In order to systematically analyze Internet traffic features, this paper researched the taxonomy of traffic features based on the objects used for building traffic features,and overviewed the related traffic features in each category. It further analyzed the stability of traff ic features, the impact of packet sampling, network environment and obfuscating on traffic features. And then it compared the different kinds of traffic features from classification accuracy .stability, timeliness and granularity. Finally, this paper concluded future works about traffic features.

Small particle size, large specific surface area and strong water sensitivity of the Montmorillonite are the key factors that affect the quality of the reservoir, which are easy to plug the reservoir pore and throat. Dissolution characteristics of montmorillonite under alkaline conditions are the problems that researchers should pay attention to in the development of oil fields. Commonly used methods to characterize dissolution are mass contrast, X diffraction and solution concentration analysis. However, the operation of Montmorillonite quality comparison is complex, calculation of diffraction pattern by X-diffraction method has great manual operation errors, ion concentration analysisof difficult dissociation oxide Si4+ which is easily formed has great errors. So the specific surface area measured by nitrogen adsorption method was used to characterize the characteristics of montmorillonite under alkaline conditions, and the feasibility of the method is verified by comparing with the change of pH value of solution and ion concentration. Results show that the dissolved results of montmorillonite characterized by specific surface area which are measured by the nitrogen adsoiption method and the change of the pH value and the concentration of the solution are same, and it is also verified that the method is feasible. Besides, the specific surface area and pore size of the mineral can be measured directly by the nitrogen adsorption method. Nitrogen adsorption method is reliable, accurate and intuitive.
