针对大时滞时变对象，把Smith补偿控制原理和PID参数的自适应调整方法结合起来，提出了基于BP神经网络整定Smith PID控制算法，即在Smith预估补偿控制系统中，利用BP神经网络在线自学习整定PID参数，使PID参数实现最佳的非线性组合，以适应对象特性的变化，从而克服了常规PID算法不适应大时滞系统控制和常规Smith算法过于依赖模型精度的缺陷。

Couples are often blind to key differences between them, not just in the first heady days of romance, but right up until the moment at which those differences become a real and perhaps insurmountable problem,' said Terry Prendergast, the charity's chief executive.

"夫妇通常看不到他们之间的关键差别，这不仅发生在浪漫开始的那段时间里，甚至在那些差别已经成为事实、或者已经成为了不可克服的问题的时候，他们仍然看不到，"该慈善机构的总裁Terry Prendergast说。

Considering the effect of the angle of internal friction on the inclination of sliding plane of soils behind retaining wall, circular and catenary, the two shapes of minor principal stress arch are theoretically analyzed. According to the shapes of minor principal stress arch, the coefficients of earth pressure corresponding to different angle of internal friction and that of wall friction are gained.
