The type of shock reflection over 50o wedge model is of regular reflection. The angle between the incident and reflection shock is also being increased as the model surface roughness increased. The flow visualization results indicate that the speed of reflection shock becomes slower.

在50度的模型实验条件下则会产生正规反射,当增加表面粗糙度后会使得射震波与反射震波之夹角增大,由上述两者结果可以发现,其结果可归因於反射震波之移动速度减缓所致,因此增加表面粗糙度必然会使震波反射有减弱的情况发生。

First, the traffic flow time series chaotic feature is extracted by chaos theory. pretreatment for traffic flow time series, and the wavelet neural networks model was build by this. Second, the chaotic mechanism and the chaotic probability is described. Based on chaotic learning algorithm, and the wavelet neural networks fast learning algorithm of traffic flow time series is designed based on chaotic algorithm. Last, a single-step and multi-step prediction of traffic flow chaotic time series is researched by BP neural networks, wavelet neural networks and wavelet neural networks based on chaotic algorithm. The results showed that the wavelet neural networks predictive performance is better than the BP networks and the wavelet neural networks by the simulation results and root-mean-square value.

首先,通过混沌理论提取了交通流量时间序列的混沌特征,并在此基础上建立了小波神经网络交通流量时间序列模型;接着,阐述了混沌学习算法的混沌机理、混沌产生的概率,设计了基于混沌算法的小波神经网络交通流量混沌时间序列快速学习算法;最后利用交通流量混沌时间序列对BP网络、非混沌算法的小波神经网络以及基于混沌算法的小波神经网络进行了单步预测和多步预测,并对预测结果的仿真图和真实值与预测值的方均根进行了比较,结果表明基于混沌学习算法的小波神经网络的预测性能明显优于应用BP网络和非混沌算法的小波神经网络。

The simulation results show that the three models are all selfconsistent with electromagnetic field. Gauss law model tends to be affected by the width of the first cell and yield nonphysical oscillation. 1D diode model with reasonable discrete grid gets almost the same results as Child law model, but it needs to solve a transcendental equation, which would cost much time.
