This argument has laid the foundations of local finance theory. The purpose of our study is to analyze the effect of local expenditures and taxations on human housing location choice.

本研究之目的，即在尝试利用经济效用理论建立行为模式，以探讨地方政府财政支出和租税型态对各地区间人们住宅区位选择行为之影响关系，期能作为政府制定相关决策之参考。

Meanwhile, the method of how to learn macro-operator based on subgoals is also studied. Secondly, the situation of problem solving, in which there are no problem operator model and no any heuristics, is studied.

其次，作者针对无问题操作模型同时也无问题求解启发式信息的情况，研究如何利用训练例子，不断进行问题求解的试探，自动获取操作在不同状态集中的效用信息，形成问题求解的初步规划。

Firstly, the situation of problem solving, in which there is problem operator's model but no any heuristics, is studied. The utilities of operators applied in set of states can be obtained through the analysis of operator model, and the problem planning can be makeup in the form of subgoal hierarchic.

首先，作者针对有操作模型但无问题求解启发式信息的问题，研究如何通过自动分析操作模型获取操作在不同状态集中的效用，形成问题求解的初步规划，并利用初步规划的结果逐步求解相关子问题，从而获得整个问题的解。

Once the me-chanical tomato harvester had been developed in its basic form, a design alteration of critical social significance－the addition of electronic sorters, for example－changed the character of the machine's effects upon the balance of wealth and power in California agriculture.

一旦机械蕃茄收割机在它的基本形式上被发展出来，一种在社会意义上具关键性的设计改变－例如附挂上去的电子分类器－机器效用特性的改变，是依附在加州农业的财富与权力上的决定权。
