Especially, the dynamic neural network, which containing feedback process can directly and vividly reflect the dynamic nature of systems, thus it is attractive to use neural network technology to forecast the dynamic, non-linear exchange rate.In this paper, firstly we reviews and commentates the literatures of foreign exchange rate forecast, then introduces and analyzes from three perspectives, which are the basic theory of the exchange rate forecast, the main model and technical approach.

人工神经网络技术是一种非线性系统逼近和建模的有效工具，由于其具有良好的非线性映射能力及自适应、自学习和泛化能力，特别是包含反馈过程的动态神经网络能够更直接更生动地反映系统的动态特性，因而利用神经网络技术来对动态、非线性的汇率系统进行预测别具潜力。

Empirical results show that the ultimate controlling shareholders play a vital role in explaining analysts' forecast errors. Its proxies for controlling shareholder's stock hypothecating ratio, board seats controlled by controlling shareholder, president as well as CEO controlled by controlling shareholder all reveal significant direct or potential effects on analysts' forecast errors. Whereas, the ratio of cash flow right to stock voting right has a negative impact on forecast errors.

实证结果显示，控制股东概念之治理变数却大多呈现对分析师预测误差有著直接或潜在作用，作为控制股东持股质押率代理变数之董监持股质押率，与控制股东董事会席位比率对於分析师预测误差皆具显著正向影响；当公司发生损失时，董监持股质押率、现金流量权占控股权比率与分析师预测误差呈现显著负相关，控制股东的参与管理则对於分析师预测误差则呈现显著正向作用。

Forecast conclusion from prognosticating model abot river water quality may conflict with existing data of environmental monitoring,because it doesn't import existing data of forecast point In allusion to this condition, to import parameter of existing data may make forecast conclusion approach fact

河流水质预测模型使用的参数未引入预测断面现状监测结果，使预测结果可能与现状监测结果发生矛盾。针对这一情况，通过对预测模式的推导转化，在模型中引入污染源现状源强和预测断面现状监测浓度，将预测结果同现状监测结果联系起来，使预测结果更贴近实际
