Mainly it discusses two problems: software instruments of viscosity and flash point using neural networks and operation optimization on the atmospheric and vacuum towers using NLJ method.

主要探讨了两个方面的问题：采用神经网络建立各个侧线粘度和闪点的软测量仪表以及采用NLJ方法实现常减压塔的操作优化。

The2 tables in QB2 are joined with nested loop join ( NLJ)

QB2中两个表用嵌套循环（NLJ）连接。

Based on system identification with recursive least squares method, the NLJ optimizing algorithm is used to tune the PID control parameters.

在运用递推最小二乘法在线辨识系统模型参数的基础上，采用NLJ方法（随机数直接搜索法）以ITAE（时间乘误差绝对积分）指标最优为目标对PID控制参数寻优整定。
