针对MS密封胶常温拉伸强度，加速老化后的断裂伸长率、拉伸强度、60%定伸模量及最大强度伸长率是影响模型预测的关键变量。其中，加速后断裂伸长率、拉伸强度均与预测强度呈正相关，指标越大，模型越倾向于高强度预测;而加速60%模量与最大强度伸长率则与预测强度呈负相关，指标越低，模型输出的强度预测值越高。

针对MS密封胶常温最大强度伸长率，加速老化后的断裂伸长率、最大强度伸长率、60%定伸模量及100%定伸模量对模型预测的影响最为突出。数据显示，加速后断裂伸长率、最大强度伸长率及60%定伸模量均与预测伸长率呈正相关，指标越高，模型越倾向于高伸长率预测;与之相反，加速100%定伸模量与预测伸长率呈负相关，该指标越高，模型输出的伸长率预测值越低。

机器学习模型的构建高度依赖大规模数据驱动。基于SHAP特征归因分析可知，模型能够依据两类MS密封胶的关键物理化学参数实现预测推理。具体而言，加速老化后的特征指标表征了MS密封胶内部交联结构的稳定性，拉伸强度与模量则反映其分子链间的内聚强度而断裂伸长率体现了交联网络的延展性及分子链的柔顺性。

由图还可知:针对低模量耐候MS密封胶，模型将加速老化后的低拉伸强度、高断裂伸长率及低模量特征相关联，实现了对常温模量的精准预测;而对于MS密封胶等高强度MS密封胶，模型则将高拉伸强度与低断裂伸长率特征藕合，进而输出相应的预测结果。

综上，XGBoost模型经对两类MS密封胶性能数据的深度学习，有效识别了耐候胶的低模量特性及MS密封胶的高强度特征，证实其能够通过解析MS密封胶内部分子交联网络结构及其延展性特征，实现对常温力学性能的高精度预测。http://www.sdyuantai.com/
