体温的生理调节

These findings clearly show that mammal-like endothermy is not a necessary prerequisite for ecological success.

这些发现清楚地表明了，类似哺乳动物的体温生理调节方式并不是动物实现生态学意义上的成功所必需。

DR is one of the most collective part of serotonin(5-HT) in the nerve center. It takes part in the regulation of sleep and awakening, incretion,emotion,temperture,feeding and so on, and it plays an important role in pain and electroacupuncture analgesia.

中缝背核是中枢5-羟色胺(5-HT)能神经元的主要聚集部位之一，参与睡眠与觉醒、内分泌活动、情感活动、体温及饮食等多种生理功能的调节，并在疼痛和针刺镇痛过程中起重要作用。

To better unders tand their physiological and ecological adaptations to this region, we quantifie d characteristics of their thermoregulation and thermogenesis.

为探讨它们在该地区的生理生态适应特征，对其体温调节和产热特征进行了测定。

The characteristic of the dairy cow thermoregulation was base on environment and nutrition administration technology. Study regressions of dairy cow physiology on ambient temperature, effective temperature and temperature-humidity index, the difference between the high and low yield dairy cow of the circadian rhythm about thermoregulatory at hot summer, evaluated the efficiency of half open and open dairy barn preventing heatstroke, evaluated the efficiency of temperature dropdown by sprinkler and air-cooling fan. The thesis was described in the following three sections.

奶牛体温调节特性是环境与营养调控技术的依据，本文从高温季节环境温度、体感温度和温湿指数与奶牛生理反应的关系，温热环境和体温调节特性的昼夜差异，高、低产奶牛体温调节特性，牛舍环境特征及其冷风机和喷淋降温效果等方面揭示荷斯坦奶牛的体温调节特性。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
