半结晶期 meaning in English

half-crystallization time

The crystallization property were investigated by dsc . it was shown that the joining of ommt has a little effect on melting point of pp , the crystallization temperature of pp was improved obviously and the degree of crystallinity was increased ; through studying on kinetics of isothermal crystallization , the constant ( k ) of crystallization speed and crystallization speed ( g1 / 2 ) were lowered with rising of crystallization temperature ; half period of crystallizations and ( tp ) were delay with rising of crystallization temperature
Dsc研究结晶行为表明：有机蒙脱土的加入对pp熔点的影响不大，使pp的结晶温度明显提高，结晶度增大；通过等温结晶动力学的研究，结晶速率常数k和结晶速率g _ ( 1 2 )均随结晶温度的升高而降低；半结晶期t _ ( 1 2 )和t _ p都随结晶温度的升高而延长。
