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 membrane isolation pumps is one kind of hydromass transportation hydraulic system,can reduce the cartage expense greatly,but indirectly brings the huge social efficiency,safe reliable,the work rate is high,may not stop nearly carries on the whole year to transport,does not have the material to lose nearly,the easy automatic control,to be advantageous for the maintenance management The hydraulic pressure diaphragm pump is one kind of fill domestic diaphragm pump which we develops in high-pressured,the small curr ent capacity pulp transportation aspect blank pumps plants,it and the common diaphragm pump main difference is:Has substituted for the crank connecting rod,the reduction gear using the hydraulic pump and so on aseries of equipments direct drive piston motion,this causes its structure is greatly the simplification,the cost drops greatly;When at the same time also requests the piston the commutation confidential assurance extremely accurately,but must realize this point theoretically and all has the very great difficulty in fact.

膜隔离泵就是一种浆体输送的液压系统，能大大降低运输费用，可间接带来巨大的社会效益，安全可靠，作业率高，几乎可不停地进行全年输送，几乎没有物料损耗，易于自动控制，便于维护管理。液压隔膜泵是我们开发的一种填补国内隔膜泵在高压、小流量矿浆输送方面空白的泵种，它与一般的主要区别是：利用液压泵取代了曲柄连杆、减速器等一系列装置直接驱动活塞运动，这使其结构大为简化，成本大大下降；但同时也要求活塞的换向时机要把握得非常准确，而要实现这一点理论上和实际上都存在很大难度。

The design mainly works on many factors which effecting the volume efficiency of fracturing pump. These factors are working conditions of the pump,imbibitional valve,expulsive valve,clearance volume,sealing property, condensability of influent, liquid leakage and elastic defletion of pump cylinder. Based on these facors, we should induce the efficiency expression, famulate differential eguation and emulational mathematical model of fracturing pump.

In static analysis, small deflection theory of circular plate and electrostatic actuating theory are adopted to simulate electrostatic-structural coupled process. In modal analysis, harmonic response analysis and nonlinear transient dynamic analysis of pump membrane, the fluid in the pump is regarded as an additional mass acting on the pump membrane to approximately substitute the effect of fluid field on pump membrane, which reduces the amount of calculation and improves simulation efficiency.

其中在静态分析中，利用圆型薄板的小挠度变形理论和微机电系统中的静电力驱动理论来模拟静电－结构耦合过程；在泵膜的模态分析、谐响应分析以及非线性瞬态分析中，把腔内的流体当作附加质量作用在泵膜上，近似代替流场对泵膜的影响，从而减小计算量，提高了仿真效率。
