High voltage stimulation was applied to elicit MEP and record latent period of MEP at all segments and the motor nerve conduction velocity of the infraclavicular segment.

采用尺神经近段MEP、锁骨下近段MNCV及全程MEP法检测，三方法的阳性率分别为94.4%、83.3%、55.6%。说明近段MEP检出百分率高于锁骨下近段MNCV的检出率，高于全程MEP潜伏期的检出率。

Methods:The treatment of 18 cases with bone cysts was reviewed,which there were treated from January 2004 to February 2005. There were12 males and 6 females with an average age of 13 years?old. The bone cysts were located in the proximal humerus（n=9）,proximal femur（n=4）,proximal tibia（n=1）,distal tibia（n=1）,proximal ulna（n=1）,distal ulna（n=1）,and distal radius（n=1）.Under fluoroscopy, two fine bone marrow biopsy needls pierced the bone cysts from the top and the bottom of the cyst respectively.The intracystic fluid was drawn out,the cyst cavity was irrigated and then the tissue engineering complexation of autologous red bone marrow and methylprednisolone with sodium hyaluronate was injected in percutaneously.

2004.1～2005.2月，对18例骨囊肿患者（男12例，女6例，平均年龄13岁；其中肱骨近端9例，股骨近端4例，胫骨近端1例、远端1例，尺骨近端1、远端1例，桡骨远端1例）以玻璃酸钠为载体抽取自体红骨髓加入甲基强的松龙，在X线透视下，将2根骨穿针经皮分别自囊腔顶部和底部刺入骨囊肿内，抽去囊液，冲洗囊腔后注入复合物。

METHODS:Fifty two permanent maxillary first molars,which were diagnosed as pulpitis and periapical periodontitis clini cally,were selected.The pulp chamber floors were examined and detected to locate the mesiolingual canals(MB2) by naked eyes and SOM respectively.

由于其近颊根通常有近中颊和近中舌(MB2 ) 2个根管，而其近中舌根管细小且根管口常较为隐蔽，因此，Weine认为上颌第一恒磨牙根管治疗失败的一个主要原因是治疗中遗漏了MB2根管。

Exhibiting angle unconformities or erosion unconformities in different part of the basin, these surfaces are obvious to be recognized on seismic profiles.T1 conformity, separating Eogene from Neogene, was formed during the whole basin uplifting and erosion by the end of Eogene.T1 unconformity denuded unbearing strata differently, and the deeper and thickest erosion lies on the southern margin of the basin, which reflects the activity of southern Jiangnan paleo-terrene. In conclusion, the major erosion belts extending along NW direction reflects NE-SW compression and slipping caused the Eogene basin uplift and strengthen the earlier NW direction extending low convex, and formed the NW direction extending depress and erosion belts.

古近系和新近系之间的T1不整合面形成于古近纪末期的盆地整体抬升，对下伏地层造成不同程度的剥蚀，沿盆地南缘的剥蚀层位深，剥蚀量大，反映盆地南缘整体相对隆起，与江南古陆的隆起作用有关。T1界面剥蚀带走向以北西向为主，反映了盆地在古近纪末受到了北东－南西向的挤压或压扭作用，该作用造成盆地整体抬升，强化了北西向展布的低凸起，产生了近北西向的洼陷和剥蚀带。

The plum-apricot germplasm resources were analyzed by RAPD markers. The results showed that plum-apricot was more close to the related species with low polymorphism. The clustering results were indicated that most plum-apricots were more close to Chinese plum with the similarity of morphological description, thus the female parent for plum-apricot was probably plum in the occurrence naturally. The result of S allele-specific PCR amplification showed that plum-apricot had only one band with the similarity with plum, thus evolution similarity of plum-apricot was more close to plum than apricot.

5对参试杏梅种质资源的RAPD分析表明，杏梅与其近缘种之间亲缘关系较近，多态性相对较少；聚类分析结果显示大部分的杏梅与中国李的遗传距离较近，与形态学上的描述基本一致，因此杏梅种质资源在自然界中产生时，其母本可能为李；同时S等位基因的扩增结果显示杏梅与李的扩增条数一致，都为一条，因此推断杏梅与李的进化趋同性可能较杏更近。

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。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
