空间生命科学研究日益重要,但是由于受到稀少空间实验机会和高昂实验成本等条件制约,目前对空间环境的地面模拟技术要求更加迫切.在较系统地分析现有微重力环境模拟技术的技术特点和适用范围的基础上,结合未来多因素耦合研究的发展趋势,提出了采用激光光阱技术模拟微重力环境的建议.激光光阱操纵生物细胞的非接触性、光穿透性和定位性有助于获得较好的模拟效果.激光光阱技术与单细胞定点单离子辐射技术良好的相容性和互补性有助于开展微重力与辐射的耦合影响研究.

The study of space biology becomes significant and requires the advanced technologies for stimulating space environment considering the rare opportunity and the high costs of space experiments. In this article, the characteristics and applications of the existing technologies for stimulating the microgravity environment are systematically analyzed. Based on the research tendency of the coupling effects of multi-factors, laser trap is proposed to be the next generation technology for the simulation. This technology has the great advantages for manipulating cells without contact, manipulating intra-cell particles and fixing cell position, which is valuable for producing the good simulation effect. The well compatibility and complementation between the technologies of laser trap and the single ion radiation will be very useful for the study of coupling effects of the microgravity and radiation.
