For certain bandwidth, increasing difference between high and low index and selecting out-layer material with low index are very important for achieving an excellent anti-reflectance performance. 对特定的带宽,增加两种薄膜材料的折射率差和选择尽可能低的最外层折射率对获得优良的减反射特性是非常重要的。
The structure and properties characteristics are discussed in detail with segmented cladding fiber consisting of6 low index segments as an example. 文章简单介绍了瓣状光纤的发展过程,并以低折射率瓣为6瓣的瓣状光纤为例对其结构和性能特征进行了详细介绍。
According to the temporal curve of the moisture budget, finding that the departures distributional of the precipitation with the high or low index is oppositely. 根据夏季水分收支的时间变化,得到东亚季风湿润区高低值年降水呈相反分布型。
The diffusion mechanisms of Gd adatoms on Cu low index surfaces are studied by molecular dynamics. 为了分析Gd吸附原子在Cu(001)、Cu(110)和Cu(111)表面的扩散机制,本文用分子动力学对该扩散过程进行模拟。
[ Results ] ① The CHD group indicated a high index of insulinemia ( P < 0.01 ) and a low index of insulin sensitivity ( P < 0.01 ), compared with the control group; [结果]①冠心病组患者与对照组比较,存在高胰岛素血症(P<0.01)和胰岛素敏感性降低(P<0.01);
