第二，筛选到一种能够促进PC细胞突起生长的药物的小分子化合物：Polygalasaponin G-type皂甙。

Gas molecules move freely among one another. The result is gas molecules diffuse from high-pressure area toward low-pressure area. The process is called gas diffusion.

气体分子不停的进行着无定向的运动，其结果是气体分子从分压高处向分压低处发生净转移，这一过程称为气体扩散。

裂化有时通过催化作用对复合物的热分解，尤指把石油分子分解成更小的分子并提取低沸点的分馏部分，如汽油

By using lysozyme as model protein, this equation was tested with the renaturation process of three kinds of denatured lysozyme molecules in urea and guanidine hydrochloride solutions, and it was found that the renaturation results of denatured lysozymes could be described well by this equation, and these denatured lysozyme molecules had a tendency to form a bi-molecular intermediate aggregate in both solutions.

以三种溶菌酶在脲和盐酸胍溶液中的变性-复性过程对此方程进行了验证，结果表明所给出的方程能够很好地描述三种溶菌酶在这两种变性液中的复性结果，三种溶菌酶在两种变性液中有形成二分子集聚体的趋势。

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。
