借助傅里叶红外光谱和核磁共振氢谱等分析手段研究了双酚A聚碳酸酯(BPA-PC)在高温剪切混炼过程中的热降解行为,考察了不同抗氧剂对提高PC热稳定性的作用,探讨了PC的热降解黄变机理.结果表明,亚磷酸酯抗氧剂通过抑制碳酸酯键的断链反应,能有效提高PC的色泽稳定性.受阻酚抗氧剂上的酚羟基不利于碳酸酯键的热稳定,易导致其发生断链反应,但却有助于异亚丙基键的热稳定化.此外,探讨了不同降解产物对PC色泽的影响,对比发现,酮类降解产物上的羰基共轭结构可能是引发PC黄变的主要发色基团.

通过对广州市南沙地区大量软土物理力学试验和微结构分析,获取了40组软土试样的物理力学性质指标和微观结构参数。综合运用灰色关联分析的数据分析能力和人工神经网络的非线性映射功能,建立了软土物理力学性质指标与微结构参数的灰色关联-径向基神经网络模型。该模型利用灰色关联分析方法对数据进行预处理,提取重要因子作为网络的输入,而径向基神经网络充分利用样本数据信息,自适应确定隐含层节点个数、径向基函数中心、宽度以及网络的权系数。克服了传统RBF网络隐层节点数为样本个数,当数据较多时导致网络结构庞大、学习速度慢的缺点。通过模型A和模型B的实例研究表明,该方法简化了网络结构,提高了训练速度和预测精度,为软土物理力学性质与微结构参数关系的定量研究提供了一条有效途径。
