A miniature dynamic magnetoelectric test method by shielding coil [PDF]
, 2017 磁电效应是施加磁场产生电极化的物理效应,动态法测量磁电转换系数,是测量磁电材料的磁电效应的一类主要方法。本文尝试设计了一种屏蔽线圈式的微型磁电测; 试方法,改变了以往的电磁屏蔽方式,从屏蔽样品改为屏蔽线圈,并采用单线圈的设计,从而扩大了样品空间,提供一种可以微型化,便于嵌入低温系统的动态法磁; 电效应测试方法。Magnetoelectric effect is the effect that applied magnetic field induces; an electric polarization.

10Be和26Ai揭示的合黎山西南部侵蚀速率初步研究 [PDF]
, 2018 地表侵蚀速率是衡量地貌演化的一个重要因子。本研究利用原地宇宙成因核素 10Be 和 26Al 对合黎山西南部地表岩石侵蚀速率进行了首次测定。结果显示：约 30 ka 以来，合黎山西南部的地表岩石侵速率约为 24 mm∙ka-1。这一结果与已见报道的其他基岩侵蚀速率值一致。这一结果与 Small et al 获得的非干旱地区的基岩侵蚀速率也基本一致，但是显著高于干旱的南极地区和半干旱的澳大利亚。10Be 和26Al 获得的侵蚀速率的良好一致性表明本研究中所用侵蚀模式的有效性。所得的侵蚀速率小于 ...

A Research on the Mechanism of Mobile Phone Advertising Avoidance: Based on Grounded Theory [PDF]
, 2016 广告回避研究始于20世纪60年代，学者针对不同的媒体载具进行了大量扎实的研究。广告回避研究在根本上是对广告心理效果的研究，它不仅反映了受众对于广告信息传播的态度及基本信念，也代表了一种新的广告效果衡量指标。作为“实用主义”色彩浓厚的研究议题，广告回避研究与媒体的更新发展基本保持同一步调。但是，在移动互联网的快速普及和手机营销备受瞩目的今天，手机广告回避研究仍属于“婴幼期”，现有研究成果明显滞后于业界发展。 本文从受众的角度出发，运用扎根理论，对手机广告回避进行探索性研究 ...

The Influence of Superstrong Magnetic Fields on Thermonuclear Reaction at the Outer Crust of Magnetar [PDF]
, 2016 核天体物理领域中超强磁场的相关研究表明：磁星外壳层热核反应都与磁场密切相关。磁星的超强磁场不仅影响热核反应率和最终元素丰度，而且还影响磁星的中微子能量损失率，最终影响其演化时标、演化进程和冷却机制。由于超强磁场的重要性，本文主要研究了磁星表面壳层超强磁场对一些典型核素的热核反应的影响。 首先，基于相对论性的超强磁场理论(Fushikietal.1989)，利用Thomas-Fermi-Dirac近似方法，我们研究分析了超强磁场环境电荷屏蔽难题，讨论了电荷屏蔽对热核反应23Mg(p，gamma ...
