<正>一、建立健全煤矿机电设备维修制度在煤矿企业中,机电设备管理涉及面广,工作量大,必须有一套健全的机电管理制度。首先要建立以一把手为核心的设备管理目标化组织机构。确立目标,落实责任,组织开展工作。其次以质量标准化为基础,建立一整套严密、科学的管理制度和管理办法。实现目标化、程序化、规范化管理,以保证设备维护、检修、保养、点检等落实到人头,做到台台设备有人管,有人抓,不留死角。

In this paper,the wave velocity ratio in the Puyang and its surrounding area(35.1°～36.0°N,115.1°～115.7°E) is calculated and tested with T-test. The results show that the Vp/Vs ratio of this area calculated on basis of 41 ML≥2.6 earthquakes is normal in the period of 2001-2008.The focal depth of ML≥3 earthquakes occurred in Heze-Puyang and its surrounding area(35.1°～36.0°N,115.1°～115.7°E) from 1970 to 2008 is analyzed.The result indicates that focal depth(average of 19km) of the earthquakes occurred before Heze 1983 Ms5.9 earthquake are deeper than that(average of 13 km) of earthquakes occurred after the Heze 1983 Ms5.9 earthquake.

Using travel-time equation of direct wave,the average velocity of direct P-wave and direct S-wave(ν-p-=6.13 km/s,ν-s-=3.52 km/s) in Juxian-Tancheng area are calculated based on 23 Multiple screened earthquakes and 130 sets of high-precision seismic parameters.Then,the crustal thickness(HP11,HS11) of the study area are calculated using the reflection P-wave,reflection S-wave.The results indicate that the average crustal thickness in Junan-Tancheng area is about 34.8 km.

Article from the active fault study the progress of ideas and starting, by means of geophysical exploration, seismic geology, engineering geology, such as theory and method of the Wangmushan carried out a detailed fault studies. That the seismic reflection wave exploration method for faults with high accuracy, the Wangmushan of the fault to determine the spatial distribution, movement in nature, the activities of the times, made some valuable results. Wangmushan of the fault detection and identification of active seismic safety evaluation for the work of an important theoretical value, the earthquake resistance of buildings of great significance to security.

作为二十一世纪中国最大、最现代化的钢铁联合企业,宝钢在行业内所取得的成绩备受瞩目.宝钢建厂三十周年之际,又连续第三年获得了"财富"杂志评选的"全球最受赞赏公司"称号,并且大幅提升至全球五百强企业的第220位.

The target of information-based enterprises should be to raise productive forces and competitive power,and to obtain more economic benefits for enterprises.To do it,the established information system should be more intelligent system.Hence,it should be conscientiously considered that how to apply information technology makes professional work of enterprises more intellectualizing during design and implement of information-based system.

经过多年的计算机应用和市场积累,许多企业和机构已经建立了相对完善的OLTP(联机事物处理)系统.随着时间的推移,这些系统中积累了大量的历史数据,其中蕴含了许多重要的信息.通过对这些历史数据的分析和综合处理,可以找到那些对企业发展至关重要的业务信息,从而帮助有关主管和业务部门作出更加合理的决策.但是若要提取有用的信息,需花费大量的人力和时间,而且传统的数据库概念、方法和技术已经难以解决现在的新问题.90年代出现的数据仓库及其相关技术正是为解决这样的问题而产生的.作者就企业如何构造数据仓库及其采用的策略作了全面的讨论,并结合宝钢的情况,对数据仓库在宝钢的应用作了全面的介绍.

杭州市城站广场为预应力混凝土框架结构，建筑面积３．４万余平方米，地下１层，地上２层。地下室为８ｍ×８ｍ柱网。地上一层为１６ｍ×１６ｍ柱网，二层为８ｍ×８ｍ柱网。地上一层托二层的８ｍ×８ｍ柱网，由于一层楼面大梁跨度大，承担的竖向荷载也很大，整个结构较复...
