This paper is based on "Trilemma" which is induced from MF model. In order to overcome MF models inherent defects, this paper constructs a static model headed by government on choice of optimum exchange rate regime. Through the analysis of the model we can see that the choice of exchange rate regime is a dynamic process should be decided in real situation. No single exchange rate regime is right for all countries or at all time. Under certain condition intermediate regime may be the optimum one, but the possibility will decrease with the increase of international capital flow.

本文从蒙代尔——弗莱明模型精炼出的"三元悖论"出发，为了克服其内在的缺陷，构建了一个政府主导的静态最优汇率制度选择模型，模型分析表明：汇率制度选择是一个动态的相机决策过程，没有哪一种汇率制度对所有国家或某一国的所有时期都适合；在一定条件下，中间汇率制度可能是最优汇率制度，但是其可选择的区间随着资本流动程度的加大而缩小，最终最优汇率制度将内生的向两极分化。

Its dialogue is always together with the figures' actions. Also, the off-screen voice narrating means that the ongoing dialogues are confrounted with the inner monlogue, which expressed a deep phycological mind as well as a deep culture meaning.

同时，其人物对白往往简洁精炼，具有方言味和口语化特色，与影像艺术所追求的台词效果极为接近；而且，作者也很好地移用了画外音的影视技巧，通过外在对话与人物内心独白的对峙、外在对话与他人旁白的对峙，传达出人物的深层心理，也揭示了人性以及文化的深度，一箭双雕，耐人寻味。

The main methods to improve purification effects and the research orientation of aluminium fluxes are also introduced. It is pointed out that the popularization of home-produced equipment is important approach to increase level of purification for aluminum alloy trade, on the other hand, research on aluminium molten fluxes and purification mechanism should make progress in without polluter and multifunctional purificant.
