A hybrid model of short-term load forecasting based on chaotic theory, correlation and neural networks is presented in this paper. Firstly, reconstruct attractors in phase spaces using chaotic theory, Secondly fit the attractor's evolvement using BP neural networks, because selecting neural network's input training data using Euclid distance and correlation, improve neural network's associative memory and ratiocinative ability, can better fit the attractor's evolvement.
提出一种将混沌理论、关联度和神经网络相结合的短期负荷预测模型,首先利用混沌理论重构负荷时间序列的相空间吸引子,然后用BP 神经网络来拟合空间吸引子的演化,由于使用空间欧氏距离和关联度联合来选取神经网络的训练样本,这样就提高了神经网络对负荷序列混沌特性的联想和泛化推理能力,能够更好的拟合吸引子的演化。

In this paper, the basic theory and work principle of cellular automata were introduced concisely. The influence of strain-rate and temperature on the number of nucleation and the mean size of R-grain, as well as the influence of cooling on ultimate microstructure of blade after forging finished off were considered. The microstructure evolution was simulated successful based on the DEFORM-3D. The simulated results agree well with growth kinetics of dynamic recrystallization of classical theory and physical experiment.

It was proposed in the 1960's and developed rapidly in the 1990's. However, some theory problems, for example, the fluid dynamics and mass transfer during the filling up period which could not be dealt with in conventional distillation theories has been remained unstudied. And the simulation and mathematical models have to be made based on some assumptions, which are different from the actual situation obviously. Therefore the further development of DACO was restrained in the past years.
该操作方法自20世纪60年代提出,90年代以来得到了迅速发展,但众多学者的研究基本上集中在优化操作及其与传统恒回流法的比较,而许多重要的基本理论问题至今缺乏研究,特别是传统精馏理论无法涉及的塔内无回流充液阶段的流体力学和传质问题一直没有得到很好解决,导致了动态累积循环操作法的数学模型和模拟计算只能以与塔内真实状况相差很大的简化假设为基础,这严重地阻碍着动态累积循环操作法的进一步发展。

The enhanced emission yields of secondary ions induced by Si2 clusters at the low energies are clearly seen and attributed to the vicinage effect of the nuclear collision processes of cluster constituents and the secondary ion emissions are still dominated by electronic stopping processes at high energies.
实验结果显示,在以上的生物样品中,MeV能量离子的能量损失值和TRIM程序模拟的结果相吻合,但是透射离子的能量离散值却与TRIM程序模拟结果有很大的不同。结合生物样品的结构不均匀的特性,对Bohr能量离散理论进行了修正,并发现修正后的Bohr能量离散理论计算结果与实验值符合得很好。
