首先，由于现实经济中涉及的因素众多，相互关系复杂，给数学方法的运用带来了一定困难；其次，传统方法没有很好地解决经济系统的层次性结构问题，因此，无法对不同层次的特性差异给予一个整体性的解释，也就产生了宏观、微观相互脱节的理论体系上的缺陷；再次，传统经济理论对现实经济普遍存在的信息不完备与不确定性尚不能给予系统的解释；最后，传统经济中以观测数据为基础的经验主义的研究方法，无法深入了解经济的微观运行过程，从而降低了理论对现实的解释与预测能力。

The priorities are the diversification characteristics of each targetin the subsequent water flooding. According to diversification characteristics of these targets,the paper studies how the heterogeneousness, water flooded condition, interconnectingcondition of zone;key measures injector parameters affect these targets from polymer floodingmechanism. Based on influence equations, production target prediction models are built usingHall curve theory, relative permeability curve, relations of water saturation and relativepermeability and material balance equation. Parameters of models are calculated by the way ofcomputer program and so that a simple, fast way have been gained to predict production targetof polymer subsequent flooding.

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。
