This thesis illustrates the main factors which influence the strengthened complex capabilities of aramid fiber Ⅲ, and more specifically introduces and discusses the factors that influence the aramid fiber Ⅲ itself.

Experimental study of basic properties of aramid Ⅲ fiber;

Study on the Colour Reaction of Fe(Ⅲ) with a new Colour Reagent 8Quinine Azo Quercetin LEI LiHong LEI ChunHua (Department of Analytical Chemistry,Hunan Medical College,Changsha 410006,P.

Based on the fact that Fe(Ⅲ)react with Vitamin B 6 to form the brown-yellow coordination compound,a simple and convenient method was established which can determine Vitamin B 6 in medicine by spectrophotometry and the rate of recovery can reach 96.
