In this case, the listener usually has two kinds of response: to ask for clarifications engender negative feelings Finally, when the speaker uses "gaigen" expression to communicate a message, there is no misunderstanding is because: the authority of the speaker the listener knows the speaker is telling his opinion but not about fact And the speaker uses "gaigen" expression to communicate a message, misunderstanding causes because: the discourse maker and the information content was recognized differently (EX: the speaker pay attention to the information, but the listener pay attention to the discourse maker) the communication goal was different (EX: the listener needs the information as a fact, but the speaker offers his own opinion) the use of "gaigen" expression as a discourse maker was differently used by the speaker and listener (EX: A's using of "perhaps" has a huge difference from the one of B) By examining written sentences and written dialogues (2 people talking), the two kinds of language phenomena "representing the determinate information indeterminately" and "representing the indeterminate information determinately" was solved by analyzing the language data carefully.

最后，使用概言表现传递不确定讯息时，而会导致误会产生，是因为下列其中因素之一出现：(1)谈话标帜跟讯息内容认知的不一致（例如其中一方注意的是谈话标帜，而另一方注意的是讯息内容）(2)说者与听者间会话目标的不一致（例如听者所需要的是「事实讯息」，但说者所提供的是个人的「意见讯息」）(3)使用概言表现的用法的不一致（例如甲所使用的「大概」跟乙所使用的「大概」差距太大）。透过分析与归纳的结果，本稿最初提出的「确定的事物却使用不确定的语气描述」、以及「不确定的事物却使用确定的语气描述」之语言现象亦得到了解答。

In this paper, our work begins with the classification of inde- finite information presented in the first chapter and these classes include randomicity, fuzziness, non-partitionality, incomparability, incompleteness and unreliability. And the corresponding theories and methods of studying these information are simply described.

In her view, is too uncertain policy environment lacking the support of the legal deficiencies austerity,"the rich have the right to waste, no one管不着," according to the law should not make the appropriate and effective supervision and management, lack of shock perturbation force.

在她看来，是十分不确定的政策环境缺乏的紧缩法律缺陷的支持，&富人的权利，废物，没有人管不着，&按照法律不应该作出适当和有效的监督管理，缺乏冲击扰动力量。

The article analyzed the main resources of the uncertainty of the measurement, which include uncertainty of the working curve, uncertainty of the resolution ratio of the instrument, uncertainty of measure unrepeatability, uncertainty of standard solution, etc. It quantified these uncertainties respectively and composed them to a standard uncertainty. Finally it got the expanded uncertainty of the total organic carbon measurement.
