The purpose of this research is to discuss the decision of negotiation types and processes. The conponents of the decision-making of each transaction include "the counterpart" and "the deal". The Potential Value of Social Transaction and The Potential Value of Economic Transaction can distinguish between the "quasi-economic man" and the "quasi-social man", two different types of psychological construction. This research makes a point of dyad according to a quasi-economic man and a quasi-social man which can distinguish among three different dyadic decisions of negotiation types:the dyadic decision of negotiation type between a quasi-economic man and a quasi-economic man, the dyadic decision of negotiation type between a quasi-social man and a quasi-social man, and the dyadic decision of negotiation type between a quasi-economic man and a quasi-social man.

摘要 本研究旨在探讨谈判决策类型与过程之研究，交易双方在谈判时不只会考虑交易事物「事」，也会考虑交易对象「人」，本研究以社会交易潜在价值和经济交易潜在价值所表现出的交易权衡模式，把个人区分为准经济人与准社会人两种不同类型的人，本研究旨在分析谈判双方如何讨价还价达成交易的过程，特别重视二位体的观念，根据准经济人决策权衡模式与准社会人决策权衡模式的组合区分出准经济人与准经济人的二位体谈判决策类型（A-1类型）；准社会人与准社会人的二位体谈判决策类型（A-2类型）；准经济人与准社会人二位体谈判决策类型等三种不同的类型。

Our results improve the former results. For periodic Jacobi matrix, some new spectral properties of periodic Jacobi matrix are given by studying the relationship of the eigenvalues of periodic Jacobi matrix and its n—1 principal submatrix. Applying these spectral properties, we present a necessary and sufficient condition for the solvability of an inverse problem of periodic Jacobi matrices and discuss the number and the relationship of its solutions. Furthermore, we propose a new algorithm to construct its solution and compare it with the former algorithms. As this inverse problem of periodic Jacobi matrix usually has multiple solutions as many other eigenvalue inverse problems, we study the uniqueness of this problem. And a necessary and sufficient condition is given to ensure its uniqueness, under which an algorithm is presented and the stability analysis is also given. Finally, we put forward a new inverse problem for periodic Jacobi matrix which has not been solved.

The results of 3-D numerical modeling of the transversely isotropic media with horizontal symmetry axis and the orthorhombic symmetry media showed that quasi P wave,quasi-SV wave and quasi-SH wave occurred during elastic wave propagation in 3-D anisotropic media. Meanwhile, the special phenomena such as the S wave splitting, the blind zone of S wave splitting and quasi-SV wave-front triplication were clearly observed. In addition, the elastic wave-fronts are spatially changed, and the coupled relations among the quasi-P wave,quasi-SV wave and quasiSH wave in 3-D anisotropic media are very complex.

The instability originated in the upper R_B-like convection zone develops to larger region with the increase of Grashof number, and the number of non-axi-symmetric circulations decreases. When Grashof number exceeds another critical value, cooling air may invade the cavity and flow toward the shroud, the circulations decrease to one pair occupying the whole cavity in radial, thus these two zones are merged into one. The core structures in the cavity rotate against the disks, while the structures keep no change at the case of periodic oscillatory flow. With the Grashof number rises, the flow undergoes stable, periodic, periodic with cool air invading, quasi-periodic and ultimately to chaos.

离心浮升力是造成非等温轴向通流旋转盘腔内流动不稳定的主要因素，而哥氏力的存在加剧了流动不稳定性，导致流场失稳提前发生，而且在哥氏力的作用下流线发生偏转，盘腔内r-θ面出现了旋向相反的对涡，流动结构更加复杂化；随离心浮升力的继续增加，r-θ面的对涡减少，当其超过某一临界值后部分冷流体侵入盘腔，对涡减少至一对，而且沿径向充满整个盘腔；此后随离心浮升力的增加对涡的数量不再变化；r-θ面的对涡相对于盘面周向移动，但是形状基本保持不变。
