1.
The effects of cold press pressure,sintering temperature and sintering time on oil reservation and oil retain were investigated;the model of predictive oil retain was designed by Back-Propagation Neural Network(BPNNN) and Radial Basis Function Neural Network(RBFNNN);training epochs and training goal of neural network were optimized with quasi-Newton method and Levenberg-Marquardt method.
以热塑性聚酰亚胺多孔材料制备工艺为研究对象,考察主要工艺参数(冷压压力、烧结温度及保温时间)对多孔材料关键指标(含油率和油保持率)的影响;采用反向传播神经网络(BPNN)和径向基神经网络(RBFNN),建立其油保持率预测模型,分别考察了Levenberg-Marquardt算法和拟牛顿算法优化网络模型的运算量和精度。
3)  retention

补充资料:持气率
分子式:
CAS号:

性质:气相占气液两相混合物的体积分率。空塔线速度是影响持气率的主要因素。在有大量液流循环的高液相流速下,持气率比较重要,当液相空塔流速小于3cm/s时,持气率的影响可忽略不计。
