中文摘要：采用室内实验生态学方法对尖紫蛤的耗氧率和排氨率进行了研究。结果表明,在16～32℃时,尖紫蛤的耗氧率和排氨率与体质量呈负相关的幂函数关系,可分别表示为OR=aW-b和NR=cW-b,其中b的取值范围为0.488～0.874,平均值为0.620;a的取值范围为0.362～1.371;d的取值范围为0.454～0.747,平均值为0.591;c的取值范围为44.678～121.158。在16～32℃时,尖紫蛤的耗氧率和温度之间的关系可以用指数函数OR=c1ed1T表示,耗氧率随着温度的升高而增加,在32℃时达到峰值,当温度超过32℃时,耗氧率下降。在16～36℃时,尖紫蛤的排氨率和温度之间的关系可以用二次多项式NR=-c2+d2T-d3T2表示,在28℃时排氨率达到峰值。尖紫蛤呼吸Q10值的范围为0.547～3.660,排泄Q10值的范围为0.235～2.515,水温对耗氧率和排氨率的影响均显著。尖紫蛤的呼吸氧原子数与排出的氨态氮原子之比O∶N值的范围为4.312～21.874,各种规格的尖紫蛤O∶N随温度的升高而升高。

外文摘要：The oxygen consumption rate and ammonia excretion rate of Soletellina acuta were examined by using the indoor experimental ecological methods. The results showed that the oxygen consumption rate and ammonia excretion rate of S. acuta had negative power function correlation with the body mass cultured at 16-32 ℃ . At 16～32 ℃ the oxygen consumption rate of S. acuta was exponentially correlated with temperature. The oxygen consumption rate increased with the temperature,reaching the peak value at 32 ℃ ,and then decreased when the temperature was over 32 ℃ . At 16-36 ℃ the correlation between the ammonia excretion rate and temperature could be expressed with a quadratic polynomial function,and the ammonia excretion rate was maximum at 28 ℃ . The Q10 value of respiration ranged from 0. 547 to 3. 660 and the Q10 value of excretion ranged from 0. 235 to 2. 515 in S. acuta. The effects of temperature on the oxygen consumption rate and ammonia excretion rate were both significant. The ratio between the respiratory oxygen atoms and excretory ammonia nitrogen atoms （O∶N） of S. acuta ranged from 4. 312 to 21. 874. The O ∶ N ratio of S. acuta with all sizes increased as the temperature rose.
