查询词典 uncertainty principle

So considering uncertainty variety of spatial data because of it, this paper introduces centriod as a reference point, and expanded uncertainty parameter changed with variable scales in 16-direction relation cone-shaped model and describes them with formalization. The model partitions the direction relations with smooth transition regions, which accord with percipience on direction concept description.

The uncertainty about the ultimate technical feasibility of reanimation may very well be dwarfed by the uncertainty in other factors, such as the possibility that you deanimate in the wrong kind of way (by being lost at sea, for example, or by having the brain's information content erased by Alzheimer's disease), that your cryonics company goes bust, that civilization collapses, or that people in the future won't be interested in reviving you.

复苏的最终技术可行的不确定性与其他不确定性因素相比，几乎可以忽略不计。比如，你的生命流失在一个错误的地方（像失踪在海上或大脑的信息内容被阿尔茨·海默氏病删除），你的冷冻复苏公司破产，文明崩溃，或者未来的人们没有兴趣恢复你。
