The palaeo-forest vestige has been found for the first time on the sea floor of Shenhuwan Gulf, Jinjiang County, Fujian Province (N24°38′, E118°39′) during my seismic investigation in July, 1986.

关键词 Thermotropic LIQUID CRYSTALLINE polymer Poly(aryl ether ketone) Shear flow Molecular ori entation 分类号:O6 文献标识码:A 文章编号:1005-9040(2001)-02-233-04 Polarized optical microscopes(POM) are commonly used to identify LIQUID CRYSTALLINE tex tures. However it is often found problematic to employ this technique in investigating the MESOPHASE transition of polymeric materials DUE to their higher viscosities. RHEOLOGICAL mea surements at this juncture could provide us with valuable information about the MESOPHASE transition of LIQUID CRYSTALLINE . Accordingly there have been some RHEOLOGICAL in vestigations reported on thermotropic LIQUID CRYSTALLINE polymers(TLCPs) DUE to the high sen sitivity of their RHEOLOGICAL response to the morphological variation of the polymers[2~5].Introduction Polarized optical microscopes(POM) are commonly used to identify LIQUID CRYSTALLINE tex tures.
