中文摘要：

从数以万计的近地小行星（NEAs）中选择探测目标,是一项非常重要的工作.选择小行星时需要考虑的主要问题是：NEAs的轨道参数、自旋周期、大小、科学价值、表面特征以及到达NEAs的时间.本文采用排除法从众多近地小行星中确定候选者,并根据科学目标的要求确定最终探测目标.

英文摘要：

Selecting a suitable target for a space mission from huge number of discovered nearEarth asteroids（NEAs）has become a matter of immediate concern.The most important factors to consider in targets selection are：the global minimum total velocity increments（Delta-v）;travel time to and from the target;NEA orbital parameters,spin cycle,size,expected mineralogical composition;surface morphologies.Based on these factors and the scientific purpose, we identified about hundreds potential targets for the space mission through the exclusive method.The results provide a basic reference for the choice of next-generation mission targets.
