Study on gis data directly integrated into image processing

The basic properties to be dealt with ,when considering initially the research needs related to the integration of remote sensing (RS) information into a geographic information system (GIS),are many-sided.The primary combination of remote sensing and GIS is mainly realized by the transforms of data structure .Because of its own limitations,there is an urgent need to investigate the integration of RS and GIS in higher levels.In this paper,we discuss the different types of combinations of RS with GIS,and propose that GIS data should be directly brought into image processing from the beginning.A tentative idea of how to use the method of granularity to study the common processing unit of RS and GIS is described.The example for the determination of granularity of spatial data processing related to run-length-code line is also given.

ENSO循环与低纬度大气的正压和斜压运动

利用一个２层海洋模式和ＧＩＳＳＴ资料、ＮＣＥＰ再分析资料,对大气正压／斜压运动与ＥＳＮＯ循环之间的联系进行了研究。结果表明,在赤道中、东太平洋地区,大气斜压模在ＥＮＳＯ时间尺度上的变化位相略超前于正压模的变化,正压模的变化位相超前于ＳＳＴＡ变化,ＳＳＴＡ变化位相超前斜压模的变化位相。斜压纬向风异常与ＳＳＴＡ具有正相关关系（西太平洋西部相反）;正压模则与Ｎｉｎｏ３区海温异常有负相关关系（西太平洋西部     

Building vibrations and dynamic pavement loads induced by transit buses

The purpose of this study was to investigate the effect of bus suspension systems on building vibrations and dynamic pavement loads. Building vibrations and pavement loads induced by two instrumented buses having different characteristics were measured simultaneously under controlled field conditions. Field tests were performed at several vehicle speeds, normal and reduced tire pressures, and with roads having good surface condition as well as abrupt surface irregularities. Tests were carried out at two vibration complaint sites in Montréal. The level and frequency content of vibrations and loads induced by the two buses were evaluated and compared. The results show that the dynamic component of pavement loads induced by the two buses were significantly different but the difference in building vibration levels was not as significant.     

兴隆庄煤矿3煤顶板岩层富水性分区

分析了矿井顶板水害及防治现状,以兴隆庄煤矿４３１８工作面为例,用信息拟合方法对顶板富水性进行分区,应用模糊评判预测方法进行了顶板水量预测计算：涌水量等级为３级,正常涌水量为０．５～１．５ｍ＾３／ｍｉｎ,最大涌水量为２．２５ｍ＾３／ｍｉｎ,与实际涌水量一致。     

西藏它日错地区多巴组沉积环境及石油地质意义

西藏它日错地区是中特提斯的一个重要深坳陷区,发育了巨厚的下白垩统海陆交互相和浅海碳酸盐岩沉积,其中多巴组厚度超过了地５００ｍ,主要沉积相类型包括陆源碎屑湖坪相、碳酸盐浅海、水下浅滩,混合沉积过渡带等,在它日错一带形成坳陷中心,主要物源从南、西南方向进积,多巴组的烃源岩主要为浅海相地,向它划方向增多、加厚、有机质类型为混合型,可能的集集岩是浅滩相介壳灰岩、浅海相泥晶灰岩及潮坪相砂岩,裂隙是其主要的储集空间,而潮下带泥岩则可成为有利盖层,垂向上由于多旋回叠加,具有较好的生储盖盖组合,但所发现的烃源岩厚度较薄是其不利因素。

地壳的拆离作用与华北克拉通破坏:晚中生代伸展构造约束

伸展条件下的地壳拆离作用是岩石圈减薄的重要浅部构造响应。晚中生代时期的伸展构造(包括拆离断层、变质核杂岩构造和断陷盆地)在华北、华南、东北和东蒙古及贝加尔地区普遍发育,它们切过上部地壳(断陷盆地)、中、上地壳(拆离断层)或中部地壳(变质核杂岩)。地壳拆离作用具有运动学极性(NWW或SEE)、几何学宏观(区域)对称与微观(局部)不对称性、遍布全区但不均匀性,以及形成时间的跨越性(140~60Ma)等特点,并使得地壳和岩石圈发生显著的减薄。本文研究揭示出现今岩石圈厚度变化与晚中生代伸展构造的发育程度和分布之间并没有必然的联系。其变化的基本规律是,除新生代裂陷发育区岩石圈厚度明显较小且厚度有迅速变化外,从华北向贝加尔地区总体的变化趋势是逐渐加厚,也即东亚地区岩石圈具有楔形形态。晚中生代时期的地壳(或地幔)拆离作用伴随着广泛的岩石圈减薄作用,区域岩石圈同时遭受到一定程度的减薄和破坏,华北克拉通在这一时期的破坏仅仅是区域岩石圈减薄在华北的具体体现。
