查询词典 critical

The critical rationalism proofs that the demarcation standard between science and non-science is falsifiability; but Feyerabend insists that the demarcation standard between science and non-science should be cleared up. The core of critical rationalism is perjury methodology. He considers the scientific method is not induction but deduce inspection. Feyerabend retorts critical rationalism School still can't be escaped from angle of view of the logical empiricism.

批判理性主义论证了科学与非科学的划界标准是可证伪的；而费耶阿本德主张消解科学与非科学的划界标准；批判理性主义的核心思想是证伪主义方法论，认为科学的方法不是归纳法而是演绎检验法，费耶阿本德反驳到：批判理性主义学派依然逃脱不了逻辑经验主义学派的"经验论"视角。

Since the solutions of this problem are the critical points of the associated energy function. One generally needs some compactness such as PScondition or C-condition to prove the existence of critical points of the energy func-tion, but when we study the elliptic equation in R~N, the compactness condition does not always hold since the imbedding of the Sobolev space H_0~(1,2)into L~(2*) is not compact. In this chapter, based on the nonsmooth critical point theory, and by using the approximation technique with periodic function, the existence of nontrivial solution is obtained.

由于该方程的解就是其所对应的能量泛函的临界点，通常都要在一些紧型条件的基础上来证明其所对应的能量泛函临界点的存在性，但当我们在无界域上考虑该椭圆方程解的存在性时，Sobolev空间H_0~(1，2)到L~(2*)的嵌入非紧，从而导致所对应的能量泛函失去紧性，本章在非光滑临界点理论的基础上，应用周期逼近的方法证明该问题非平凡解的存在性。
