不变性原则

文章从分析违背不变性原则的框架效应入手，从正反框架、确定选择和风险选择、风险规避和风险寻求、高估小概率事件几个方面，全面分析风险决策可能的神经基础。

The mechanisms and neural basis of framing effects that violate the invariance principle are presented and discussed from the following aspects : positive negative framing , sure choice risk option , risk aversion risk seeking , and over-weighting low probabilities .

理论与实验计算结果都表明，在一般情况下，岩石在弹性变形过程中，孔隙度是变化的，孔隙度不变性原则并不成立，因而孔隙度校正是有依据的。

The results from the theoretical and experimental analyses indicate that the porosity is normally variable during elastic deformation of rock , hence porosity correction has the basis , whereas the principle of porosity invariability is not valid .

该文将本体论引入构件设计，对构件对象的联系进行本体分析，目的在于为构件对象建立清晰、完整的本体模型，为设计遵守接口不变性原则和具有产品复用性的构件奠定基础；

Since the understanding and analysis of the association of objects is unclear in traditional modeling , this paper introduces Ontology into component development to develop the component model with semantic clearness and completeness which satisfies the need of reusability of com-ponent products , that is interface consistency .
