塔顶压力 meaning in Chinese

tower top pressure

To improve the purity of carbon dioxide from the purifying column , a nonlinear model was established for describing the relationship between the carbon dioxide purity and the seven factors of feed purity , feed temperature , column top pressure , column top temperature , column reactor heating temperature , column reactor pressure and column reactor temperature built on the actual production data by using artificial neural network
摘要为提高提纯塔出口二氧化碳纯度，根据实际生产数据运用人工神经网络方法建立了出口二氧化碳纯度与进塔纯度、进塔温度、塔顶压力、塔顶温度、塔釜加热温度、塔釜压力、塔釜温度7个因素之间的非线性模型。
