Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT This study demonstrates a new strategy for modifying the boron content to address stress‐relief cracking (SRC) in the 7CrMoVTiB10.10 alloy. First, coarse‐grained heat‐affected zone (CGHAZ) specimens with different boron contents were prepared via simulated welding thermal cycles.

Huli yanjiu, 1992 头孢菌素是一类半合成广谱抗生素,属于B—内酰胺抗生素范畴。近年来我国随着头孢菌素类抗生素在临床的广泛应用。就用于临床的可达30—40种。在日本头孢菌素类抗生素的应用已大大超过了青霉素,成为治疗细菌感染性疾病应用最多的抗生素。发生过敏反应的病例也屡有报道。鉴于头孢类抗生素与青霉素之间有不同的交叉过敏反应,头孢菌素类过敏者均对青霉素过敏。而青霉素过敏者中约有10％对头孢菌素类也能引起过敏反应,儿童过敏反应低于成人5 ...

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
New Phytologist, Volume 250, Issue 2, Page 1231-1247, April 2026.Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

Zhongguo shiyan zhenduanxue, 2007 目的了解侵入性诊疗手段对抗生素应用时间的影响。方法回顾性分析60例颅脑手术后感染病人行各种侵入性诊疗手段对抗生素应用时间的影响。结果应用不同侵入性诊疗手段患者抗生素应用时间无显著差异,急诊手术较择期手术抗生素应用时间长。结论抗生素应用时间与诊疗手段的多寡无关,与手术性质有关,与侵入性手段持续时间有关。
