太阳内核产生的PP中微子被直接探测到（图）
太阳 核 PP中微子
2014/9/1
借助全球最敏感的中微子探测器，一支国际物理学家团队第一次向全世界报告，他们已经直接探测到了在太阳内核发生的、由“基础”质子—质子（PP）融合过程产生的中微子。
采用熔融挤出法制备了不同相容剂含量的PP/POE共混体系,测试了不同体系的脆韧转变温度、热性能和力学性能.结果表明,乙烯-丙烯多嵌段共聚物相容剂的加入降低了PP/POE共混物的脆韧转变温度,提高了共混物的韧性.AFM和STEM照片显示相容剂的加入减小了橡胶分散相的临界粒子间距,PP和POE在两相界面结合处相互扩散或渗透,实现了POE弹性体在PP树脂中合适的尺度分布以及良好的形态分散.当相容剂含量达...

2011/9/25
As a generalization of BCI-algebras with condition (S) and pseudo-BCK algebras with condition (pP), the notion of pseudo-BCI algebras with condition (pP) is introduced. An example of pseudo-BCI algebr...
