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：目的：观察推拿结合牵引治疗青少年颈椎反弓的，临床疗效。方法：对40例青少年颈椎反弓患者进行推拿结合牵引的治疗。隔天治疗1次，10天为1个疗程，治疗2个疗程后评价疗效。结果：治疗前后颈椎曲度有显著改变，治疗后颈椎反弓纠正15例，明显改善20例，好转5例。结论：推拿结合牵引是治疗青少年颈椎生理曲度异常的有效方法。
