摘要 对稻谷裂纹产生机理的几种理论进行了比较分析,简述了测定热湿应力场物理参数、确定玻璃化转变温度以及含水率与应力场相互关系的实验方法,在此基础上,指出了结合损伤力学与玻璃化转变理论量化稻谷裂纹的产生的新方法。 Several theories for rice fissure are been compared and analysed. It also introducad the methods of measuring heat and moisture stress field physics parameter and glass transition temperature and the rela- tion between moisture content and stress field physics parameter. So that a new method describing rice fis- sure combined damage mechanics and glassy transition theory is introduced.
