Gaoya dianqi, 2016 随着特高压电网的建设,复合绝缘子以其优异的性能已被大量采用,然而表面电荷积聚将导致其沿面闪络电压下降,影响电网运行的稳定性。为了研究表面电荷的积聚效应,建立了复合绝缘子二维轴对称模型,并使用COMSOL软件对该模型进行了研究。研究表明:伞群表面是电荷积聚的主要位置,当其积聚电荷的极性不同时,对原电场分布的影响也不同。分析认为,负极性电荷积聚为电子越过伞群向前发展创造了有利条件,缩短了爬电距离,这可能是导致复合绝缘子闪络电压下降的原因;又对表面电荷积聚情况进行了实验测量 ...

The role of arsenic nano-drug in the treatment of liver cancer [PDF]
, 2015 目的：三氧化二砷（ATO）是临床上能够有效治疗急性早幼粒细胞性白血病的药物。然而，由于治疗剂量限制和药代动力学欠佳，影响了它在抗肿瘤治疗中的运用。亲合体（Affibody）是一类新型独特的蛋白结合配体，分子量小、亲和力强、稳定且可修饰，比普通抗体具有更多优势。目前国内外尚无将亲合体用于肝癌靶向治疗的研究。为了更加有效地将ATO药物运输到肝癌细胞并产生更高的毒性，我们前期已经合成了两种新型砷纳米药物：EGFR靶向修饰的镍砷纳米药物（Ni,As@SiO2-Affibody）、锰砷纳米药物（Mn,As ...
