The monotony and extremum theory of function are applied to prove the geometrical characteristic of error hand for 2D linear segment uncertainty ε(subscript σ) model in theory. The result shows that the error hand has the geometrical shape of "larger ends and smaller middle" or "one end larger and the other smaller". The minimum width and its exact position of the error hand are calculated too. It is proved that the minimum width position of the error hand is near the end with the smaller mean square error.

运用函数单调性和极值理论，从理论上证明ε模型的误差带的几何特征；得到线元误差带不仅具有&两端大、中同小&，而且也可能具有&一端大、一端小&的几何形状；给出了误差带的最小带宽及其位置；论证了误差带的最小误差带宽的位置靠近中误差较小的一端。

Yi Xi grasp at any opportunity plum star's hand almost no one walking in the streets to see the time still early, we stroll the other at the bus stop near the shuttle's launching the first 5:30, almost 6:00 when the two men on the to the strong management to work out where to see Yi Xi Li Xing had never let go of his hand, and my heart a little puzzled, but does not think much of the enjoyment of the sweet beauty go hand in hand.

易夕紧紧的抓住李子星的手走在几乎没有人的街道上，看时间还早，便在汽车站附近游逛着等五点半第一班车的发动，差不多六点的时候两人就到了管明强上班的地方，李子星看易夕一直没松开他的手，心里有些奇怪，不过没有多想就享受着美人相随的甜蜜。

At length I spy'd a little Cove on the right Shore of the Creek, to which with great Pain and Difficulty I guided my Raft, and at last got so near, as that, reaching Ground with my Oar, I could thrust her directly in, but here I had like to have dipt all my Cargo in the Sea again; for that Shore lying pretty steep, that is to say sloping, there was no Place to land, but where one End of my Float, if it run on Shore, would lie so high, and the other sink lower as before, that it would endanger my Cargo again: All that I could do, was to wait 'till the Tide was at highest, keeping the Raft with my Oar like an Anchor to hold the Side of it fast to the Shore, near a flat Piece of Ground, which I expected the Water would flow over; and so it did: As soon as I found Water enough, for my Raft drew about a Foot of Water, I thrust her on upon that flat Piece of Ground, and there fasten'd or mor'd her by sticking my two broken Oars into the Ground; one on one Side near one End, and one on the other Side near the other End; and thus I lay 'till the Water ebb'd away, and left my Raft and all my Cargo safe on Shore.

最后，我终于在小河的右岸发现一个小湾。我费尽艰辛，好不容易把木排驶到最浅的地方。我用桨抵住河底，尽力把木排撑进去。可是，在这里，我几乎又一次险些把货物全都倒翻在水里。这一带河岸又陡又直，找不到可以登岸的地方。如果木排一头搁浅在岸上，另一头必定会像前次那样向下倾斜，结果货物又有滑向水里的危险。这时，我只好用桨作锚，把木排一边固定在一片靠近河岸的平坦的沙滩上，以等待潮水涨高，漫过沙滩再说。后来，潮水果然继续上涨，漫上沙滩，等水涨得够高了，我就把木排撑过去，因为木排吃水有一尺多深。到了那儿，我用两支断桨插入沙滩里，前后各一支，把木排停泊好，单等潮水退去，就可把木排和货物品平安安地留在岸上了。

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。

Please forgive me of willfulness, forgive me for the harm you inadvertently, perhaps, like the lyrics written by : Perhaps pulled a hand hand foreordination may not necessarily have a good go with the road is even more busy lives so pulled a hand made with hand So of the road years to come back next life should therefore go along with the road has not years to come back to lead you really want to take the hand continue!
