看paper

[cyshen (喔喔喔)]

老師發了一份paper要我們回去讀
光是其中一小段
就讓我百思不得其解
想跟各位請教一下

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譯的結果:

In speaking of the “crucial assumption” of a theory, we are trying to state
the key elements of the abstract model.
=>談到一個理論的關鍵假設時，我相信我們一直在試圖去陳述抽象模型的關鍵元素。

翻成中文之後
還是霧颯颯
這一段話到底意所何指?
我試著去理解
比如說談到消費者理論的理性假設時
教科書的作者就會用某些方法來陳述模型的關鍵元素
比如說凸向原點的無異曲線之類的
目的是讓讀者了解
關鍵假設會造成模型中什麼樣的關鍵元素
不知道我這樣理解對不對?

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－普遍來說，許多不同的假設組隱含了模型本身也被模
  型所隱含。這些都是邏輯上相等的：那些從某個觀點被視為公理和假設的，能夠從另一
  個觀點被視為定理，反之亦然。

這一段也不太懂在講什麼
感覺上只是在說:假設推導出模型,模型也包含了假設
不過後面的: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.
=>那些被稱作”關鍵”的特別假設，是以一些像是如下的方面為由被選出的：在描述模型
  上很簡單或是很節省、直覺上似乎有道理的，或是有暗示的能力，假如只是藉由暗示，
  一些要考慮的事項就會和判斷以及應用模型有關。

這段應該是說
那些關鍵的假設是怎麼被選擇的
比如說能夠簡化模型
(這裡的economy要怎麼翻 我也搞不太清楚 翻成節省也怪怪的)
或是直覺上似乎合理
亦或是有暗示的能力
(為什麼不選有明示能力的假設?)
最後的if only by implication, some of the considerations that are relevant in
judging or applying the model.
我實在不知道怎麼翻比較好
硬翻的結果
連中文也看不懂...
到底是什麼意思呢?

(文章裡面常常會出現implication這個字 是不是應該翻成"含意"呢?)

唉...
不知道到底是英文不好還是經濟學沒學好
光是一小段文章
就花了我好幾個小時還搞不懂

如果各位願意撥空給我一些指教
真的是萬分感謝<(_ _)>
