Abstract : because of the characteristics of straws , the reinforced preparation and displacement cooking for deep delignification caused a better result in yield , strength , colour , and consumptions . the drainage of cooking can be recovered or comprehensively utilized , so a new idea of straw pulping with high quality and low consumptions has been established 文摘:从禾草原料的特性出发，采用强化备料，置换蒸煮，对草浆进行深度脱除木素，可以提高成浆的得率、强度和原浆的白度.对排出物进行碱回收和综合利用，节能降耗显著，为生产高质量、低消耗的草浆开拓了新的途径
Another feature in technical innovation is to update the old product of the company , which has got good effect . through upgrading electrostatic precipitator for black liquor boiler , which is the key equipment at the stage of combustion in the system of papermaking alkali recovery , its availability and reliability have been improved in great way 对老产品的更新，是公司技术创新的另一个特点，起到了相当好的实际效果，造纸黑液锅炉电除尘器是造纸碱回收系统燃烧工段关键设备，通过不断的技术更新，其适应性和可靠性得到了极大的提高。
Simulation results show the effectiveness of the algorithm . based on the integration of rough set and neural networks , a rough neural network based on predictive model control strategy for alkali recovery boiler control is developed . the framework of alkali recovery dedicated control system is introduced in chapter 5 , including system hardware frame and software design and basic functions of system 3 )针对碱回收蒸发工段具有强耦合、大时滞的特性，通过分析传统解耦算法的不足，提出了蒸发工段神经网络解耦控制方案，通过仿真证明方法的有效性；同时通过集成粗糙集和神经网络方法，提出了基于粗糙集的神经网络预测模型控制方案，并应用到碱回收炉的控制当中。
