The main features of the secondary emission mass spectrometry probing of condensed systems containing compounds of biological significance at low temperatures are summarized. The possibilities of distinguishing mass spectra of the solid and liquid phases of simple organic compounds and water as the medium for bio-molecules, monitoring of phase transitions and nonequilibrium processes are illustrated. The peculiarities of a model of sputtering of metastable liquids are described. On the basis of the evaluation of these findings, an idea concerning the probable source of relatively large clusters of organic molecules and ions emerging on sputtering of the liquid phase of organic matter condensed on dust grains in space is proposed and discussed.

具有生物学意义的化合物的冷凝相环境的低温二次发射质谱研究

总结了在低温下对含有生物学意义的化合物的冷凝系统进行二次发射质谱探测的主要特征。说明了区分简单有机化合物和作为生物分子介质的水的固相和液相质谱，相变监测和非平衡过程的可能性。描述了亚稳液体溅射模型的特殊性。在对这些发现进行评估的基础上，提出并讨论了有关较大分子有机团簇和离子的可能来源的想法，这些簇团是由溅射在空间尘埃颗粒上凝结的有机物的液相溅射产生的。
