1) shrinking ability
缩膨性
1.
It was shown that besides of PDMD in 50 g/L solution and DMDAAC in 20 and 50 g/L solution these QASs had no shrinking ability and concluded that a shrinkage chemicl should contain no nonionic polar functionality(es) such as hydroxyl and ether linkage,be of medium molar mass,and have cationic functionality(es) in side group(s) or in heterocycle(s) in chain.
除DMDAAC聚合物PDMD(50 g/L溶液)和DMDAAC(20和50 g/L)外,这8种季铵盐均无缩膨性,认为具缩膨性的季铵盐分子中不应含非离子极性基因如羟基和醚基,阳离子应在支链或杂环上,且相对分子质量适当。
2) expansibility and contractibility
膨胀收缩性
3) swelling/shrinking properties
膨胀-收缩特性
4) dilatational compressibility
膨胀可压缩性
5) dilation
[英][dai'leiʃən] [美][daɪ'leʃən]
膨缩
6) swelling shrinkage ratio
缩膨率
