研究者总结说：小脑幕上原始神经外胚瘤与成神经管细胞瘤的患者接受放疗和大剂量化疗后，脑白质损伤通常短期存在，并不产生症状。

Analyzed the structure and characteristics of WMLS . Pointed out that its optimizations generally are multi-objective problems , and safety , time and cost are the main decision objectives , among which the cost objective usually is less important than other objectives .

分析战时军事物流系统的结构和特点，指出其系统优化一般属于多目标决策问题，主要依据安全性、时效性和经济性等多个目标共同实施决策，且经济性只是次要的决策目标。

Pointed out that there is no strategy of WMLS that is absolutely better than others , different strategies are suitable to different battle objects , environments and situations , and the favorable factors and battle goals must be analyzed carefully to determine the military logistics strategy .

指出各种战时军事物流战略本身并无优劣之分，不同战略适用于不同的作战对象、作战环境和作战态势，战略抉择必须认真研究自身作战条件和作战目标。
