简介：我们为基于波前错误和isoluminant颜色对比敏感功能(CSF)的大小决定孤立的颜色机制的神经对比敏感功能(NCSF)建议一个新方法。与传统的方法相比，这种技术避免协调噪音和点缀噪音，它被激光横梁的干扰带，并且为不同颜色机制的NCSF的大小有大灵活性。当蓝机制的那些是最低的时，我们的实验显示分别地，红机制的吝啬的NCSF和CSF比绿机制的那些高。然而，在红、绿的机制之间的NCSF和CSF的山峰的相对高度在题目变化。有一些个人，NCSF的价值或绿机制的CSF其山峰比红机制的高。孤立的颜色机制的NCSF和CSF都展出类似的特征和变化趋势。与统计一般水准，红、绿、蓝的机制的NCSF比在整个空间频率的相应CSF高。与相应CSF曲线相比，孤立的颜色机制的NCSF的山峰向更高空间的频率变，特别为有3.9c/deg的最大的移动的蓝机制的。[从作者抽象]

简介：这篇论文的主要目的是在中国给出历史和nanophotonics研究的当前的地位的简短概述，并且在中国nanophotonics社区做的过去的年里加亮一些研究结果。我将简短首先介绍nanophotonics的原则，几个它的学生惩罚包括photonic晶体，plasmonics和metamaterials，和相关人工的声学的结构。然后，我将加亮中国研究组在这些区域取得，选择基于我的个人味道仅仅做了的一些主要进步。目的是让研究人员更好在nanophotonics和相关区域的中国社区知道并且欣赏的这些结果，并且在不同区域提供研究人员的更好的机会有更多的通讯。我也希望这简短介绍将帮助做一座更好的桥在世界上与更宽广的社区连接中国nanophotonics社区。
