Pass " of word of antonym word coupling or the statistical analysis that ","OR" uses a case actually in daily language, can see,"Or the meaning;" that " comparing "OR" conveys " of extract of " of logistic coupling word on taller frequency or after " and "OR" are advanced exchangeability respect difference is not big;"OR" compares " perhaps " more is upper the tendentiousness; that reveals a choice serves as antipathic choice,"OR" compares " or " show is more apparent.

概要： 通过对语词联结词"或者"、"OR"在日常语言中实际使用情况的统计分析，可以看出，"或者"比"OR"在更高的频率上表达逻辑联结词"析取"的涵义；"或者"和"OR"在前后项的可交换性方面差别不大；"OR"比"或者"更多地表现出选择的倾向性；作为不相容选择关系的"OR"比"或者"其前后项更多地满足逻辑排中律；在和其他联结词的相互转化方面，"OR"比"或者"表现更为明显。

The hydroxyls banded to octahedral Fe and Mg dehydrate at 800℃-900℃ and 900℃ 1000℃ respectively.

在500℃～600℃，水黑云母失去再水化能力，同时层间阳离子失去可交换性。

In the path integral formalism, we represent the generating functional and Green functions of Φ〓 theory by taking account of that the partial and the functional derivatives commute. Also we discuss the effective action for noncommutative scalar fields, and show how the noncommutative phase factors appear in path integral formalism. We realize that the two approaches (path integral and canonical quantizations) are completely equivalent each other.
