  • 简介:由生命周期评价(LCA)的申请方法论,这份报纸估计生产的环境影响和在中国在电的车辆使用的拖拉马达的处理。结果证明拖拉马达生产和处理的全部的精力使用,标准排出物和温室气体(GHG)排出物是大约2,899,MJ,4.5,kg并且259.5,kg每分别地交通。在调整排出物之中,SOx排放由全部的质量评价第一,由公司,PM10,没有x,PM2.5,和不稳定的有机化合物(VOC)列在后面。为大多数精力消费和排出物的马达材料生产阶段报道,由集会阶段和end-of-life处理列在后面舞台。在这研究,环境表演分析为材料生产阶段被扩大到在第二等的材料和主要材料的使用之间的比较。用100%,第二等的材料与百分之百主要的材料的使用相比在GHG排出物在精力消费,在调整排出物的49.8%减小,和49.3%减小导致52.9%减小,这被发现。

  • 简介:在为被动声纳的沿岸的区域的安静目标的察觉和本地化上的主要挑战是复杂声学的繁殖和表面上的大声的轮船干扰的流行。适应的匹配的地处理能提供能力给空表面干扰,而是失配在之间计算并且由于环境无常驾驶向量的实际数组,和目标和干扰的运动能显著地导致数组获得的损失。为了处理环境失配和目标的问题,运动,一个柔韧的运动赔偿算法和一个系统策划因为适应的匹配的地处理被开发了。试验性的数据的数字模拟和分析证明柔韧的AMFP计划能大声压制表面干扰并且改进为在水下的弱移动的性能在复杂的浅水里指向的察觉。
