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。

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.

To apply ARIMA models the time series needs to be stationary. A stationary time series is one whose statistical properties such as mean, variance and autocorrelation are constant over time. If the initial time series is not stationary it may be that some function of the time series, e.g. taking the differences between successive values, is stationary.
