Drought stress can seriously affect tuberization,yield and quality of potato plant.However, the precise molecular mechanisms governing potato stolons response to drought stress and water supply are not very well understood.In this work, a potato (Solanumtuberosum L.) variant, Ningshu 4, was subjected to severe drought stress treatment (DT) and re-watering treatment (RWT) at tuber bulking stage.

随着输油、气管道向高压、长距离、大直径方向发展,人们对管线钢的力学性能要求越来越高.而对接环焊接头始终是管道建设和安全运营的薄弱环节,因此对环焊接头焊接工艺、微观组织和力学性能的分析,对提高环焊质量,改善对接环焊工艺具有重要的指导意义.本文对冲击韧性偏低的X80管线钢环焊接头进行了微观组织分析,并且对夹杂物形态、成分和分布进行了表征,揭示了该样品冲击韧性不合格的原因.
反铁磁材料常被用作磁性交换偏置体系的钉扎层,因而在磁记录等领域有着广泛的应用.反铁磁半导体材料可以实现和铁磁半导体的对接,对实现半导体自旋电子学有着重要的意义.在交换偏置体系中,最重要的是界面上的自旋结构,因此研究和表征反铁磁的表面自旋结构必将有助于深入理解交换偏置的本质.表面反铁磁自旋结构一直是实验探测的难点,需要原子尺度的分辨率.自旋极化扫描隧道显微镜已经在金属反铁磁材料的表面证明了其在表征非
