可感知的

There is a gap between what we can in principle be given in perception and any belief about the past. And because in principle we could never be given anything about the past directly, the gap is one that no justified a posteriori inference could bridge. For anything to which we could appeal in support of a hypothesis about the connection between the past and present will simply give us more information about the present. Thus, unless our conception of the past is a form of idealism analogous to phenomenalism regarding the external world, skepticism follows.

在'原则上我们在感知中被给予的'和'任何关于过去的信念'之间有一个gap，又因为在原则上我们不能被直接给予过去的东西，这个gap就没有一个后天『a posteriori』inference能架桥辩护，因为任何可诉诸以支持关于过去和当前的关联的假说的东西，也不过是给我们更多关于当前的信息，如此，除非我们对过去的概念是类似关于外在世界的现象论的这种观念论的一个形式，否则怀疑论就会得到。

本文通过对浙江临海西兰花合作社的典型案例和实证分析发现，经济发达地区资本控制下的合作社呈现出明显的功能弱化现象，并同时伴随着合作社&产权锁定&特征，合作社农户仍然分散地抗御着自然风险和市场风险，同时农户对加入合作社后的利益感知程度不高而可能选择退出，信息、资本及技术的可获得性和销售的稳定性都将强烈冲击合作社的存在边界、规模和稳定性。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
