首次对金星低层大气进行了气相色谱分析。分析了三种大气样品。第三个样品显示二氧化碳（96.4%），分子氮（3.41%），水蒸气（0.135%），分子氧[百万分之69.3（ppm）]，氩（18.6 ppm），氖（4.31 ppm）和二氧化硫（186 ppm）。探测到的水蒸气和二氧化硫的数量大致符合金星高表面温度温室模型的要求。从云层顶部到底部的二氧化硫、分子氧和水蒸气的大的正梯度，正如地球上的观测和这些结果所暗示的那样，为云层中存在大量的含水硫酸提供了额外的支持。对金星、地球和火星大气中惰性气体的比较表明，这些成分是由于行星内部的放气造成的。
The first gas chromatographic analysis of the lower atmosphere of Venus is reported. Three atmospheric samples were analyzed. The third of these samples showed carbon dioxide (96.4 percent), molecular nitrogen (3.41 percent), water vapor (0.135 percent), molecular oxygen [69.3 parts per million (ppm)], argon (18.6 ppm), neon (4.31 ppm), and sulfuir dioxide (186 ppm). The amounts of water vapor and sulfur dioxide detected are roughly compatible with the requirements of greenhouse models of the high surface temperature of Venus. The large positive gradient of sulfur dioxide, molecular oxygen, and water vapor from the clould tops to their bottoms, as implied by Earth-based observations and these resuilts, gives added support for the presence of major quantities of aqueous sulfuric acid in the clouds. A comparison of the inventory of inert gases found in the atmospheres of Venus, Earth, and Mars suggests that these components are due to outgassing from the planetary interiors.
