title: [Studies relationship between powder characteristic of kinds of granules and their hygroscopicity].
abstract: OBJECTIVE
  To choose the granuling way for preparing granules that had low moisture-absorption characteristics.
  
  
  METHODS
  Granules were prepared by five ways, for studying the relationship between characteristics of powder and hygroscopicity were determined.
  
  
  RESULTS
  The prepared ways of granuling that had low hygroscopicity were dry granuling and secondary swinging granuling.
  
  
  CONCLUSIONS
  The hygroscopicity of granules can be explained by characteristics of powder, which are made in different granuling ways. The prepared ways of granuling that have low hygroscopicity are dry granuling and secondary swinging granuling.
