对于医学生来说，进行医学英语学习是非常有必要的，因为在工作中会涉及到很多国内外的最新医学信息。下面是小编整理的发热fever的资料，希望对你有所帮助！

发热fever

　　Fever

　　发热

　　Fever is a physiologic state in which the body temperature is elevated above the individual’s normal temperature, usually over over 100°F (37.8°C).

　　发热是指体温升高超过个体正常温度的一种生理状态，通常指华氏100度或摄氏37.8度以上。

　　A healthy person's body temperature fluctuates between 97°F (36.1°C) and 100°F (37.8°C), with the average being 98.6°F (37°C). The body maintains stability within this range by balancing the heat produced by the metabolism with the heat lost to the environment. The "thermostat" that controls this process is located in the hypothalamus, a small structure located deep within the brain. The nervous system constantly relays information about the body's temperature to the thermostat, which in turn activates different physical responses designed to cool or warm the body, depending on the circumstances. A fever occurs when the thermostat resets at a higher temperature, primarily in response to an infection. form www.med66.com

　　健康者体温波动范围为97°F (36.1°C)至100°F (37.8°C)，平均98.6°F (37°C)。机体通过自身代谢产生的热量与环境消耗热量之间的平衡来使体温稳定在该范围内。控制该过程的“调温器”位于下丘脑，大脑深处。神经系统不断向这个“调温器”传递机体温度信息，再由“调温器”根据不同情况，激活各种生理反应，冷却或加热机体。当“调温器”设置处于较高端时，就会出现发热现象，它主要是对感染所作的一种反应。
