说明：  D-S证据理论的融合思想主要体现在待识别对象的多个证据的基本概率分配函数通过某种规则融合在一起，求出所有证据的总支持程度，证据理论给出了多源数据的组合规则
(The fusion theory of D-S evidence theory is mainly reflected in the basic probability distribution function of multiple evidences of the identified objects, and the total support degree of all evidence is obtained by combining certain rules. Evidence theory gives the combination rule of multi-source data.)
