Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Bimodal grain structure (BGS) demonstrates significant potential in synergistically optimizing the strength and plasticity of magnesium alloys. Acquiring the desired BGS consequently became a critical challenge. This study took the Mg‐9Gd‐1Zn‐0.5Zr (wt%, VZ91K) alloy as its subject. From the perspective of BGS formation mechanisms, it suggests

Zhongguo shiyan zhenduanxue, 2018 结核病是一种由结核分枝杆菌引起的慢性传染性疾病,现已被WHO列为需要重点控制的三大类传染病之一[1-3]。近些年来结核病的耐药率不断升高,耐药性结核病已严重威胁人类的健康[4]。因此,对结核病进行早诊断、早治疗、控制传染源至关重要[5]。本研究采用T-SPOT.TB和CLEIA两种方法检测疑似结核病患者的结核分枝杆菌的感染情况,并对两组结果进行对比分析,探讨其检测的可靠性及对结核病诊断的临床价值。
