At last, the VNNTF networks learning algorithm is designed, and a single-step and multi-step prediction of traffic flow chaotic times series is researched by VNNTF networks, the VNNTF networks predictive performance is better than the BP networks and Volterra functional model by the simulation results and root-mean-square value.

最后，设计了VNNTF网络学习算法，利用VNNTF网络对交通流量混沌时间序列进行了单步和多步预测，与BP网络和Volterra模型的预测结果比较，取得了相当好的预测效果。

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。

I am not a ropedancer. I advance one step by step by another, but I still have a lot of idle time to deal with .

我不是走钢索的艺人，只想一步步地向前，但我却不知如何打发那剩余的时光。

Route march speed was reduced from 7.5 to 5 km/h, running occurred on softer surfaces, individual step length was promoted instead of marching in step, march and run formations were more widely spaced, and interval-running training replaced traditional middle-distance runs.

路径游行速度从 7.5 到 5 公里/h 被减少，赛跑在较软性的表面上发生了，个体步骤长度被促进而非在步骤，游行和奔跑中游行形成更广泛被隔开，和跑间隔的训练代替了传统的中央-距离奔跑。

In one aspect, the present invention comprises a synthetic route in which step precedes step.

But as the programs went on ,we learnt to walk the parade step and the route step which you need physical coordination ,or you'll look strange when you ara walking ,not very bad except not in tune with others walking around you And we were going to take part in review before the general ,however only 50%of us could have the chance to attend it as a square matrix ,the others will only be the spectators ,to tell the truth I was almost one of the spectators ,but as a guy who lack of compatibility 'cause my muscles were too nervous which made the drillmasters hesitate ,my drillmaster told the other one that that guy was the most hardworking one .

但是随着训练的进行，我们又学习了走便步和正步，这都需要身体的协调性，否则你会看起来有一点奇怪，不能算错，就是和周围的人不协调，而我们要去参加阅兵式接受首长的检验，然而只有一半的人可以作为一个方阵参加，其他的人就只能作为观众了，说实在的我几乎已经是观众中的一个了，但是作为一个所谓的身体不协调者，主要是因为我的肌肉太过于紧张导致的，我让教官们感觉到很犹豫不决，但是我的教官对另外一个说，这个孩子训练是最刻苦的，对方说，是的，我知道，你说呢？
