简介：总数的长期的趋势出现太阳的放射(SSR)，表面弥漫的放射，和表面空气温度在在SSR之间的中国，然后关联从55个观察车站基于更新的48年的数据在这研究被分析并且日报温度范围(数据终端就绪)被学习。在中国的表面空气温度上的全部的太阳的放射的效果根据上述分析被调查。在SSR和数据终端就绪之间的强壮的关联被作出对有利的裁决时期19612008在中国。最高的关联和最陡峭的回归线斜坡发生在冬季，显示数据终端就绪上的太阳的放射效果在这个季节是最大的。云和水蒸汽在SSR和数据终端就绪上有强烈影响，并且因此在他们的关系上。在SSR和数据终端就绪之间的最大的关联在北中国发生在冬，不管全天(包括的晴朗的天和多云的天)或清楚天的案例。我们的结果也证明放射在表面到达中国在19611989期间显著地减少了(dimming时期)，但是开始在19902008期间增加了(使明亮的时期)，与以前的全球研究一致。全部的SSR的减小部分抵消在19611989期间温暖的温室。随在1990以后的SSR的增加，然而，这抵消的效果消失了；相反，它甚至做了贡献到加速的温暖。尽管如此，因为在19612008的整个学习时期增加最小、吝啬的表面温度，温暖的温室仍然起了一个控制作用。我们估计温室气体可能独自引起了表面温度上升0.310.46

简介：在过去的十年，nanopores为各种各样的潜在的应用程序广泛地被开发了，并且他们的性能极大地取决于nanopores的表面性质。原子层免职(ALD)是为扔薄电影的一种新技术，它很快从一种壁龛技术被开发了到一个确定的方法。ALD电影能保角地甚至在nanoscale在限制区域盖住表面，因此，是一个强大的工具修改合成nanopores并且也的表面制作复杂nanopores被证明。这评论在nanopore合成和ALD基本知识上给简短介绍，然后集中于由ALD和他们的应用程序处理的合成nanopores的各种各样的方面，包括单个分子的察觉到，nanofluidic设备，nanostructure制造和另外的应用程序。

简介：空气动力学的粗糙长度与nearsurface一起显著地变化，这以前被显示出大气的热力学的状态；目前，然而，这现象糟糕留下理解，并且很，有关这个话题的很少研究都没被进行。在这篇论文，由使用不同位于诺思中国下面的数据，表面在半干旱、干旱的区域上在由试验性的合作观察和不可分的研究提供了，空气动力学的粗糙长度(z0)在稳定、中立、不稳定的大气的层化的价值与对方相比，并且在z之间的关系0并且大气的热力学的稳定性()被分析。它被发现0显示出的那z大在稳定、中立、不稳定的大气的热力学的国家之中的差别，与在0在充分热力学的稳定的条件和中立条件之间珍视的z的差别到达60%吝啬的z0。而且，在风数据对z在哪个不太敏感为风速度变化0，0更显著地改变与，并且是的表面z高度与Monin-Obukhov稳定性(0)和全面理查森数字(Rib)相关，与两个他们在马厩和不稳定的大气的层化的比0.71和0.47大的关联系数分别地。与试验性的观察适合的实验关系与在稳定的空气的Zilitinkevich理论关系相当一致，但是二是在在不稳定的空气的变化趋势对面的相当不同、平的表演。然而，在申请，由使用试验性的数据的实验适合的关系的确认发现适合的关系是比在稳定的大气的层化的Zilitinkevich理论关系稍微更适用的，但是它是比在不稳定的大气的层化的Zilitinkevich关系更合适的。
