In view of the current situation of Maoming marine ranch, although the construction of marine ranch in Maoming City has achieved certain results, there are still some problems, such as the restriction of sea use, the imperfect intelligent equipment and land supporting facilities of deep-sea marine ranch, and the problem of marine pollution in Maoming. In response to the problems, corresponding solutions are proposed. While strengthening the supervision of the later operation of marine ranch, we should do a good job in top-level design and reasonable layout, and provide good supporting services, so that the construction of marine ranch and ecological protection can be promoted simultaneously, and the healthy and sustainable development of marine ranch can be promoted.展开更多
文摘研究居住建筑采用不同保温墙体的节能效果,介绍混凝土夹心保温墙体构造,运用理论计算满足节能的最小保温厚度及其热工参数.以严寒地区某居住建筑为研究对象,通过DeST能耗模拟软件建立模型,分别研究挤塑聚苯板、岩棉、聚氨酯和真空绝热板夹心保温材料在不同厚度下对建筑能耗的影响,利用全生命周期法分析其经济性,Matlab曲线拟合净现值确定保温材料最优厚度.结果表明,4种保温材料相同厚度下保温隔热性能依次是真空绝热板、聚氨酯、挤塑聚苯板、岩棉,其对应最优厚度分别为20、50、75和90 mm.
