| 摘 要： | A great quartity of cosmic dust(spherules) was found in deep-sea sediments during May to July,1983manganese nodule investigations by the R/V“XIANGYANGHONG 16”in the area 7°-11°N,167°-178°Win the Pacific.Comprehensive study of the cosmic dust and determination with Laser Raman MolecularMicroprobe(LRMM) of the molecules in it showed that besides Fe-Fe,Fe~(3+)-O,Fe-Ni,Al-O,Fe-Obr-Si and Si-Onb,it also contained the organic molecules C-H-O and C-H-S-O,various no fixed form molecules of C,CH_2,CH_3 and volatile molecules CO_2,H_2O,OH~- and H_2S,etc…The study result has very important applications for exploring the origin of interplanetary dust parti-cles and life material.

| Abstract: | A great quantity of cosmic dust (spherules) was found in deep-sea sediments during May to July, 1983 manganese nodule investigations
by theR/V “XIANG YANGHONG 16” in the area 7°–11° N, 167°–178°W in the Pacific. Comprehensive study of the cosmic dust and determination with Laser Raman
Molecular Microprobe (LRMM) of the molecules in it showed that besides Fe−Fe, Fe3+−O, Fe−Ni, Al−O, Fe−Obr−Si and S−Onb, it also contained the organic molecules C−H−O and C−H−S−O, various no fixed form molecules
of C, CH2, CH3 and volatile molecules CO2, H2O, OH− and H2S, etc …
The study result has very important applications for exploring the origin of interplanetary dust particles and life material.
