...According to SMM observations, the solar constant changes with a period of about 5 minutes, and the magnitude of the oscillation is about 5 millionths of the value of the solar constant. C. Pouillet (1790-1868), who first performed a fairly accurate measurement of the solar constant in 1837, had a blackened silver plate absorb sunlight and convert the heat into a rise in the temperature of water, obtaining a value of 1.76 cal/cm2・min. Meanwhile, around 1843, A. J. Angström devised a method in which sunlight is irradiated onto one of two metal plates, and an electric current is passed through the other to heat it, and the current value is measured when the two temperatures become equal. ...

…なお,SMMの観測によると,太陽定数は約5分の周期で変化しており,その振動の大きさは太陽定数の値の100万分の5程度である。 太陽定数のかなり正確な測定を1837年に最初に行ったプイエC.Pouillet(1790‐1868)は,黒く塗った銀板に太陽光を吸収させ,その熱を水の温度上昇に変えて1.76cal/cm2・minという値を得ている。一方,43年ころA.J.オングストレームは,2枚の金属板の一方に太陽光をあて他方に電流を通して暖め,両者の温度が一致するときの電流値を測る方法を考案した。…
