简介:就造房顶的短长度而言,第一的理论分析房顶流量充足基于运动学的波浪和污染物质侵蚀方程被进行。有分析答案的这数学推导预言污染物质质量首先涌出(MFF),起始的流量(MCIF)的吝啬的集中,在经常的过量降雨的条件下面在全部流量以后与起始的部分和在床表面(RS)上可得到的剩余质量的转向意味着房顶流量(MCRR)的集中。并且当参数的价值指了以前的研究时,他们上的联系影响因素(房顶长度,房顶坡度,房顶表面粗糙,降雨紧张,降雨持续时间,和侵蚀系数)的效果被讨论。结果为其长度比20m短的房顶显示出那,房顶长度的增加和在房顶表面粗糙的减少导致更大的MFF和MCIF和更小的MCRR和RS,它是有益的浇复用和污染减小。在第一之间的理论关系涌出,影响因素可以帮助以雨水利用或弥漫的污染控制计划和房顶的设计。

简介:目的将与traumatic以后癫痫观察在病人的生活的质量并且讨论影响因素。我们用生活Scale-31(QOL-31)的质量作为控制与traumatic以后癫痫和100个健康的人估计了105个病人,并且在消沉上进行了回顾的分析的方法,自我等级压抑规模(SDS)和自我等级焦虑规模(SAS),焦虑,损伤的地点,抓住的控制,EEG和治疗学的依从。有癫痫获得了的traumatic以后的结果病人很在QOL-31上比控制组降低(P<0.01),但是比SDS和SAS上的控制组高(P<0.01)。多重回归分析显示生活的质量上的主要影响因素是焦虑,治疗学的依从,消沉,损伤的癫痫的抓住和地点的差的控制。在有posttraumatic癫痫的病人的生活的质量显著地衰退了的结论。医生们应该与癫痫注意病人的心理、心理的问题,例如消沉和焦虑,提高治疗学的依从并且控制癫痫的抓住,它是改进预后的关键。
