水可以吸收和释放大量的热量,而温度变化不大,从而创造一个稳定的环境。
Water can absorb and release a lot of heat without big changes in temperature, thus creating a stable environment.
这两种装置在阳光充足的气候条件下工作良好;但在北欧,太阳可能一次被云层遮挡数周,而温度不仅随着季节变化,而且还随着昼夜变化。
Both these devices worked well in sunny climates; but in northern Europe, the sun may be hidden by clouds for weeks at a time, while temperatures vary not only seasonally but from day to night.
身患失眠症的人通常无法调节自己的体温,而温度降不下来的话是没法入睡的。
Insomniacs often have trouble regulating their body temperatures, which must drop in order for sleep to occur.
And you already saw last time there was this relationship between the temperature and volume changes along an adiabatic path.
是条绝热路径,而上次你已经看到,沿着绝热路径温度和体积,的变化有这个关系。
So that you could see that for the ideal gas, u would not be a function of volume, but only of temperature.
所以我们可以看到对理想气体,内能不依赖于体积,而仅仅是温度的函数。
And our other reference point is the triple point of water - reference points become zero Kelvin, absolute zero, and the triple point.
而使用绝对零度,它与压强无关,是最低的温度,另一个参考点是水的三相点。
