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

An analysis is made of the results of a recent polarization correlation experiment by Bovino (unpublished) where about 60,000 data have been obtained.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
