From the point of view of stratagem, policy and measure, studied the countermeasures of Sino-America economy and trade in the new century in the third part of this paper.

同时，比较系统地从冷战意识和社会制度差异、思想文化和意识形态差异、双方所处国际地位的不同及美国国内政治斗争等几个方面，分析了中美经贸障碍产生的复杂性，揭示了中美经贸关系中经济与政治互动的多向性和国家关系的复合多重性，为新世纪确立发展中美经贸关系的对策找到真正切入点提供理论支撑。

The results showed that M1 and M2 present the enantiotropic nematic phase ,M3 presents the nematic phase with SA,SC and SB smectic phases and M4 presents the nematic phase with SA,SC and SB monotropic phases.

研究表明，单体M1和M2呈现互变向列相，M3呈现向列相和近晶A相、近晶C相和近晶B相，M4呈现向列相和单变SA相、SC相和SB相；聚合物P1和P2呈现向列相，P3和P4呈现SA相和向列相。

In addition, molecular orientation behaviors induced by shearing, electric field and magnetic field were investigated. The space group of the monomers A3EO7 and A9EO7 were determined as P2〓2〓2 and P112/m by means of electron diffraction and X-ray diffraction. Liquid crystalline properties of the monomer and the polymer were studied using DSC, variable X-ray diffraction, TEM and polarized optical microscope. Both monomers exhibit monotropic liquid crystalline behavior, and they also give a metastable phase on the cooling process. The polymer PA9EO7 shows enantiotropic liquid crystalline properties. Thus the rigid polymer backbone is not a fatal defect that completely distorts the packing arrangement of the mesogenic moiety in the side chain liquid crystalline polyacetylene.

结合电子衍射倾转方法和粉末X射线衍射技术，确定了两个液晶小分子A3EO7和A9EO7的晶胞参数和空间群，采用Cerius〓模拟软件，运用分子模拟的方法给出了小分子在晶胞中的排列方式；利用DSC、变温X射线衍射技术和透射电子显微镜研究了小分子和聚合物的液晶态，单体A3EO7和A9EO7表现出单向液晶性质，并且在降温过程中都表现出一个亚稳液晶相或亚稳结晶相，聚合物PA9EO7具有双向液晶性；采用偏光显微镜和X射线平板照相技术，研究了剪切和电场对聚合物分子取向的影响，在不同的液晶态，剪切作用对聚合物PA9EO7具有不同的诱导取向结果，直流电场可以诱导聚合物联苯液晶基元沿施加电场方向取向。

The researches show that polymer PM5MPP and copolymer M5MPP/MMEANB are enantiotropic liquid crystalline polymers, but polymer PMMEANB has no liquid crystalline properties....

结果表明，均聚物PM 5MPP及共聚物(M 5MPP/MMEANB)属双向液晶高分子；PMMEANB属于非晶性高分子。证实了分子间吸电子与给电子基团相互作用有利于提高液晶高分子热稳定性，共聚物(M 5MPP/MMEANB)具有较宽的液晶相温度范围。
