difference in temperature

基本解释

We don’t generally notice this difference in temperature because our eyes adjust automatically for it.
我們通常注意不到色溫的不同，因爲眼睛具有自適應能力，會對其自行調節。
This is not perpetual motion, but a type of heat engine, exploiting the difference in temperature between the air and the water it dips into.
這不是一種永動機，而是一種熱能機。通過利用空氣和水之間的溫度差來推動鳥蘸水。
But the 40C difference in temperature between the two snow-clad cities is as great as that between the coldest winter day in Britain and a sunny July scorcher in the south of Spain.
但是莫斯科和雅庫茨尅這兩個冰雪罩蓋的城市竟然有40度的溫差，就像英國最冷的鼕天和西班牙南部七月炙熱的炎夏相比。

Another reason is that a small change in temperature can mean the difference between snow and rain.

When a robot finds a cave — sensed by a difference in temperature — it returns by the shortest route, the beeline, back to the lander.

Though RNA editing has been observed before, in animals ranging from humans to nematode worms, this is the first time an edit has been tied to a clear evolutionary difference caused by a feature of the environment—in this case ambient temperature.

These pens would bob 60 feet below the surface, kept in place with motors powered by heat exchangers that use the temperature difference between deep water and shallow water to generate electricity.
