金庸较为重视冰蚕的药用功能,'药用'的深层情结构成了金庸小说重要的母题动机。唐人心目中的冰蚕,带有海洋文化仙道气息,宋代笔记关于冰蚕的明确记载,仅提到出自西域、云南,足以显得遥远而新奇。金庸先生与香港、海外和大陆南方众多读者一样,对北国雪地风光,有着一种好奇和向往,冰蚕实际上属于作者的一种'意识形态形象',而非西域实物,其更加衬托出北国冰雪严寒地带及其'异域风情'作为'意识形态形象'的可信度,强化南国人们对其想像联想。这一与雪景酷寒相联系的物象,便于构筑奇绝诡异的'异域风光',为作品的形象和情节构设出较大的审美张力。

以沁水盆地等煤样品煤孔隙分析和等温吸附试验研究为基础,通过煤吸附气体动力学过程和吸附理论模型分析,从物理化学层面对煤吸附气体的固气作用机理进行了深入探讨。认为:煤吸附气体动力学过程包括渗流阶段、表面扩散阶段、体扩散阶段和吸着阶段;煤—煤层气吸附体系的吸附力和吸附能决定了不同煤级煤对不同气体吸附量的大小;扩散对煤吸附气体的动力学过程有重要控制作用;煤—甲烷吸附体系应存在多元化的吸附模型,当压力8～10MPa以上时,Langmuir单分子层吸附模型的适应性受到限制,凝聚—吸附孔隙发育和气体凝聚是制约Langmuir单分子层吸附模型的主要原因。
