ID〓 is characterized by the fast speed of training and classifying, and it can be applied to large-scaled learning problems. But the selection criterion of attribute is the core of ID〓, and is now doubted. AQ〓 is a type of decision rule induction, presented by Michalski, a scientist of U. S.. It is characterized by high-precision classifying and capability of knowledge expression, and it can be applied to automatic knowledge acquisition in expert system. However, the inducing and matching speed of AQ〓 is slow.

The innovation of performance-based budgeting spreads the each state government of U.S., and this budgeting system claims regionalism and induction. The rule of budgeting system of countries is to authorize the decision-making as far as possible and to use to the place effectively. Simultaneously, the institutions also budget by the achievements to arrange in order, but not depend on the cost of investment formerly.

摘要 绩效基础预算的改革风潮几乎遍及美国各个州政府，该预算制度主张分权与诱因，各国共同作法系将使用预算资金的决策尽量授权，用於最有效率的地方；同时预算亦按各机关的产出绩效来编列，而非如以往按投入成本编列。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
