德国怎样处理报废汽车

德国是个汽车王国，每年生产的新车接近500万辆，同时也有近150万辆旧车报废。在德国，通常使用10年以上的车就属于旧车，可以申请报废。申请报废和购买新车一样，需要到有关部门办理手续，注销车辆的登记后，方可把汽车送往指定的旧……     

日产公司处理及再利用报废车的现状的对策

报废车经处理后究竟可再利用得多少?如果按该车的总质量计算时,平均可达到75%左右.由此可见,比报废电气产品的再利用的质量比就显得高得多.

Effect of ulinastatin on hepatic ischemia-reperfusion injury in rats

Objective To investigate the effect of ulinastatin (UTI) on hepatic ischemia-reperfusion injury in rats. Methods Totally 24 adult Sprague-Dawley rats were randomly divided into 3 groups: sham-operated control group (SO group), ischemia-reperfusion group (I/R group) and ulinastatin group (UTI group). Liver in I/R group underwent 1 h of reperfasion after 30 min of ischemia. In UTI group, UTI (2×104 U/kg) was administered to rats 30 min before modeling. The levels of alanine aminotransferase, aspartate aminotransferase and tumor necrosis factor-alpha (TNF-α) in serum were measured and the levels of nitric oxide and malondialdehyde in liver were determined. The histological changes of liver were observed. Results The levels of alanine aminotransferase, aspartate aminotransferase and TNF-α in serum were significantly increased in I/R group compared with those in UTI group (P<0.05). The levels of nitric oxide and malondialdehyde in liver were significantly higher in I/R group than in UTI group (P<0.05).Histological examination of liver indicated that the damages were more severe in I/R group than in UTI group.Conclusion UTI has the ability to inhibit the production of TNF-α and oxyradical, and ameliorate microcirculatory dysfunction in rats with hepatic ischemia-reperfasion injury.     

规划地下交通设施以处理好火灾事故

利用实际火灾荷载进行的隧道防火试验得出了有关由火灾及其过程所产生的两方面危险的重要成果。对新结构和再开发既有旧道路、大块墙体隧道的规划原则进行了讨论。而最首要的，是提供了避免隧道衬砌损坏的设计建议。谨以此文献给在本领域以其工作赢得了特别声誉的Horst Falkner教授，在他65岁生日之际。
