Objective To use ANN to quantitatively predict the influence of the amount of HPMC and its internal viscosity on allopurinol release from HPMC sustained release tablets.
目的用人工神经网络模型定量的预测HPMC的量和其固有黏度对药物释放的影响。
Viscosity: viscosity is the crude oil in the flow caused by the internal frictional resistance, crude oil viscosity depends on temperature, pressure, dissolved gas and its chemical composition.
粘度：原油粘度是指原油在流动时所引起的内部摩擦阻力，原油粘度大小取决于温度、压力、溶解气量及其化学组成。
High viscosity pump can match the relief valve, when the pump and piping system overpressure, safety valve is opened, the formation of internal reflux, ensure the safety of the system.
高粘度泵可配安全阀，当泵或管路系统超压时，安全阀门打开，形成内部回流，保证系统安全。
