Small runoff, large sediment load, and inco.patible relationship of flow and sediment load are very important characteristics of the Yellow River. They are also the crux of the most prominent problems of the Yellow River. To solve these problems, the regimes of flow and sediment load have to be improved by increasing water, reducing sediment load, and by using reservoirs to regulate flow and sediment load. The results of experiments for regulating the flow and sediment load in the last three years by the Xiaolangdi Reservoir have indicated that this measure is a realistic and effective way to mitigate the prominent problems in flood co.trol of the Lower Yellow River at present and in the near future. However, the regulation system is still imperfect. It is advisable to speed up the pace of research and co.struction of the system for regulating flow and sediment load.

To reduce the network deployment co.t and provide voice, message and low rate data services in remote pastoral areas of Tibet effectively, an integrated wireless co.munication system utilizing MANET(Mobile Ad hoc Network) is proposed. The sparse mobile devices, assisted with the solar-powered multi-functional standing stations mainly on networking maintenance and routing arrangement, self-organize into a MANET. The topology of the standing stations is designed for networking robust and to simplify the routing method and energy strategy. Then in the OMNe T++(Objective Modular Network Test bed in C++) simulation, the energy co.sumption is analysis while adjusting routing with the different energy status of the standing stations. The result shows that the standing stations should adjust routing as well as co.trol the mobile devices' activity level acco.ding to the energy states of the standing stations and their adjacent mobile devices.

The effect of co.ling rate and austenitizing co.dition on the mechanical properties of high carbon steel (SWRH82B) has beeninvestigated. Specimens were made of high carbon steel rod and heat-treated by Gleeble-2000 to produce a wide variation in prior austenite size. Different co.ling rates were carried out, and then pearlite interlaminar spacing and mechanical properties were measured andtested respectively. Acco.ding to the results, it co.ld be found that under the co.tinuous co.ling with the increase of co.ling rate, tensilestrength greatly increases and reduction in area exhibits a slightly increase for an equivalent value of prior austenite grain size. Whenprior austenite size increases, reduction in area decreases, and tensile strength increases slightly for an equivalent value of pearlite interlaminar spacing. It is co.cluded that prior austenite size primarily co.trols ductility and pearlite interlaminar spacing co.trols tensilestrength. Mathematical formulae are given for these relations.
