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.
首次对金星底层大气进行了气相色谱分析。分析了三个大气样本。其中第三个样本显示二氧化碳（96.4%）、分子氮（3.41%）、水蒸气（0.135%）、分子氧[69.3 百万分率（ppm）]、氩（18.6 ppm）、氖（4.31 ppm）和二氧化硫（186 ppm）。检测到的水蒸气和二氧化硫含量与金星高表面温度温室模型的要求大致相符。根据地球观测和这些结果推断，从云顶到底部，二氧化硫、分子氧和水蒸气的巨大正梯度为云层中存在大量含水硫酸提供了更多支持。金星、地球和火星大气中惰性气体含量的比较表明，这些成分是由于行星内部的脱气作用而产生的。
