同熱劑(一種有機(jī)磷殺蟲劑)

One possible division is between homeotherms and poikilotherms. 一種可能的劃分是恒溫動(dòng)物和變溫動(dòng)物。

One problem with this classification is that even classic homeotherms experience periods of reduced temperature. 這種分類的一個(gè)問題是，即使是典型的恒溫動(dòng)物也經(jīng)歷了降低體溫的時(shí)期。

An organism that generates heat to maintain its body temperature,typically above the temperature of its surroundings;a homeotherm. 恒溫動(dòng)物能產(chǎn)生熱量維持體溫的生物體，其體溫典型高于其周圍環(huán)境的溫度;溫血?jiǎng)游?/p>

An organism that generates heat to maintain its body temperature, typically above the temperature of its surroundings;a homeotherm. 恒溫動(dòng)物能產(chǎn)生熱量維持體溫的生物體，其體溫典型高于其周圍環(huán)境的溫度；

Therefore the next distinction was made between animals that maintain a constant body temperature, called homeotherms,those whose body temperature varies with their environment, called poikilotherms. 因此又出現(xiàn)了恒溫動(dòng)物(即保持恒定體溫的動(dòng)物)和變溫動(dòng)物(即體溫隨外界環(huán)境的變化而改變的動(dòng)物)這一區(qū)分方式。
