All the analysis was done using SAS EM 4.1 software. The prevalence of tracheobronchitis were higher in spring and autumn. Average atmospheric pressure, average temperature, highest air temperature, lowest air temperature, water-vapour pressure, degradation of visibility were positively correlated with the prevalence of tracheobronchitis. Factors that affected the incidence of tracheobronchitis were average atmospheric pressure, degradation of visibility, daily temperature difference and water-vapour pressure.

The SOD and the LDH-1 activities and EST (R_f=0.17 and R_f=0.72) at 1℃weresignificantly higher than the values of the room temperature(P＜0.05), but the total enzymeactivities of LDH, G6PDH and EST at room temperature and 1℃were similar(P＞0.05).This showed well-developed anoxia tolerance of the Heilongjiang wood frog to maintainplasma viability when low temperature interrupts the delivery of oxygen and substrates. LDH-1rose significantly avoided the liver lactic acid accumulation that may created the liver to bewearied. EST (R_f=0.17 and R_f=0.72) rose may enhance the ester metabolism to offer muchenergy. These showed steady metabolic rate and relative stable organism environment of theHeilongjiang wood frog to survive under low temperature.Native PAGE separated proteins of liver tissue successfully on the better condition is 6％final gel concentration and there were 15～19 bands identified on this condition.

When the pouring temperature is close to the liquidus temperature of AlSi7Mgalloy, the primary α-Alin the billets of AlSi7Mg alloy solidifies into spherical or nodular grainswhich are small and distributed homogeneously. In order to obtain non-dendritic semi-solidbillets,the appropriate pouring temperature is 615℃. The faster cooling rate,the melt flowing and largersolidification region induced by the near liquidus pouring temperature promotes theformation of spherical or nodular primary α-Al.
