通过实证分析可以得出以下结论：（1）强化模型和BBAM在一定程度、一定条件内都能较好的刻画用户网络文献检索行为；（2）学习的发生是与特定的外部场景相联系的，在通常的非强外在约束下，有限理性个体进行随机决策时，其行为同时包含了有意识的理性计算和无意识的规则遵循；（3）在随机决策过程中，个体可能发生的认知进化应是有意识指导的结果，但收敛的方向却受到至少三个因素的影响：初始的信念状态、对反馈信号的主观判断能力、试错的次数。

That the electric elevator is that the call sign waits to work according to the outside as well as oneself controls law in fact, but call for is random , the electric elevator is that one people machine is each other dyadic in fact control system , the way the simple use sequential control or logic is controlled being that lift control system adopt the random logic therefore can not be satisfied with controlling call for's,controls.

实际上电梯是根据外部呼叫信号以及自身控制规律等运行的，而呼叫是随机的，电梯实际上是一个人机交互式的控制系统，单纯用顺序控制或逻辑控制是不能满足控制要求的，因此，电梯控制系统采用随机逻辑方式控制。

The relation between the parameter of ground motion and time is transformed into a pure random process with the amplitude varying with time.

By making a numerical analysis of the bistable stochastic dynamical systems, we find that the effect of an input sinusoidal signal is also a sinusoidal signal in the output, and the effect of the white noise is a Wiener process. When the system parameters are small enough, the coupling effect between the sinusoidal signal and the white noise can be largely weakened.

随机共振是双稳系统在周期信号和噪声的作用下表现出来的非线性现象，当系统的非线性与信号和噪声之间存在某种匹配时，通过对系统施加适当强度的噪声，可以提高系统对信号的响应，系统输出的信噪比对噪声强度表现出一峰状曲线[11] 。
