- 为什么绝对零度正好是-273. 15度? - 知乎
绝对零度正好是-273 15度，其实是人工定义的，为啥要这样定义呢？ 那就说来话长了。 温度是一种用来表示物体冷热程度的物理量，想要讨论温度，首先就得给温度定义一个计量单位，怎么定义呢？
- 绝对零度真的是精确地「等于」 -273. 15 ℃ 吗？ - 知乎
绝对零度为0K，楼主的问题更清晰等价于：“为什么水的三相点是273 15K”。 1。这取决于温度单位的定义，把三相点到沸点进行100等分，定义每一个等分为一个单位，于是产生了单位1摄氏度的概念。 2。计算水的三相点到绝对零度相差多少个这种温度单位，计算得到273 16个单位。于是绝对零度就是-273
- 为什么低温只能达到 -273. 15℃，而高温可以达到上亿亿摄氏度？
而最低温度-273 15℃，即0K（绝对零度），就是微观粒子完全静止下来的温度，至于这个温度为什么大小为-273 15℃，这只是我们选择一种温度定义标准（温标）而已，即我们把水的三相点温度定义为273 16K。
- 273 V-8 for 1980-82? - Allpar Forums
The 273 was long gone by 1980, when Chrysler was on its knees, surviving largely on the F M J line of cars The guaranteed loan funds were invested in the K-cars, K-car derivatives, the L-bodies, and M-bodies Spring of 1980 was extremely rough, financially, for Chrysler Corporation and North America in general

- 为什么把水三相点的温度规定为273. 16K，这个数值是怎么确定的？ - 知乎
为什么把水三相点的温度规定为273 16K，这个数值是怎么确定的？ 或者说物理界是怎么在实验室中模拟出接近绝对零度的温度的？

- Headers for 273 - Allpar Forums
Does anyone know if there are any headers available for the 64 Valiant with the 273? I cannot seem to find anything available, or at least every place I have looked I'm told they are unavailable due to the steering box being in the way If there is something that will work, any info would be great!
