摘要
为了解大仓鼠的耗氧情况,试验测定了大仓鼠在15,20,25,30℃下的耗氧量。试验结果表明,在15-30℃范围内,大仓鼠的耗氧量和耗氧率是随环境温度的升高而减少;初步判断体质量与耗氧量和耗氧率呈反比。大仓鼠的耗氧量和耗氧率与温度均呈线性回归关系,并得到温度t与耗氧量x0（mL·h-1）的一元线性回归方程：x0=-13.412t＋502.82,温度t与耗氧率Q0（mL·kg-1·h-1）的一元线性回归方程Q0=-105.75t＋4 255.5。大仓鼠的耗氧率随温度而发生变化说明大仓鼠的能量代谢随外界温度的变化而改变,在20-25℃梯度内耗氧量变化较少,这个温度可能更适合大仓鼠生活。
In order to study the oxygen consumption of Cricetulus triton, we measured the oxygen consumption of Cricetulus triton under 15, 20, 25, 30 ℃ respectively. The results showed that the oxygen consumption and oxygen consumption rate of Cricetulus triton were decreased with the increased ambient temperature; we concluded that the weight was inversely proportional with the oxygen consumption and the oxygen consumption rate. Linear regression relationship existed between the oxygen consumption, the oxygen consumption rate of Cricetulus triton and temperature. Besides, we obtained the simple linear regression equation of oxygen consumption and temperature which was x0=-13.412t＋502.82. The simple linear regression equation of oxygen consumption rate and temperature was Q0=-105.75t＋4 255.5. The phenomenon that the oxygen consumption rate of Cricetulus triton changed with temperature showed that： Cricetulus triton had different energy metabolism in different ambient temperature. 20-25 ℃ may be more suitable for Cricetulus triton to live for the variation of oxygen consumption was less.
