In the strict sense, it is not very clear why with magnetic field increasing, the normal-superconductive (NS) transition becomes broad for Bi2.r2.aCu2.8+δ(Bi2.12. while the NS transitions are almost parallel for La193Sroo7Cu04+δ(La2.4). In this paper, R-T relations are measured by the six-probe method. We propose a moving mechanism of the pancake vortex and vortex line for Bi2.12. The theoretical curves fit the experiment data well.

代码搜索是当下自然语言处理和软件工程交叉领域的一个重要分支.开发高效的代码搜索算法能够显著提高代码重用的能力,从而有效提高软件开发人员的工作效率.代码搜索任务是以描述代码片段功能的自然语言作为输入,在海量代码库中搜索得到相关代码片段的过程.基于序列模型的代码搜索方法DeepCS虽然取得了很好的效果,但这种方法不能捕捉代码的深层语义.基于图嵌入的代码搜索方法GraphSearchNet能缓解这个问题,但没有对代码与文本进行细粒度匹配,也忽视了代码图和文本图的全局关系.为了解决以上局限性,提出基于关系图卷积网络的代码搜索方法,对构建的文本图和代码图编码,从节点层面对文本查询和代码片段进行细粒度匹配,并应用神经张量网络捕捉它们的全局关系.在两个公开数据集上的实验结果表明,所提方法比先进的基线模型DeepCS和GraphSearchNet搜索精度更高.
