“把”字句的主要谓词受致使范畴与达成范畴的扩展,这为“把”字句提供了“致使—达成”这样的语义骨架。处置属于有意愿的致使,既跟致使范畴有关,又跟致事的意愿性有关。致使范畴除了选择有意愿的致事外,还会选择无意愿的致事,包括无意愿的施事、受事、活动及其非核心的参与者。包含无意愿致事的“把”字句都没有处置义。达成范畴也可以选择各种事件参与者充当役事与结果,结果论元表达状态、位置、属性与数量等方面的变化。主要谓词表达致使或达成的方式,这在“把”字句句法中不可或缺。

采用动态流变测试和扫描电子显微镜技术,考察高抗冲聚苯乙烯(HIPS)/高密度聚乙烯(HDPE)共混物的动态黏弹行为与相形态,对比1%(质量分数,下同)的纳米和微米CaCO_3对HIPS/HDPE(30/70)不相容共混物的增容效果。结果表明:当HDPE小于30%时,HIPS/HDPE共混物在低频区的复数黏度和储存模量均显示出明显的正偏差,而当HDPE大于30%时,则呈现负偏差;前者与HDPE和PB粒子间的相互作用相关,而后者归因于HDPE基体与PS分散相之间较弱的界面相互作用。当HIPS为基体时,HDPE分散相粒子呈现较宽的尺寸分布;而当HDPE为基体时,PS分散相呈现双模尺寸分布,对应于两种不同类型的PS分散相粒子的存在。1%的纳米CaCO_3对HIPS/HDPE(30/70)不相容共混体系起到了一定的增容效果,CaCO_3纳米粒子主要位于HIPS/HDPE相界面以及HDPE连续相内;而微米CaCO_3对该共混体系仅起到了增黏而非增容作用,CaCO_3微米粒子仅位于HDPE连续相内。
