The extinction or appearance of these Ostracoda always occurred in a short time interval, and can be correlated locally and globally, so they are of importance in bioeventstratigraphy. This article listed six such biological events in Qaidam Basin and discussed their causes. The extinction of Cetacella reflected temperature decrease at global scale and changes of palaeoclimate zones during the latest Jurassic and the earliest Cretaceous; The rapid decline of Cypridea in the earliest Cretaceous may be a result of the strikes of small planets; at the latest middle-Eocene Austrocypris became extinct, and at Oligocene Hemicyprinotus disappeared. These events related to the changes of the geological conditions at that time. The explosion of Cyprideis at the middle-Miocene was because the rise of Qinghai-Xizang Plateau which resulted in the dry climate and development of salt lakes.

这些水生生物的绝灭或发生均很迅速，在区域或全球范围内均可对比，具有生物事件地层学意义：Cetacella属的绝灭可能是侏罗、白垩纪之交全球性的古气候降温和气候带变化在柴达木盆地的反映；早白垩世之后Cypridea的迅速衰退是地外因素灾变的结果；中始新世晚期的Austrocypris的绝灭、渐新世Hemicyprinotus的绝灭都与当时地质条件的改变存在著内在的联系；中中新世Cyprideis的爆发推断是青藏高原隆升，导致气候乾燥、湖水咸化的结果；而晚更新世晚期1。

The precipitation fluctuation influenced the changes of phenological events as well, especially in the arid and semi-arid region. There was a time lag for the response of vegetation activity to climate change, and the duration varied with scale, space and time.

For the first time we synthesized nanoscale metal hydrides of lanthanum, neodymium, samarium, dysprosium, and ytterbium with high efficiency under mild condition by complexometric catalysis instead of traditional preparation at high temperature and high pressure. It is for the first time that we synthesized lanthanide organic compounds with catalysts or initiating agents at atmosphere and ambient temperature,and some of them are new compounds. Nanometric lanthanide metal powders are prepared by thermal decomposition of the compounds in vacuum. Differently from the traditional method, size of the products prepared by our method is less than 40nm, and the activity of the reaction is very high. They are pyrophoric at atmosphere. They can make some reactions without activity or low activity show extremely high activity .We investigated influent regulations of methods, conditions to scale and special surface.

First time and tide kiss intimate contact, be 2002 end, the company begins sortie in those days wireless and proliferous business, basically be of LBSposition service, at that time, home have not large-scale this service is begun in wireless domain, traditional positional service is confined to use GPS to be in the industry, and the service is singler, cannot satisfy popular requirement far.

第一次和浪潮亲密接触，是在2002年末，那时公司开始涉足无线增殖业务，主要是LBS，当时，国内尚未大规模在无线领域开展此服务，传统的位置服务仅限于使用GPS在行业中，且服务比较单一，远远不能满足大众的需求。

This paper mainly studies the application of distributed control system in rubber sulphuration, and design out a set of small-scale DCS that can collect the temperature in the steam pipeline in real time, calculate equivalent time of sulphuration with different temperatures and communicate with low-computer through RS-485 network to control numbers of sulphuration machines to work.

As the internationalization of modern business development , especially in the field of retailing, it's necessary for enterprises to establish branches in a national even a world wide scale which calls for a rush improvement in management. At the same time, the large amount of the goods storage and the huge building areas make the goods merchandise inventory become remarkably complicated which result in high cost and inefficiency. What's more, data recording is a tremendous and time-consuming work as well as data analyzing if made manually; moreover, the monitor of the cameras yet cannot perform in an all-round way leaving some of the places unmonitored.

现代商业发展的模式渐渐走向国际化，特别是在零售业这一方面，在全国乃至全世界各地设立分支机构已经是企业发展的必经之路，因而在管理模式上迫切需要得到改进；而在此同时，现代商场庞大的货物存储总量和巨大的建筑面积使得商品盘存变得极为复杂，商场货品盘存高成本低效率；人工记录数据不仅工作量大，进行数据分析时也是一项费时费力的工作；同时由于摄像头的监控难以实现全方位，有不可避免的死角存在。

The thesis emphasizes the planning management practice, and at the same time according to the cognitive route of "practice—theory—practice", grasps mainly the space influencing mechanism of city growth management. Based on the content of the growth management——including the location, speed, scale and mode of city development, the thesis analyzes empirically the mechanism of location choice, sequence control, speed adjustment and gross control, and stresses the logical relation between city growth management and urban growth and evolvement. Taking space as angle of view and focalizing on strategy, the research combines space-planning strategy with the analysis of the game between different stratum. It applies to the emending of city master plan in good time, and has proved practically effective.

Following, a experiment has been carried out, the incident waves with a frequency band of 200kHz-3 50kHz are used to the experiment, and a series of peak value-time curves are drawn each 10kHz, corresponding time are found through fitting peak value, thus the position of the defect is calculated accurately. The application of awl-shaped sensor head in the heat change water pipe experiment indicates that the ultrasonic guided waves may transmit nearly 50 meters in the pipe, which is not influenced by the elbows and makes it possible to test defects in long distance and large-scale. The water-load pipe experiment indicates that the displace and energy maybe leakage at the near-surface, which is significant for the further research.
