In most of the distributed environments, the message is the way that they are communicated α with each other. But they can not be guaranteed to arrive at the right time. In this paper, we discuss the save functions in the Specification and Description Language (SDL) language. With these functions, a new way of transferring message can be realized reliably and efficiently. Finally, we give the simulation result according to the tools—? 玈DT .展开更多

A daily water balance component data including rainfall, percolation, and overflow through the paddy field levee were collected from experimental paddy rice fields during rainy season cultivation. Results show that paddy field was very effective in flood reduction. More than 40% of rainfall could be stored in the paddy fields. However, the effectiveness of paddy fields in flood reduction was highly depends on the WSI technique used. Semi dry cultivation technique was the most effective one in terms of flood reduction. It retained the rainfall up to 55.7% (365 mm) of the total rainfall (636 mm) without reducing the yield. In terms of flood volume reduction, the alternate wetting and drying performed similarly with traditional continuous flooding, i.e., 37.2% and 40.8%, respectively.展开更多
