假设

We have mainly discussed the different selection of the original hypothesis and the alternative hypothesis which affected the result of hypothesis testing , and put forward a general principle how to select correctly the original hypothesis and the alternative hypothesis.

主要讨论了原假设和备择假设的不同选取对假设检验结果的影响，提出了如何正确选取原假设和备择假设的1般原则。

According to the basic principle of hypothesis testing,three kinds of one sided hypothesis testing with the same reject region at the same significant level α are given and how to choose primary hypothesis and alternative hypothesis at the actual application and correlation are also pointed out.

根据假设检验的基本原理，给出 3种单侧假设检验在相同的显著性水平下具有相同的拒绝域，并指出在实际应用中如何选择原假设和备择假设及其相互关系。

It is proved that if'sparse NP complete sets under polynomial-time Turing reductions exist'then 'SAT is polynomial-time non-adaptively search reducible to decision', and that if 'P is not equal to NP'then either'SAT is not polynomial-time non-adaptively search reducible to decision'or'SAT is not polynomial-time truth-table reducible to bounded approximable sets', and that if'P is not equal to NP'then'sparse complete sets for NP under polynomial-time disjunctive reductions do not exist'.

因为用现有的证明技术不可能绝对地解决这个假设，本文研究了这个假设与其他关于SAT结构性质的假设之间的关系，证明了如果'NP有多项式时间图灵归约下的稀疏完全集'则'SAT是多项式时间并行地搜索归约为判定'，以及如果假设'P不等于NP'，则要么'SAT不是多项式时间并行地搜索归约为判定'，要么'SAT不能用多项式时间真值表归约归约为有界可近似集'。

The artificial intelligence which reflectsdisembodied cognition attitudes has three unexamined philosophical assumptions------psychological assumption, epistemological assumption and ontological assumption.

在以无身认知思想为指导的人工智能研究背后，有三个未经检验的哲学假设：心理学假设、认识论假设和本体论假设。

These work are mainly based on two assumptions: one is called as the Deeg-Pak assumption, i.e., the crack is assumed to be an impermeable slit and thus the electric field inside the crack is equal to be zero; the other is called as the Parton assumption, i.e., a crack is treated as a permeable cut across that both the normal components of electric displacement and the tangential component of electric field are continuous.

裂纹问题：对于压电介质内的裂纹问题，近十年来人们已做了大量的理论分析工作，这些工作主要是基于两种假设：一种称之为 Deeg-Pak 假设，即假设裂纹为电非渗透的，因此裂纹内的电场等于零；另一种称之为 Parton 假设，即假设裂纹为电渗透的，且跨越裂纹上下表面电位移的法向分量和电场的切向分量是连续的。

According to the logical approach, the providing of the analysis hypothesis before the model construction is necessary. For example, the hypothesis of rational man and utility identity are for the convenient analysis, the hypothesis that the rich utility is smaller than the poor utility is for the importance of the third distribution.

按照逻辑方法，模型构建之前的分析假设的给出是必要的，比如关于"经济人"假设和效用归一假设等是为了分析的简便而作出的，关于富人效用小于穷人的效用假设是给出了第三次分配的意义所在。

Hypothetical conditions, marked in English by the backshift of verbs , receive regular treatmentin English grammar.

任何一部英语语法里都有专门的章节阐述假设条件句，因为假设条件句要求动词时态后移然而在汉语语法书里，或者根本不提假设条件这一问题，或者仅仅举例说明有的条件句表达的是与已知事实相反的&纯假设&。

Hypothesis testing involves trying to "prove" the alternative hypothesis by disproving and rejecting the null hypothesis.

假设检验--通过检验分析统计假设。假设检验力图通过否决原假设而&证明&备择假设。

Empirical results indicate that all three hypotheses of this study sustained: Hypothesis 1—"career development" and "training" in the enterprise repatriation program has positive influence on the affective organizational commitment of repatriates;"career development" has positive influence on the normative organizational commitment;"career development","training" and "compensation and benefit" has positive influence on continuance organizational commitment; Hypothesis 2—"conscientiousness" and "neuroticism" has positive influence on the affective organizational commitment;"conscientiousness" and has positive influence on the normative organizational commitment;"neuroticism" has positive influence on the continuance organizational commitment; and Hypothesis 3—"openness to experience" and "emotional stability" can enhance affective organizational commitment when "career development" is implemented by the organization;"openness to experience" can enhance affective organizational commitment when "training" is implemented by the organization;"conscientiousness" can reduce continuance organizational commitment when "career development" is implemented by the organization;"emotional stability" can reduce continuance organizational commitment when "compensation and benefit" is implemented by the organization; and "extraversion" can reduce continuance organizational commitment when "job arrangement" is implemented by the organization.

实证结果显示，本研究三大假设皆达部份成立，第一假设：企业施行回任措施中的「前程规划」与「教育训练」将可提升回任人员情感性组织承诺、施行「前程规划」将可提升规范性组织承诺、施行「前程规划」、「教育训练」与「薪酬管理」将会提升持续性组织承诺。第二假设：回任人员「严谨性」与「情绪稳定性」特质可提升回任人员情感性组织承诺、「严谨性」特质可提升规范性组织承诺、「情绪敏感性」特质将会提升持续性组织承诺。第三假设：「严谨性」与「情绪稳定性」特质对组织施行「前程规划」可提升情感性组织承诺、「开放的学习性」对「教育训练」施行可提升情感性组织承诺、「严谨性」对「前程规划」施行可降低持续性组织承诺、「情绪稳定性」对「薪酬管理」施行可降低持续性组织承诺、「外向性」对「工作安排」施行可降低持续性组织承诺。兹就上述结果提供对企业与后续研究者的建议。对企业的建议为：1。企业在回任措施中应加强前程规划的设计：企业除了就短期的薪酬与工作安排条件让回任员工愿意留任，亦应思考如要让回任员工能够投入工作中，长期的规划与发展不可缺少。2。外派人员人格特质甄选工具的运用：为了能找到具备严谨性、情绪稳定性与开放的学习性特质的人选，甄选用的工具即扮演著十分重要的角色，可利用人格特质测验、面谈等甄选工具。

The other assumptions are the going-concern assumption, the accounting period assumption, and the stable money-unit assumption.

主要概念是会计主体概念，其他的假设有持续经营假设，会计期间假设，稳定货币单位假设。
