简介：紫外(紫外)放射穿上重要效果生态系统，环境，和人的健康，以及大气的过程和气候变化。二紫外放射数据集在这份报纸被描述。一个人时时包含从2005～2015在40个中国生态系统研究网络车站测量的紫外放射的观察。CUV3宽带辐射计被用来观察紫外放射，与5%的精确性，它满足世界气象学组织测量标准。极值方法被用来控制测量数据集的质量。另外的数据集包含用与一个混合模型相结合的一个所有天空评价模型是计算的每天累积的紫外放射估计。从1961～2014的重建的每天紫外的放射数据跨度。吝啬的绝对偏爱错误和root-mean-square错误至多比30%小吝啬的偏爱错误价值的车站，和大多数是否定的，它显示紫外放射紧张的低估。这些数据集能在紫外放射改进我们空间、时间的变化的基本知识。另外，这些数据集能在潜力的研究被使用臭氧形成和大气的氧化，以及生态的进程的模拟。

简介：与称为超点阵的各种各样的配置覆盖同量的光格子能导致异国情调的格子拓扑学并且，接着新奇物理的发现。在这学习，由重叠格子的最大值，新孤立的结构被创造，当最小的干扰能产生各种各样的sublattice模式时。原始格子的三种不同类型被用来表明孤立的平方，在二维的光超点阵，其模式能被调节极化动态地操作的三角形、六角形的sublattice结构，频率，和激光横梁的紧张。另外，我们建议改变相对阶段在sublattices调整通道振幅的方法。我们的配置提供唯一的机会在交叉形成的格子学习粒子纠纷井并且在异国情调的格子几何学实现特殊的量逻辑门。

简介：与spintronics的发展，在二维的材料的氧的行为上的调查从来没停止过。由于它的活泼的性质，氧是难的在系统独自存在。然而，它将与另外的原子交往并且生产复杂轨道的杂交效果，它影响了材料的表演。特别为在nanoscale的材料，介绍氧原子是不可避免的，不管什么在准备的过程或采用。因此，在二维的薄电影关于氧行为的效果继续研究是必要的。在这篇论文，它将主要在磁性，电的性质，阶段转变，纺纱依赖者性质和热稳定性上介绍氧行为的效果，总结影响氧行为的几个因素，并且概括在氧行为后面的机制的研究进步。
