本文以黄土高原临夏盆地巴谢河流域的上正滑坡为例,采用14C同位素年代学方法,结合文献查阅和实地走访,建立了该滑坡的多期次滑动的年代学框架.研究显示,上正滑坡至少经历了3个期次的活动:约33 kaB.P.,5～7 kaB.P.和距今约160年.这一年龄框架与此滑坡的变形破坏特征和成因机理相结合,对认识滑坡的发展演化规律有着重要的意义.这一地区普遍存在的滑坡多期次的活动,能够对这一区域的地质构造和气候演化提供科学数据,对黄土-泥岩滑坡的成因机理和演化规律加深科学认识,并能对现今的地质灾害防治措施提供借鉴.

The traditional video capture system cannot solve the problem of large image fluctuation in the video area in dy-namic environment,and its video capture interest area error is high. Therefore,a Web-based automatic capture system in video interest area in the dynamic environment was designed. The video read module in the system obtains baseband video from Web camera and executes the decryption work. The decrypted baseband video is stored as VGA format video of the dynamic environ-ment,which is then transmitted to automatic capture module. The automatic video capture module performs programming control and real-time storage operation of dynamic environment video,and provides the device interface for user's computer to realize the user′s automatic capture in video interest areas in dynamic environment. The autonomous interaction of video information ac-quired by the automatic capture module is conducted in the system backstage Web service end to independently complete the video information storage,processing and management of system resources. The automatic capture objective function in video in-terest areas in dynamic environment and the video read language the dynamic condition are given. The experimental result shows that the designed system has the advantage of low capture error.

Toppling failure of unstable rocks was analyzed using fracture mechanics.Based on tensile-shear fracture tests of rock samples,fracture initiation and propagation mechanisms under loading were analyzed,and crack propagation during the fracture process was investigated.The effects of the crack length,width,and inclination angle as well as the loading point on the failure mode and stability of unstable rocks were discussed.An overhanging rock,the Taibaiyan unstable rock in Wanzhou District of Chongqing City was used as a case study.The stress state of crack tips under different cracking conditions was calculated using the finite element software ANSYS,the relationship between the complex breaking stress intensity factor and stress state was discussed,and the dynamic process of crack propagation was simulated.Results show that,during the processes of tension,shear,and toppling failures of unstable rocks,tensile stresses were concentrated at creak tips,unstable rock cracking was first induced by tension failures,and shear-compression failures occurred at the bottom.The sensibilities of the factors to the instability of unstable rocks were ranked in an descending order as follows: the loading position,crack length,crack inclination angle,and crack width.

In the background of mass higher education,the problem of universities status management have become increasingly prominent,The traditional way of handling,already can't adapt to the characteristics and needs of college students in the new period,To establish a set of active status early warning mechanism is very necessary,it's very Important to guarantee the students' learning interest,establish a good style of study,constructing a harmonious education environment.

To apply the technology of virtual reality in designing teaching softwares the paper firstly analyzes the structure and features of Virtools.Then,based on the platform of Virtools it uses the modeling tool of 3DMax to design the teaching of Cosmic Environment and its teaching software,analyzes the problems in designing.It,finally,concludes that it is feasible and practicable to ap ply the virtual technology in developing teaching softwares.

Web-based game courseware is an innovative multimedia courseware.It is based on net game,and combines with learning.It helps learners to learn during the game,and achieve the supposed teaching goal.But it is a complex and huge task to design such courseware,because its development cycle is very long and the development cost is very high.Therefore,it is necessary to study on web-based game courseware design process.The research can enhance developing efficiency of the courseware,reduce the developing cost and popularize such courseware in the teaching.

高校文科专业开设了VB程序设计,在教学中反映出许多问题,文科学生对程序设计的学习跟理科学生有一定的差距。本文通过作者对文科VB程序设计教学实践的分析,提出了一些针对高校文科专业学习VB程序设计的教学思考。

The spatial distribution, scale and property of the Pujiang Xinjin Deyang buried fault in Fenghuangshan area were investigated by the use of seismic reflection survey technique. The result shows that the fault cut off the late pleistocene sediment in the process of eastward underthrusting, and has been significantly active since Quaternary. It has controlled to some extent the formation of the Fenghuangshan platform. Surface geological investigation and historical earthquake research have revealed that the Pujiang Xinjin Deyang buried fault were active during late Pleistocene. The activity of the south segment of the fault is obviously stronger than that of the north segment, indicating that the north segment of the fault is a zone of weak seismicity in the Chengdu Plain. At the same time, the layout of observational systems and the selection of seismic parameters for seismic reflection surveying of buried fault in densely populated suburban areas have been studied as well. It is found that the use of small group intervals, small offset, multiple channels, short array length, multiple coverage and high frequency receivers, as well as the appropriate selection of seismic parameters are of great significance to the effective separation of reflected wave from disturbing wave, and also to the improvement of the resolving power of seismic prospecting technique.
