体例：this，that需要明确翻译出来。

[zhuyan166]

书和BFO本体中的例子（example）中的“this”，“that”需要明确翻译出来，因为是特指instance。

It is a basic assumption of scientific inquiry that nature is at least to some degree structured, ordered, and regular. Scientific experimentation involves in every case observations of particular instances of more general types—this eukaryote cell under that microscope, this portion of H2O in that flask, the cancer in Frank’s body (where the termsin italics pick out universals). “This” and “that” and “Frank,” here, pick out instances that can be observed in the lab or clinic. The ultimate goal of science is to use observations and manipulations of such particulars20 in order to construct, validate, or falsifygeneral statements and laws; the latter will then in their turn assist in the explanation and prediction of further real-world phenomena at the level of instances.

我觉得 “this”，“that” 可以直接翻译成 “这个”，“那个”。
