The shearing instrument of laser light-scattering, as the credible research technique at present in the world, is applied for study on the form and micro-structure of polymers in the process of manufacture. The results can provide the experimental and theoretical evidence for designing and processing the multiphase polymer materials.The shearing instrument have been exploited JQY-0 type completed by the research group. The aim of this paper is to develop a new type of shearing cell which includes the contro...
