Architecture description languages and their accompanying toolsets have been proposed as the answer. The XYZ/E is an executable linear temporal logic language. It can represent both dynamic and static semantics of systems. Basing on XYZ/E, the executable linar temporal logic language, we provide an architecture description language XYZ/ADL, which can represent both high-level abstract specification and the concrete implementation, thereby provides premise for the smooth transition from specification to implementation. And it can represent both the specification and the inner structure of a component under the unified logic framework, owing to the representability of the XYZ/E.

本项目研究旨在根据XYZ系统的特性，在时序逻辑语言XYZ/E的基础上，提出一种支持在XYZ系统中设计软件体系结构的描述语言XYZ/ADL，使之不仅能够对软件体系结构进行精确的形式化描述，而且为对其进行求精、验证、演化和分析提供基础，从而能在统一的时序逻辑框架下描述组件的规范和它的内部结构，并逐步过渡到最后的算法实现，从而能够支持软件开发设计的逐步求精全过程，把原有的两种支持软件开发的方法即支持模块化程序设计的方法和支持从规范到算法实现的逐步求精的方法有机地结合起来。

This essay has three difficulties: First, difficulty of conception foundation: how to grasp conception foundation, historical background and theory origin of positive economic paradigm and normative economic paradigm from a historical and philosophical perspective? Second, difficulty of formalization system: the viewpoints of positive economists and normative economists are very jumble, this paper tries to clear up the formers' theories, sums up and synthesizes various standpoints, and make it form systematism and standardization. Third, difficulty of combination in visual angle: combining economics and philosophy, resurvey some philosophy problems in economic research from the perspective of ontology, epistemology and methodology, thereby discover new problems, and make rigor argumentation toward it.

本文的难点：1、概念基础难点：如何从一种历史的、哲学的角度准确把握实证经济范式与规范经济范式的概念基础和变更的历史背景、理论渊源。2、形式化体系难点：实证经济学家与规范经济学家的观点非常混杂，本文试图理清前人的思路，总结和综合纷繁不一的观点，并使其体系化、规范化。3、视角结合点难点：将经济学与哲学有机地结合起来，从本体论、认识论、方法论的角度重新看待经济学研究中的一些哲学问题，从而发现新问题，并对其进行严密论证。

The second part briefly tries to retouch Tarski's theories and the method of definition of truth in formal language.

The thesis proceeds to discuss constraints required in accounting for the retroflex suffix-induced stem alternation and concludes that the complexities in stem alternation result from the interaction of the following constraints.

The asymptotical properties of KdV equation and KP equation exhibit the soliton behavior when some conditions are satisfied, and in some cases the parameter matrices describing the interaction between two solutions is quite simple. Two kinds of solutions of the second coupled equations of AKNS hierarchy are provided and applied to NLS equation. A systemical way of construction of special solutions is also tried for DS equation. Most of the results on a scalar equation can often be directly generalized to some matrix equation, and the difference between the ω in scalar form and ω in matrix form lies only in the replacement of vector p, q by matrices p, q.

对KdV方程和KP方程渐近性质的讨论显现出解在一定条件下的孤子特性，从而使得一些情形下，同类解的相互作用体现在参数矩阵上变的较简单；我们给出了AKNS方程的两类不同解，并约化到NLS；对DS方程，我们从另一个方面初步探讨了形式化推导矩阵方程特解的方法；把这些有关标量ω的结果推广到ω为矩阵上往往只要把p，q变为矩阵即可，进而可以再推广到方程组上。
