brokers, and the trading volume. © 2004 Wiley Periodicals, Inc. Jrl.
