In the Longmen Mountain fault zone, which is located 40 miles from the earthquake center at Wenchuan, the Chinese military used a variety of treatment methods to rescue the injured and successfully treated a victim with severe traumatic brain injury (TBI) who survived without food or water intake for 192 hours. Two hundred and twenty-four hours after the earthquake, the patient underwent craniotomy and removal of an intracerebral hematoma. The injury to the patient was severe and the rescue time was the longest for this earthquake. Detailed information is provided in this report.展开更多

文摘Desulfurization and denitrification by using ozone has been widely used in recent years,but the technology for generating ozone at this stage has some shortcomings,which needs to be improved urgently.This paper advocates using mud-phosphorous slurry to produce ozone,which is environmentally friendly and economical.At the same time,SO_(2) and NO_(x) can be removed from mud-phosphorous slurry simultaneously.The amount of ozone generated during desulfurization and denitrification is particularly important,thus,this paper studies the effects of the temperature of reaction,oxygen content and solid-liquid ratio of mud-phosphorus slurry on the amount of ozone generated.The results showed that under the optimum conditions(the reaction temperature was 60℃,the solid-liquid ratio of mud-phosphorus slurry was 5.0 g/40 mL,the oxygen content was 30%),the amount of ozone was the largest,and the maximum generation amount was 573.8 mg/m^(3).Under these conditions,the removal rates of SO_(2) and NO_(x) can reach 99.5%and 99%respectively.This paper also analyzes the products of desulfurization and denitrification,and proposes the corresponding reaction mechanism.
