在本文中，提出以微中浪轧制策略补偿冷却不均造成的板形不良，从理论上分析了微中浪轧制策略的可行性，并给出不同规格带钢的最佳设定值，使微中浪轧制设定由目前依靠经验的尝试性阶段，上升到根据理论计算定量化的描述阶段，对于指导热轧带钢的生产具有重要的意义和实用价值。

Although the panel logit models verify the effects of the explanatory variables consistently with the theory, the prediction accuracy is not as good as that of neuro fuzzy. In addition to the better out-sample prediction accuracy, neuro fuzzy also provides a more detailed and complicated relationship among the variables through the rule base mid 3-dimension graphics, which could be used for further theory development or modification Overall, the banking crises ca be predictable; however, each country needs different forecasting model. The mapping between the forecasting model mid data set characteristics ca be further developed for the future research.

实证结果显示，虽然Panel Logit之固定效果与随机效果模型皆验证了过去理论上各变数对银行危机之影响方向，但整体而言，其预测准确度并不比类神经模糊好；而类神经模糊除了提供更准确的样本外预测之外，其所建构的规则库与3D图提供较以往更为细腻的变数关系，此关系可作为未来理论发展之基础；整体而言银行危机可以被有效的预测，然而单一国家的预测结果显示不同的国家适用不同的预测工具，没有一项工具能够适用於所有的国家；而资料集属性与预测工具之对应关系可作为未来之研究方向。

To solve it effectively has not only great theoretical function, but also very important pragmatic value in the filed of calculable theory.

有效的解决它，在可计算理论上具有重要的理论意义，同时也具有重要的实际应用价值。

In theory,based on the theory of actio libera in causa,we can conclude that the casual acts can not influence the hit-and-run behaviors;in practice,case review should be based on proofs,as well as dependence on the development of related judicial authentication.

在理论上以原因自由行为理论为基础，可以得出原因行为对逃逸行为已失去支配力；在实践方面，审查案件要以证据为基础，还要依赖于相关司法鉴定的发展。

The different distributions of electrical fields produced by circular coil and butterfly-shaped coils are calculated. The results are compared with those of other researches. And some differences in theory are analyzed.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
