| 1 | Robust structured light in atmospheric turbulence显示文摘Structured light is routinely used in free-space optical communication channels,both classical and quantum,where information is encoded in the spatial structure of the mode for increased bandwidth.Both real-world and experimentally simulated turbulence conditions have revealed that free-space structured light modes are perturbed in some manner by turbulence,resulting in both amplitude and phase distortions,and consequently,much attention has focused on whether one mode type is more robust than another,but with seemingly inconclusive and contradictory results.We present complex forms of structured light that are invariant under propagation through the atmosphere:the true eigenmodes of atmospheric turbulence.We provide a theoretical procedure for obtaining these eigenmodes and confirm their invariance both numerically and experimentally.Although we have demonstrated the approach on atmospheric turbulence,its generality allows it to be extended to other channels too,such as aberrated paths,underwater,and in optical fiber. | Asher Klug Cade Peters Andrew Forbes | 2023 | Advanced Photonics2023，5，1： | 1 |
| 3 | 抗刺激作用的评价——体内和体外方法的比较显示文摘香波在日常使用中对消费者无疑是一些刺激性最强的化妆品,特别是由于香波是用于身体的部分位置,即对洗涤清洗剂剥离作用特别敏感的部位如头皮、眼睛以及眼睛周围的皮肤。因此,毫不奇怪,对香波最希望的要求之一是它要'温和'。虽然洗净性和温和性似乎有矛盾,但是通过仔细选择表面活性剂和组份,使之在不严重影响效能的前提下能降低可能的刺激作用,从而可以调和这种矛盾。Johnson和Johnson婴儿香波的巨大成功证明了这一可能性。众所周知,几类化合物已显示出上述的改善效果。 | Peter Cade 李筠 | 1991 | 日用化学工业译丛1991，，6： | 0 |
