第五节音位 音位是一种语言或方言中能区别意义的最小的语音单位。 一、音位的特征 例如:[a]】在汉语中不区别意义。 在法语中区别意义ptte(爪子)pate(浆糊) 1.音位是能区别意义的语音单位。 音素音质上的差别有两种性质: 一种是对立性差别汉语的/p/一/p/法语的/a/—ㄧ 一种是非对立性差别汉语的/a/—英语的/p//p/ 2音位是最小的语音单位。 3.音位总是属于某种特定的语言或方言的

1 Induction Recall the principle of induction: Principle of Induction. Let P(n) be a predicate. If ·P(0) is true,an for all nE N, P(n) implies P(n+1), then P(n) is true for all nE N As an example let's try to find a simple expression equal to the following sum and then use induction to prove our guess correct 1·2+2·3+3:4+…+n·(mn+1) To help find an equivalent expression, we could try evaluating the sum for some small n and(with the help of a computer) some larger n sum

1 Logic A proposition is a statement that is either true or false. Propositions can be joined by \and\, \or\, \not\, \implies\, or \if and only if\. For each of these connective, the defini- tion and notational shorthand are given in the table below. Here A and B denote arbitrary propositions

1 Case analysis The proof of a statement can sometimes be broken down into can be tackled individually 1.1 The method In order to prove a proposition P using case analysis Write, We use case analysis Identify a sequence of conditions, at least one of which must hold. (If this is not obvious, you must prove it

SUPPLY CHAIN VISIONS LOGISTICS TERMS and GLOSSARY Updated October 2003 ABB: See Activity Based Budgeting ABC: See Activity Based Costing ABC Classification: Classification of a group of items in decreasing order of annual dollar volume or other criteria. This array is then split into three classes called A, B, and C. The A group represents 10-20% by number of items and 50-70% by projected dollar volume. The next grouping, B, represents about 20% of the items and about 20% of the dollar volume. The
