A study on temperature affect the energy budget of Haliotis diversicolor aquatilis

在摸拟自然条件下,设定5个温度梯度(15、19、23、27、31℃)进行了室内水族箱养殖,结果表明,九孔鲍(Haliotis diversicolorsuperrtesxa)的生长能和代谢能随温度的增加而增加,高于此温度时则相反,呈负相关关系。在温度为27℃时,九孔鲍的生长能占摄食能的比例达到最大值。九孔鲍在各温度下的能量收支方程为:15℃:100(C)=18.05(F)+8.00(U)+7.91(M)+39.60(R)+7.14(Psh)+9.36(Pg)+9.9419℃:100(C)=19.89(F)+12.24(U)+7.97(M)+33.74(R)+6.62(Psh)+9.54(Pg)+10.0123℃:100(C)=17.43(F)+12.93(U)+7.04(M)+33.79(R)+6.20(Psh)+10.25(Pg)+12.3727℃:100(C)=15.56(F)+11.03(U)+7.05(M)+28.53(R)+13.67(Psh)+16.12(Pg)+8.0331℃:100(C)=18.82(F)+13.87(U)+12.52(M)+38.44(R)+12.35(Psh)+13.62(Pg)-9.62从能量收支方程中看出,只有小部分能量用于生长壳,一部分能量用于生长软体肉能,绝大部分能量用于代谢,还有一小部分能量用于排泄、排粪和分泌粘液。Based on the study on the culture of Haliotis diversicolor aquatiliis with the different temperatures(15,19,23,27,31℃) under simulated natural conditions,the experimental data showed that the individual grow energy(P=Psh+Pg) and metabolism energy(R) could increase with the increase of temperature,but the negative relation occurred at higher temperature.The ratio of Grow energy(P) to Consumption energy(C) of Haliotis diversicolor aquatilis could get the peak at 27℃.The relationship between feces(F),excretion energy(U),mucus energy(M),metabolism energy(R),shell energy(Psh) and somatic energy(Pg) of the energy budgets under different temperatures could be denoted as:15℃:100(C)=18.05(F)+8.00(U)+7.91(M)+39.60(R)+7.14(P_(sh))+9.36(P_g)+9.9419℃:100(C)=19.89(F)+12.24(U)+7.97(M)+33.74(R)+6.62(P_(sh))+9.54(P_g)+10.0123℃:100(C)=17.43(F)+12.93(U)+7.04(M)+33.79(R)+6.20(P_(sh))+10.25(P_g)+12.3727℃:100(C)=15.56(F)+11.03(U)+7.05(M)+28.53(R)+13.67(P_(sh))+16.12(P_g)+8.0331℃:100(C)=18.82(F)+13.87(U)+12.52(M)+38.44(R)+12.35(P_(sh))+13.62(P_g)-9.62According to the equations of the energy bugets,growth energy comprised only little parts of the consumption energy;respiration energy comprised major parts of the consumption energy;the feces energy and excretion energy,mucus energy comprised the rest parts of the consumption energy.福建省自然科学基金项目(B0110035

梯形花键轴的刀具解析与近似替代

梯形花键具有导向性好、自动定心等特点，在低速、大转矩传动领域有一定的应用。应用齿廓法线法对梯形花键轴的滚刀齿廓进行了公式解析，同时对其成型刀具截型进行了公式推导。分析梯形花键副的应力集中问题，提出并计算了替代梯形外花键的渐开线齿形，并计算了齿廓偏差，为相关零件的国产化及使用提供一定的参考
