Methods: Unrepeated MRSA strains from clinical specimens were divided into two groups: C-MRSA and H-MRSA, We used Chelex 100 to get DNA template and amplified mecA gene by PCR. The DNA templates of MecA were used to RAPD(random amplified polymorphic DNA), then we got the RAPD-DNA fingerprint-maps, randomly sampled 20 strains from each group as study objects.

收集临床MRSA标本，将其分为社区获得性MRSA与医院获得性MRSA两组，用Chelex 100裂解法制备DNA模本，PCR扩增mecA基因，选择mecA基因的DNA模本，用RAPD技术扩增出各菌株的RAPD-DNA指纹图谱。

In this paper,by simulating different indoor and outdoor experiments of the crude oils in the different weathering environment of summer and winter,and using fluorescence spectrometry,Comparison and analysis of spectra from oils of unweathered and at different weathering times are experimentalized(crude oils from Kuwait and Saudi- Arabia,which are both light crude oils),which could identify the two similar oil species,without taking into account the biological degradation,wind speed,as well as factors such as the role of the waves,and the impact of factors,then how the fingerprints will be changed in the law have been found.

本文通过模拟不同原油在室内和室外的夏、冬两季的风化实验，运用荧光光谱法，对未风化油品和不同风化时间的油品(科威特原油和沙特阿拉伯轻质原油)进行谱图对比分析，鉴别两种相似油种，在不考虑生物降解、风速以及海浪等因素的影响，找出油指纹随风化影响因素的变化规律。

MethodsChromatographic fingerprint of Amomum villosum,Amomum chinense and Alpinia zerumbet was determined by RP-HPLC and the gradient elution mode was applied in chromatographic separation,data were analyzed by Fingerprint Similarity Evalution Software to compare the similarity of samples.

方法采用RP-HPLC法，梯度洗脱，测定阳春砂、海南假砂仁及艳山姜的指纹图谱，并作相似度比较分析。

Their innovation reported this week in Science is based on desorption electrospray ionisation an analytical technique which can be deployed in the field.

这种可能得益于德米安o伊法教授和他的同事们开发的一种新的指纹分析技术。

A two-times locating method based on the gray contrast of surroundings is presented in locating central reference point. This method has better adaptability and robustness, and can basically meet for the accuracy of automatic locating center. Fourier spectral analysis is improved to obtain a more accurate ridge frequency in computing ridge frequency. The average ridge width is used in designing Gabor filters, so the filters have certain adjustability. The rotating invariance of fingerprint images is solved by the rotating of feature models in feature matching.

在中心参考点定位部分，提出了基于局部邻域灰度对比度的二次定位方法，该方法具有较强的适应性和鲁棒性，基本满足自动中心定位的准确度要求；在频率域估计中，改进了傅立叶谱分析法，提高了纹线频率计算的准确度；引入平均纹线宽度作为Gabor滤波器的设计参数，使滤波器具有一定的自适应性；在特征匹配阶段，通过对特征模板的旋转解决指纹图像的旋转不变性问题。

It utilized self-adaptive two-row and two-column scanning algorithm,ascertained the size of edge area and center area according for each fingerprint image,the edge area was segmented as background,and then the center area was segmented by combining the gray variance method.

该方法采用双行双列扫描对每幅指纹图像自适应地划分边框区和中心区的大小，然后对边框区作去背景，对中心区结合方差法进行分割。

AIM: To establish chromatographic fingerprint of Panax gingseng C.A.
