Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The Janus structure of ZnIn2S4 (ZIS) endows it with an intrinsic built‐in electric field that effectively drives photogenerated charge separation. However, this very structure also renders the predominant (001) facet (In–S termination) catalytically inert due to its low electron density and high energy barrier for the hydrogen evolution ...

, 2005 采用数值分析的方法,对含三维埋藏椭圆型裂纹的构件放电瞬间的耦合场进行分析。计算脉冲放电瞬间椭圆形裂纹尖端附近的温度场和等效应力场的分布状态;并通过改变模型尺寸的模拟分析影响放电参数的主要因素。计算结果表明,由于电流绕流产生的焦耳热源的作用,裂纹尖端处温度瞬时急剧升高,但沿椭圆形裂纹尖端的温度值并不相同,最大值发生在长轴附近,只要放电电流的强度足够大,可以使椭圆环形裂尖均熔化形成焊口,并围绕环形裂纹尖端附近产生很大的热压应力场,可有效地遏制裂纹的扩展;在相同放电电流强度下 ...
