1) PS-irresolute mapping
PS-不定映射
1.
In this paper,based on the PS-irresolute mapping introduced by the author,the strong PS-irresolute mapping in L-spaces is intoduced by means of pre-semiopen L-sets and it is proved that the strong PS-irresolute mapping is a PS-irresolute mapping,but the inverse is not true.

补充资料：PPO/PS blend
分子式：
CAS号：
性质：聚苯醚与聚苯乙烯共混可以在不过分损失PPO的耐热性的前提下，改善其加工流动性并降低成本，而且还可以解决PPO易开裂的问题。组分为50/50时动态黏弹谱上损耗模量E′值显示出最明显的宽化，可以认为两种材料发生了广泛的但并不是完全的混合。主要用于汽车工业、代替黄铜管等；还用于制造机器外套、电视机零件、医疗器械等。
