| 2 | 盆地演化认识中的几个问题显示文摘本文论述了盆地演化认识中的几个主要问题。一是陆缘裂解过程,华南边缘传统上认为是被动裂谷边缘的一个例子,其东部沉积物记录了压实的历史,它明显不同于被动裂谷作用模式,而是显示早第三纪大规模上隆和侵蚀的特征;而且,该地区覆盖在下地壳楔形体上面,具有比周围地壳明显要高的地震速度和密度,指示岩浆底侵作用。这些证据说明,与被动裂谷作用模式相比,华南边缘与主动裂谷作用模式较为一致,它是由早第三纪华南边缘东部底下地幔柱形成的主动裂谷。另一个问题是关于页岩的浅部破裂作用机理。大多数研究者认为,微裂隙的形成需要高孔隙压力,它限于深埋、低渗透率的岩石。然而,最近从北海观察表明,在第三纪页岩中,整个盆地范围内的破裂型式从未达到大于几百米的埋藏深度。这说明泥质源岩经历了水压破裂和浅部脱水,在破裂前可能达到深埋后生作用所需要的深度,实质上渗透率的改变是由于源岩的浅部破裂作用可能根本上改变了烃类的初次运移时间和效率。 | Wang Chiyuen(Department of Geology and Geophysics University of California,Berkeley,CA 94720)Yang Jiaming Zhu Weilin(Exploration and Development Research Center,China National Offshore Oil Corporation,Xincheng,074010)Zheng Mingling(Scientific Research Ce | 1995 | 地学前缘1995，2，3： | 14 |
| 3 | Landuse/landcover changes in Zhangye oasis of Hexi Corridor显示文摘Taking two f alse color composite Landsat 5 TM (Thematic Mapper) images of band 4,3,2 taken in 1995 and 2000 as data resources, this paper carried out study on LUCC of Zhan gye oasis in recent five years by interpretation according to land reso urces classification system of 1:100,000 Resources and Environmental Data base of the Chinese Academy of Sciences. The results show that great changes have taken place in landuse/landcover in Zhangye oasis since 1 995: (1) Changes of landuse structure show that cropland and land for urban c onstruction and built-up area increased, on the contrary, water area an d grassland decreased. These changes reflect the deterioration of eco-e nvironment and the acceleration of urbanization, and also indicate the problems existing in the arrangement of water and land resources betw een the upper and lower reaches of the Heihe River. (2) Regional diff erences of landuse/landcover are evident, characterized by following asp ects: in Sunan County located in Qilian Mountain area, unused land an d grassland decreased, but cropland and land for urban construction an d built-up area increased. In Minle and Shandan counties located in f oothills, unused land, water area and cropland decreased, but grassland and land for urban construction and built-up area increased. In Zhan gye City, Linze County and Gaotai County located in plain area of th e middle reaches of the Heihe River, unused land, water area and gra ssland decreased, while woodland, cropland and land for urban construction and built-up area increased. | MENG Jijun,WU Xiuqin,LI Zhengguo(Department of Urban and Environmental Scien ce, Peking University, Laboratory of Analysis and Simulation of Earth Surface P rocesses, the Ministry of Education, Beijing 100871, China) | 2003 | Journal of Geographical Sciences2003，13，1： | 9 |
| 4 | DYNAMIC RESPONSE OF ROLLER GEAR INDEXING CAM SYSTEM CONSIDERING CLEARANCE AND MOTOR CHARACTERISTIC显示文摘The dynamic responses of roller gear indexing cam mechanism are investigated .With applying Lagarange equation and Gear method,motion equations of this mechanism including clearance,motor characteristic,torsion flexibility are developed and solved.The results show that clearance affects primarily the response on turret,and has little effects on the responses on rotary table.At the same time,the velocity fluctuation of motor shaft is not serious for the existence of inertia of reducer,and the high frequency of velocity fluctuation of camshaft is related with the torsion stiffness of shaft and the clearance between pairs. | Chang Zongyu Civil Aviation College,Nanjing University of Aeronautics and Astronautics Zhang Ce Yang Yuhu Wang Yuxin Tianjin University | 2001 | Chinese Journal of Mechanical Engineering2001，14，2： | 3 |
