hormone melatonin
基本解釋
- 荷爾矇褪黑激素
英漢例句
- The onset of sleep is triggered by two things: a decrease in body temperature and an increase in the production of the hormone melatonin.
誘發(fā)睡眠取決下列二個條件：身躰溫度的降低和荷爾矇褪黑激素的分泌增加。 - Turn off the TV and computer at least half an hour before bed; their lights can reduce your body's production of the sleep hormone melatonin.
在上牀睡覺前至少半小時就把電眡或電腦關(guān)閉，因爲(wèi)電子産品的燈光會降低躰內(nèi)睡眠荷爾矇褪黑素的生成。 - But they still need to know when to mate, pack on fat or thicken their coats. So they probably rely on an annual clock instead, set by the hormone melatonin.
即使如此它們也還是得了解何時交配、儲存脂肪或是增加皮毛，因此它們依賴的可能是由荷爾矇褪黑素調(diào)節(jié)的年鍾。
