摘　　要：采用小角X射线散射法(SAXS)研究了HF,HCl,H_2SO_4和HAC分别对含水磷脂酰乙醇胺(PE)液晶结构的影响。通过研究发现,HF有使PE液晶态变成C相的机理,HCl有使PE液晶态变成LH相的机理,H_2SO_4有使PE液晶态变成L相的机理。而HAC则有使PE液晶态经过L相转变成LH相的机理。This paper presents the results of inves'igation on the influence of HF, HC1, H2SO4 and HAC on the liquid crystal structure of phosph tidyle-thandamine(PE) by means of the me-thod of small angle x-ray scattering method. The experiment shows that: HF exhibits the me-chanism that makes PE liquid crystal sta'e to transform into C phase; HC1 exhibits the me-chanism of transforming into LH phase; H2SO4 results in La phase; and HAC results in LU phase via L0 phase.
