英文摘要:

      The process of whisker growth from solution system is dominated by many complicated phsical and chemical factors. The present paper discusses the formation of screw dislocation and the mechanism and kinetic law of whisker growth on the basis of elemntary stages of crystal growth. The influence of interface energy on the whisker shape was also briefly anal-ysed in thermodynmics.
