EFFECT OF ORIENTATION ON RADIAL DISSTRIBUTION FUNCTION

The errors may be introduced in the process of measurement and evaluation forpreparing radial distribution function(RDF),They will cause the error distortionthat RDF can be partly upset.RDF method is based on structual isotropy of amor-phous materials,however,a structural anisotropy,i.e orientation,has been foundin amorphous polymeric,inorganic and metallic materials.The orientation will gre-atly affect RDF,and will lead to a new distortion that RDF may be wholly upset.Obvirously,if it is not given due regard,a misinterpretation on RDF can occur.The feature of the so-called orientation distortion is discussed in the present paper.
