Therefore we have optimized the experimental system and the working status of instrument.2 The near-field SERS spectra and images for the [Ru_3]~(2+) molecule adsorbed on silver nanoparticle substrate were achieved. Based on the results, some specific phenomena for near-field SERS were found. By observing the near-field SERS spectra collected at different location at the nano-scale, the different spectral characteristics which are caused by the local environmental differences of molecules have been found. On the substrate, the highly SERS active sites are much more than SEF hot spots, and the distribution of them is not entirely consistent. This phenomenon could be explained by the influences of several factors including the different enhancement efficiencies existed for SERS and SEF, the quenching effects for fluorescence by the metal substrate and metal-coated tip, and the presence of different numbers of probing molecules in SERS and SEF.3 It is of interest that the near-field and far-field SER spectra demonstrate several distinctively different spectral features.

由于SNOM与SERS的结合在技术上将面临很多实际困难，例如近场激发信号极其微弱、纳米级微弱光谱的收集对实验精度和环境稳定性的苛刻要求等，因此我们对实验体系和仪器工作状态分别进行了优化。2获得了银纳米粒子SERS基底上[Ru_3]~(2+)分子在纳米尺度下的近场SERS光谱和图像，从中可以发现一些近场SERS效应特有的现象：通过观察不同位置得到的近场SERS光谱可以发现，在纳米尺度下，由于分子所处局域环境不同而体现出不同的光谱特征；此基底具有极高SERS活性的位点远多于表面增强荧光热点，且两者的分布并不完全一致。

Was adopted without objection for procedural matters, such as members of the General Assembly in a hearing or speech calling himself a written speech or a report included in the article "Congressional Record"; in the debate on the motion, presided over the debate on the two Send who led demands to allow members within five working days to amend his statement (In this way, lawmakers could avoid the restrictions on speaking time to correct their own mistakes or speech).

However, he was subject to strife of other senior artisans. Claude Miniyaer did not give up his enthusiasm to research on jewelry craft. Minister Mazarin called on artisans to try for new gem polishing method. Most craftsmen held the traditional concept of polishing most precious gold and pearl jewelry, while Claude Miniyaer had realized the importance of the trial and joined with several craftsmen to research on combing different gem polishing ways. By working out a new gem cut-rose cut, they discovered unique features of diamonds, thus started the diamond era.

克洛德·米尼亚尔并未因此而放弃对首饰制作的热心钻研，当路易十四的朝廷大臣马萨林征集工匠试验新的宝石琢磨法时，大部分工匠还只停留在对传统观念中最贵重的黄金和珍珠首饰大加修饰之上，克洛德·米尼亚尔却感觉到了试验的非比寻常，他恳请加入其中，和另几位工匠开始对宝石进行不同刻面相结合琢磨法的尝试，他们的努力发掘了钻石从未被发现的特性，于是，宝石玫瑰形琢磨法问世了，一个大放异彩的钻石时代也就从这里开始。
