Charles Edouard Guillaume (1861–1928) was a Swiss physicist who received the 1920 Nobel Prize in physics for his precision measurements and discovery of anomalies in nickel steel alloys. In this work, we present a complete and commented translation of his remarkable article of 1896 on the temperature of interstellar space. The importance of this work is that it is the oldest estimate known to us of the temperature acquired by a black body, which is in interstellar space far from other stars. This temperature was presumed to be due to an equilibrium state in which the radiation received by this body from the stars around it would be equal to the radiation emitted by the body. He arrived at a temperature of 5.6 K, regarding this figure as an upper limit on the effect he was seeking to estimate. In 1926, Arthur Eddington (1882–1944) arrived at a temperature of 3.18 K, utilizing essentially the same procedure but with better data.

完整和评论翻译纪尧姆 1896 年关于空间温度的论文

查尔斯·爱德华·纪尧姆（Charles Edouard Guillaume，1861-1928 年）是瑞士物理学家，因其精确测量和发现镍钢合金异常而获得 1920 年诺贝尔物理学奖。在这项工作中，我们展示了他 1896 年关于星际空间温度的杰出文章的完整和评论翻译。这项工作的重要性在于，它是我们已知的最古老的黑体温度估计值，黑体位于远离其他恒星的星际空间。这个温度被推测是由于平衡状态，在这种平衡状态下，这个物体从它周围的恒星接收到的辐射将等于它发出的辐射。他达到了 5.6 K 的温度，并认为这个数字是他试图估计的效应的上限。1926 年，
