对流道的径向瞬态温度场分布进行差分求解，对流道轴向的温度分布运用能量平衡方程建立数学模型，并采用松弛迭代求解；最后，考虑流动和冷却过程的温度场分布，对流道径向和轴向温度场的计算结果进行了耦合分析，解决了长期以来只能依靠经验计算热流道温度场的局限。

The economics methodology has formed a whole battery of analytical framework and tool under the influence of scientific philosophy, which is characterized by logic positivism, negativism and historical materialism. The fundamental characteristics of the economics methodology are based on the axiomatization positive logic deductive method, which assumes the rational human being as its hypothetic premise. The most remarkable characteristic of the economics methodology is the general application of mathematics in economics and it is developing forward to the more accurate and magnificent system.

特别是在以逻辑实证主义、证伪主义和历史主义为代表的科学哲学的影响下，经济学的方法论已经发展出一整套的分析框架与工具，基本特征是建立在"理性人"假设基础上的公理化的实证的逻辑演绎方法，最突出的表现是数学在经济学中的广泛应用，并正在向着更为精密与恢弘的体系演进。

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.
