老师发了一份paper要我们回去读 光是其中一小段 就让我百思不得其解 想跟各位请教一下 原文如下: In speaking of the “crucial assumption” of a theory, we are trying to state the key elements of the abstract model. There are generally many different ways of describing the model completely-many different sets of “postulates” which both imply and are implied by the model as a whole. These are all logically equivalent: what are regarded as axioms or postulates of a model from one point of view can be regarded as theorems from another, and conversely. The particular “assumptions” termed “crucial”are selected on grounds of their convenience in some such respects as simplicity or economy in describing the model, intuitive plausibility, or capacity to suggest, if only by implication, some of the considerations that are relevant in judging or applying the model. 以下是我努力分段翻译的结果: In speaking of the “crucial assumption” of a theory, we are trying to state the key elements of the abstract model. =>谈到一个理论的关键假设时，我相信我们一直在试图去陈述抽象模型的关键元素。 翻成中文之後 还是雾飒飒 这一段话到底意所何指? 我试着去理解 比如说谈到消费者理论的理性假设时 教科书的作者就会用某些方法来陈述模型的关键元素 比如说凸向原点的无异曲线之类的 目的是让读者了解 关键假设会造成模型中什麽样的关键元素 不知道我这样理解对不对? There are generally many different ways of describing the model completely-many different sets of “postulates” which both imply and are implied by the model as a whole.These are all logically equivalent: what are regarded as axioms or postulates of a model from one point of view can be regarded as theorems from another, and conversely. =>通常有很多完整描述模型的方法－普遍来说，许多不同的假设组隐含了模型本身也被模 型所隐含。这些都是逻辑上相等的：那些从某个观点被视为公理和假设的，能够从另一 个观点被视为定理，反之亦然。 这一段也不太懂在讲什麽 感觉上只是在说:假设推导出模型,模型也包含了假设 不过後面的:what are regarded as axioms or postulates of a model from one point of view can be regarded as theorems from another, and conversely. 就真的看不懂了... The particular “assumptions” termed “crucial”are selected on grounds of their convenience in some such respects as simplicity or economy in describing the model, intuitive plausibility, or capacity to suggest, if only by implication, some of the considerations that are relevant in judging or applying the model. =>那些被称作”关键”的特别假设，是以一些像是如下的方面为由被选出的：在描述模型 上很简单或是很节省、直觉上似乎有道理的，或是有暗示的能力，假如只是藉由暗示， 一些要考虑的事项就会和判断以及应用模型有关。 这段应该是说 那些关键的假设是怎麽被选择的 比如说能够简化模型 (这里的economy要怎麽翻 我也搞不太清楚 翻成节省也怪怪的) 或是直觉上似乎合理 亦或是有暗示的能力 (为什麽不选有明示能力的假设?) 最後的if only by implication, some of the considerations that are relevant in judging or applying the model. 我实在不知道怎麽翻比较好 硬翻的结果 连中文也看不懂... 到底是什麽意思呢? (文章里面常常会出现implication这个字 是不是应该翻成"含意"呢?) 唉... 不知道到底是英文不好还是经济学没学好 光是一小段文章 就花了我好几个小时还搞不懂 如果各位愿意拨空给我一些指教 真的是万分感谢<(_ _)> --
