薄片生产阻燃式反吹风储料器的改进设计

由于阻燃式反吹风料仓内部风力输送系统,在使用过程中容易造成风压过大,导致气流中夹带的烟粉和烟粉末在超标压力下大量外扬,通过采用增设负压装置平衡系统内气流压力的方案,有效改善了除尘效果。另外,用带分度盘的皮带传动替代了复杂的行星摆线针轮减速器,节省了投入,且操作维护简便。

Sectoral Comovement,Monetary Policy Shocks,and Input–Output Structure

The comovement of output across the sector producing nondurables (i.e., nondurable goods and services) and the sector producing durables is well established in the monetary business cycle literature. However, standard sticky‐price models that incorporate sectoral heterogeneity in price stickiness (i.e., sticky nondurables prices and flexible durables prices) cannot generate this feature. We argue that an input–output (I–O) structure provides a solution to this problem. Here, we develop a two‐sector model with an I–O structure, which is calibrated to the U.S. economy. In the model, each sector’s output affects those of the others by acting as an intermediate input. This connection between the sectors provides a channel through which sectoral comovement is induced.

地震作用下框架填充墙结构的有限元分析

框架填充墙结构在地震作用中受到的破坏最为严重,亟需提出针对该类结构合理有效的分析和计算模型。文章中,对一幢纵横向均为三跨的五层框架填充墙结构采用SAP2000结构分析软件进行有限元分析,先后按实际填充墙布置建模、以及按照等效斜撑布置建模,对比规范规定的采用0.7的周期折减系数的分析方法。验证了规范中所采用的周期折减系数是严重低估填充墙对框架结构刚度的影响的,在设计中将导致严重安全隐患。并同时提出了更为简便、且满足工程要求的等效斜撑截面面积计算方法,建议在框架填充墙结构的相关分析和设计中采用此方法。     

Sarma法中非饱和计算功能的实现探讨及应用评价

在考虑非饱和基质吸力条件下,基于Bishop单值有效应力非饱和土强度理论和Fredlund双应力变量非饱和土强度理论,探讨在传统的Sarma法中实现非饱和边坡的稳定性分析的思路和方法,开发了可考虑基质吸力的Sarma条分法的相关程序,并针对一个非饱和土滑坡进行稳定性分析,结果表明:两种改进的Sarma法在分析非饱和土边坡时基质吸力影响的考虑方式不同,这种差异会对计算结果产生一定影响,但误差是有限的。

精细构造解释技术在吉林油田木101井区的应用

吉林油田从勘探转入开发,原有三维地震解释方法已经不能满足开发阶段布井的精度要求,需要进行地震资料的精细标定与精细构造解释。选择和应用了多井综合标定和合成记录综合标定、三维可视化数据校正等诸多国内外分析技术,一方面提高了地震解释工作效率,另一方面保证了时深转换及构造成图的精度,形成了一套满足开发阶段精度要求的解释和成图的技术方法。     

Intelligent tools and techniques for modern management

In order to make decisions all companies need information. As a rule, all the informatics systems of a company contain a multitude of data and turn these data into information that has to be analyzed in order to make decisions. It is a slow process. The solution of this drawback is given by Business Intelligence （BI） applications that can help companies increase income or diminish costs by offering the executive management appropriate information on the basis of which quick and efficient decisions can be taken.
The main purpose of the paper is to prove the necessity that BI tools should be used by the modem manager. Managers are aware of that by putting into practice the BI solutions, opportunities of getting control over the business process and methods are improved and better, timely analysis functions of the performance parameters can be obtained.
