通过第3代谱数值波浪模型(Simulating Wave Nearshore, SWAN)预测和估计波浪特性.数值模拟选取2个区域,首先计算85°E ~100°E, 8°N~22°N的大区域,网格数181×169,精度为0.05′×0.05′,然后计算94°E ~98°E, 15°N~18°N的小区域,网格数为49×37,精度为0.05′×0.05′,后者嵌套在前者中.仰光港作为缅甸主要的贸易中心,位于嵌套区域.大区域的SWAN运行结果为小区域计算提供边界条件. 相似文献

Satisfying information needs with multi-document summaries 总被引:2,自引:0,他引:2
Generating summaries that meet the information needs of a user relies on (1) several forms of question decomposition; (2) different summarization approaches; and (3) textual inference for combining the summarization strategies. This novel framework for summarization has the advantage of producing highly responsive summaries, as indicated by the evaluation results. 相似文献
