The uncertainty of objective is divided into four kinds in this paper. There are randomness, fuzziness, greyness and unascertained.

本文根据不确定性信息的不同表现将不确定性分为随机性、模糊性、灰性和未确知性四种不确定性。

I would also endorse Rizzo's critique of attempts to use objective probability theory as a way of reducing the real world of uncertainty to certainty equivalents.

我也赞同里索对客观概率论的批评，有人企图用它来减少现实世界的不确定性，使其趋近于确定的世界。

Uncertainty comes from objective thing or process itself and main body, and the complicated relation between main body and object, which has the meaning of ontology and epistemology.

它根源于客观事物或过程自身和认识主体以及认识主体与客体之间的复杂关系中，具有本体论与认识论的含义。
