演绎定律

Physics concepts, theorems as well as principles are primary content of physics learning, those knowledge take on the forms by proposition . In chapter 3, the study revealed that physics proposition are mainly obtained by reasoning (inductive reasoning such as tallying method, differentiation method and covariant method, deductive reasoning such as negative expression of hypothetical inference, affirmative expression of hypothetical inference ).Then by the means of experiment, the different condition needed when applying those reasoning was explored.

由于定义性概念、定理和定律等命题知识是物理教学的主要内容，所以在第三章中首先通过研究，表明物理命题主要是运用推理策略获得的(归纳推理策略中的求同策略、差异策略和共变策略，演绎推理策略)；然后通过实验等方法研究使用策略需要的条件；最后依据前面的研究提出适合物理命题学习的任务分析方法。

Explanation, according to this view, is simply accounting for facts on the basis of a deduction from a known law or laws, or accounting for some subordinate law on the basis of a deduction from some more general law or laws.

根据这种观点，解释仅仅是在演绎的基础上说明事实，而这种演绎来自于著名的定律，或者是在演绎的基础上说明某种从属定律，这种演绎来自于更普遍的定律。

A fully-developed or advanced scientific theory is a well-organized logic deductive system which is comprised of scientific axioms, deductive propositions or scientific laws, and scientific facts.

成熟的或高级的科学理论是由科学公理、导出命题或科学定律、科学事实三大块组成的严密的逻辑演绎体系。

Ripe and advanced scientific theory is a well-organized logic deductive system. It consists of scientific axioms (basic concepts and basic hypotheses), deductive propersitions, and scientific facts.

老练的或高级的科学表面是由科学正义、导出命题或科学定律、科学真相三大块组成的缜密的逻辑演绎体系。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
