Abstract
Observations of Venus made during 1967 and 1968 at a frequency of 15.4 gigahertz set an upper limits of 5 percent for the variation of brightness temperature with phase. This negative result appears to contradict earlier detections of a phase effect. By comparison with Virg A (3C 274), which has an assumed flux density of 29 x 10(-26) watt per square meter per hertz, the brightness temperature of Venus at this frequency is 485 + 60, -40 degrees K (mean error).
摘要
在 1967 年和 1968 年，人们以 15.4 千兆赫的频率对金星进行了观测，结果得出金星的亮度温度随相位的变化幅度的上限为 5%。这一负结果似乎与早些时候探测到的相位效应相矛盾。与假定的流量密度为 29 x 10(-26)瓦特每平方米每赫兹的 Virg A（3C 274）相比，金星在这个频率下的亮度温度为 485 + 60，-40 开尔文（平均误差）。
