摘要

摘要 Dhajala 陨石（普通软玉，H3.8 型）的样本在一个特别设计的装置中，在 300 至 800°C 的温度范围内等温保存 90 分钟。用气相色谱仪研究了释放气体的成分和含量。检测到以下气体CO、CO2 和 H2O 的浓度为 10-60 µg/g 样品；此外，H2、CH4 和 H2S 的浓度为 0.3-2 µg/g。在每个固定温度下，脱气过程中的总氮含量随时间呈近似线性增长，从 1-2 微克/克增至 10-12 微克/克。根据对氮释放速率随温度变化的实验观察，得出的结论是相变的影响取决于矿物基质的渗透性。

Features of Nitrogen Degassing of Dhajala Chondrite (3.8)

Samples of the Dhajala meteorite (ordinary chondrite, type H3.8) were kept isothermically in a specially designed device in the temperature range from 300 to 800°C for 90 minutes. The composition and content of the released gases were studied on a gas chromatograph. The following were detected: CO, CO₂, and H₂O in concentrations of 10–60 µg/g of the sample; in addition, H₂, CH₄, and H₂S in concentrations of 0.3–2 µg/g. The total nitrogen content during degassing increased quasi-linearly over time from 1–2 to 10–12 µg/g at each fixed temperature. Based on experimental observations of the change in the rate of nitrogen release depending on temperature, it was concluded that the effect of phase transitions depends on the permeability of the mineral matrix.
