Incineration experiment of medical waste was carried out in a mobile animal carcass *** medical waste(69%cotton,1.5%wood product,4.5%mask and 25%moisture)was used as raw *** temperature trend of first and second combustion chamber,the operating conditions and the emission characteristics of gaseous pollutants were *** results indicated that the temperature of first combustion chamber can be maintained at 550-650℃ without external heating,while in the final stage a burner was used to realize the burnout of *** temperature of the second combustion chamber was always lower than that of the first combustion after the burner stopped *** concentration of CO emission in flue gas was high due to the low disposal efficiency of the mobile incinerator,while NOX and SO2 emission concentrations were far below the standard limit value(GB 18484-2001).

Global climate change has been considered to be one of the key factors leading to declines and losses of amphibian *** global warming is one of the acknowledged causes of fluctuations of amphibian population worldwide,unseasonal sharp fall in air temperature as result of global climate change may also affect the survival and stability of amphibian population *** this article,we have investigated how temperature fluctuation affected the physiology of giant spiny frog (Paa spinosa).The winter temperatures experienced by wild giant spiny frog in natural winter in the local Mountain of Kaihua in Zhejiang Province was monitored,and then replicated in subsequent *** frogs were divided into two groups,one group served as a control maintained at 22℃, a second group of frogs were subjected to a temperature fluctuation of cold shock(4℃/12h)and recovery(22℃/12h)for seven *** frogs were sampled after 4h,12h cold shock,12 h recovery at first day and after 12h cold shock,12h recovery at seventh *** results showed that the survival temperature range of wild overwintering was between 0℃-14℃in 12/1/2009-3/31/2010,and minimum and maximum temperature ranged between 0℃-4℃and 10℃-14℃respectively. Upon temperature fluctuation,no statistically significant differences were found in the control groups of all parameters at any time of the *** respiratory burst of spleen macrophages and the peripheral blood phagocytic activity were both inhibited after cold shock,and restored to control level after recovery at 22℃at the first day,and remained the level after temperature fluctuation for seven *** gastric lysozyme activity and the relative hsp70 intensity showed similar results except significant decrease in comparison to that of the control group at the seventh *** malonaldehyde (MDA)content,the glutathione(GSH)content and the activity of superoxide dismutase(SOD)of liver were significantly increased after cold shock for 4h,and th
