Our results first proved that the Tg relaxation of epoxy network is characteristic of standard linear solid with a single relaxation time which is independent of the molecular weight, stoichiometry and cure condition. 本实验和理论研究结果首次证明了环氧交联网Tg松弛过程具有单一松弛时间描述的线性标准固体的特征,与预聚体分子量、固化剂配比和固化条件无关。
It will provide the solid science theories basis for executing environmental law, confirming prevention and cure counterplan, evaluating its health risk and ecosystem risk. 为确定环境中TDI的安全量或容许量,评价该化合物的健康危险性和生态风险性提供了科学理论依据。
