thermosenescence
- 具有优良的热老化性能。
It has excellent thermal aging performance. - 通过其他实验（如红外光谱、测量密度、测量折射率、测量体积电阻率）的相互对比，基本上肯定了有机玻璃“极性基团断裂”的热老化模型。
In order to explain the phenmena, two supposes of "hole" and " polargroup rupture" are proposed, according to the tests of IR, density, refractive index, conductor volume resistivity, the aging model of PMMA is confirmed likely. - 利用红外光谱和凝胶色谱等技术考察了胜利100B和韩国70两种道路沥青热老化后族组成、羰基与亚砜官能团以及相对分子质量分布的变化。
