摘要: 通过对长爪沙鼠和金黄地鼠肺皮蒸发失水量的研究表明,同种内个体间肺皮蒸发失水量与动物体重呈负指数相关。在10—30℃范围内,肺皮蒸发失水量随温度上升呈指数式增加。随着相对湿度的增加,肺皮蒸发失水量呈指数式减少。在10℃和20℃环境温度下,金黄地鼠肺皮蒸发失水量略高于长爪沙鼠,在30℃环境温度下,长爪沙鼠肺皮蒸发失水量略高于金黄地鼠。

Abstract: The pulmo-cutaneous evaporative water losses(PEL) of the mongolian gerbil (Meriones unguiculatus) and golden hamster (Mesocricetus auratus) were measured at ambient temperatures of 10℃, 20℃, 30℃ and relative humidities of 0%, 30%, 70%, 100% by the use of an open circuit system. The results are as follows:1. The PEL per unit of body weight are correlated negatively with the body weight of tested animals. For example, at 20℃ and 0% (relative humidity), logE = 1.73214 -0.93668 logW for gerbil, where E is the PEL in mg/g.h, and W is body weight in grams.2. The PEL are increased with the ascent of the ambient temperatures between 10°-30℃, for gerbil logE =-0.54945 + 0.03278Ta(r =0.995), and for golden hamster logE = -0.42446 + 0.02794Ta(r = 0.999).3. The PEL are decreased with the ascent of relative humidities of air, for gerbil E = 1.12516-0.01050% (relative humidity) (r=-0.975), and for golden hamster E = 1.32229-0.00883% (relative humidity) (r =-0.962).4. The PEL of golden hamster are only slightly higher than that of mongolian gerbil at 10° and 20℃, but at 30℃ the PEL of the later become higher.
