1. Introduction
Turbulence is a frequently occurring phenomenon in the boundary layer and may pose a threat to low-flying aircraft and aircraft during the take-off and landing phases of flight. In addition, gusty surface winds, the manifestation of turbulence in the boundary layer, may also be a hazard to ground transportation and enhance fire danger. Therefore, a nu

铁素体不锈钢固体氧化物燃料电池中,镀膜、修饰、合金材
料的研究进展
摘要:铁素体不锈钢材料并非专门为了作为连接材料而设计,但现在已经成为固体燃料电池(SOFC)中标准的连接材料。人们容易在市场上购买该材料,然而它的使用,特别是作为阴极材料使用时,会呈现出了一系列问题,这也是导致燃料电池早期衰退的原因。上诉的问题有:瞬变电阻的快速增长和氧化物中铬的蒸发,引起阴极铬中毒使电池失效。在过去的几年里,研究人员为了避免此类问题的发生,设计了各种传导/防护材料、表面修饰材料和合金材料。本文客观地综述了目前的相关研究,将不同的方法进行了分类、总结,并一一举例说明。最后,对未来该领域的研究做了展望。

Abstract:P Ferritic stainless steels have become the standard material for solid oxide fuel cell (SOFC) interconnect applications. The use of commercially available ferritic stainless steels, not speci
Preliminary analysis of a recent experiment by F. A. Bovino
An analysis is made of the results of a recent polarization correlation experiment by Bovino (unpublished) where about 60,000 data have been obtained. I assume that the state of the photon pairs produced in the source (a non-linear crystal) are in a (sligh
