数九寒天,北风呼啸,天寒地冻,寒风刺骨。每当此时,人们一旦触摸到冰块就会感到透心彻骨的寒冷,这是因为冰块的温度比较低的缘故。我国北方地区最低气温可低至-20℃以下,而在地球的两极则更加寒冷。在地球上,最冷的地方是南极,有记录的最低气温为-88.3℃,因此南极又被人们称为“世界寒极”。在月球背着太阳的一面,温度竟然低到-183℃。在太阳系里,离太阳最远的是冥王星。据估测,它的表面温度可低到-240℃以下。科学家们根据大量的实验推测,宇宙深处的温度则更低,可低至-270℃左右。
Number nine cold days, the north wind roar, frosty, blusher. Whenever people touch the ice at this moment, they feel a bitter cold, because the temperature of ice is relatively low. In northern China, the minimum temperature can be as low as -20 ° C, while the poles on Earth are even colder. On Earth, the coldest place is the Antarctic. The lowest recorded temperature is -88.3 ° C. Therefore, the Antarctic is also called “the world’s coldest”. Carrying the sun on the moon’s side, the temperature was as low as -183 ℃. In the solar system, the farthest from the sun is Pluto. It is estimated that its surface temperature can be as low as -240 ° C. Scientists have speculated on the basis of a large number of experiments that the temperature in the deep universe is even lower, which can be as low as -270 ° C.
