Logical empirist had to lower the criterion of the principal of verifiability . at this time , carnap suggested " confirmation " principal . he studied the numeral confirmation to answer the " hume problem " and seached the logical basis of science 但他们的证实理论遭到了很多人的批评,因为证实原则不仅使形而上学命题无法证实,而且科学命题也得不到证实,于是逻辑实证主义者降低了证实标准。
China welcomes the new treaty signed by the us and russia on the reduction of their offensive strategic weapons , and hopes that these two countries will adopt effective measures to ensure the " verifiability " and " irreversibility " of nuclear disarmament , and continue to further the process of nuclear disarmament , so as to genuinely promote world peace and stability 中国欢迎美俄签署新的削减进攻性战略武器条约,希望美俄采取切实措施,确保核裁军的“可核查”和“不可逆” ,并继续推进核裁军进程,真正促进世界的和平与稳定。
Carnap ' s inductive logical system of the theory of probability confirmation is introduced in the second part of paper . firstly , some basical and important concepts are explained such as confirmation and degree of confirmation , probability1 and probability2 . in carnap ' s opinion , the difference between verifiability and confirmation is that verifiability means the hypothesis is finally proved to be true , but confirmation means it be true nowerdays . then carnap analyzed the distinction and relationship between probabilityi and probability2 他认为,证实是决定性地最后为真,而确证只是现阶段得到确定,并不保证以后也确定为真;继而分析了概率1与概率2两者之间的区别与联系;然后构建了一阶语言系统,并在其中定义了状态描述、结构描述、量程等重要概念与定理,以便使在考察归纳逻辑前提与结论时,能在该系统中根据确切的规则进行准确的分析。
