简介:英国著名跑车品牌Lotus(路特斯)的升级版超级跑车.车身使用了大量碳纤维材质,且全部为纯手工打造,非常有效地降低了车重,其外观设计延续了Lotus跑车系列标志性的家族式设计.轻量化设计对新车的性能提升起到了很大的作用,重新校准和调整的3.5升排量的V6机械式增压发动机加上经过升级改造的空气动力学配置保证了高速行驶时的稳定性,可以在赛道上表现出更好的高性能.
简介:THENEWCARCHALLENGE新上市的宝马5系固然很棒,但你们不觉得这类车型越来越中庸,越来越无聊了吗?对于骨子里是个不安分的人来说,花差不多的钱绝对会选择辣味十足的钢炮,比如今天对决的这两款.自我介绍高尔夫家族最最强悍的车型思域家族最最强悍的车型亮点已经是最快的“神车”了,还需要别的亮点吗在人人都以刷纽博格林赛道纪录为荣的当下,我们吃不准新思域TypeR是不是最快量产前驱者纪录的创造者或者保持者,只知道它的成绩是7分43.8秒.
简介:摘要NOx是大气的主要污染物之一,对环境的损坏作用极大,它是形成酸雨以及大气中光化学烟雾的主要物质。在国家“十二五环保规划”中,NOx成为继SO2之后,被列入实行总量控制的污染物,最新出台的《火电厂大气污染物排放标准》(GB13223-2011)明确规定,2004年后新建的燃煤锅炉,烟气中NOx的排放限值100mg/m3。选择性催化还原(SCR)烟气脱硝技术,因脱硝效率达90%,成为火电厂在采用低氮燃烧技术上进一步控制NOx排放的首选工艺。但是采用SCR脱硝技术的锅炉在运行中出现了局部氨逃逸过高、空预器因硫酸氢铵堵塞问题,严重威胁机组的安全运行。本文结合SCR脱硝装置运行实例就该问题的产生和如何解决展开研究,以获得一个良好的解决方案保证设备的稳定运行。

简介:摘要目的探讨对比不同胰岛素(甘舒霖30R、诺和灵30R)对糖尿病的治疗效果。方法选取我院2015年9月-2016年9月收治的患有糖尿病的104例患者,对其采用数字抽签法分组,对照组给予甘舒霖30R治疗,观察组给予诺和灵30R治疗,比较其血糖控制效果和不良反应情况。结果两组患者血糖指标之间差异不明显(P>0.05),无统计学意义。两组患者不良反应发生率分别为1.9%、3.8%,没有差异和统计学意义(P>0.05)。结论糖尿病患者采用甘舒霖30R和诺和灵30R治疗的临床效果相似,不良反应发生率低,具有操作方便、注射次数少、安全、有效控制血糖等作用,值得在临床上使用。
