Advertising has become the most important part of emerging advertising media with rich content, vivid form, huge browsing volume, and exponential growth in market share. It brings huge profits to operators and advertisers participating in bidding every year. Formulate reasonable allocation rules and payment rules for advertising resources in advertising space sales. The advertising configuration platform mainly has three functions: the entry function of home page advertising, serving the company’s operation department and storing the advertising information entered by operation, with a large amount of data, involving more than a dozen tables. The advertisement output function outputs the advertisement of the storage layer through the interface in JSON data format. This part of the function serves the downstream systems, such as mobile phone clients and PC. Starting from the requirements’ analysis, this study introduces the platform design and the analysis method logic, shows the implementation of the platform, and then analyzes and describes the test process from the aspects of function and performance. Based on the review and summary of the formation and characteristics of the competitive structure of China’s advertising market and the research results of foreign advertising classification, this study makes a qualitative and quantitative study on the competitive strategy of China’s advertising game by using the principles of service marketing and advertising, the classical model of oligarch competitive structure, game theory, differential game, and dynamic optimization. In terms of qualitative research, this study discusses the impact of advertising on China’s market competition pattern and the advertising game strategy through the comparative study of advertising and the analysis of market characteristics. The study found that due to the high barriers to entry of the advertising market and the intangibility of products, the strategy of putting category advertising and information advertising should be adopted. In quantitative research, based on the Sethi model, this study discusses the advertising game strategy model of the Oligarchic competition structure. The important conclusions include the profitability of enterprises from the market share is the most important factor to determine the market share and advertising expenditure. The impact of advertising on market share is obvious. The role of advertising expenditure has a time lag. Drastic changes in the scale of advertising expenditure will cause long-term fluctuations in the market structure. The research method has a certain universality, so the research results can also be used for reference for the advertising strategy of other industries with oligopoly competition structures.

In current research on oxygen reduction reaction (ORR) catalysts for polymer electrolyte fuel cell (PEFC) cathodes, metal oxide supported Pt nanoparticles are considered to be one promising alternative to the standard carbon supported Pt, which offers the possibility of higher durability in the oxidizing environment at the PEFC cathode [1]. Detailed studies of the stability of Pt/metal oxide catalysts require the determination of the structure and surface area of the Pt nanoparticles during electrochemical durability testing. In situsmall-angle X-ray scattering (SAXS) offers the unique opportunity not only to monitor the evolution of the Pt nanoparticle size distribution in an electrochemical environment, but also to observe the evolution of the total Pt mass loading of the electrode at the same time. Furthermore, information about the dispersion/agglomeration of the Pt nanoparticles on the support surface can be inferred. Thus, the overall observed degradation of the electrochemically active surface area (ECSA) can be further analyzed in terms of different degradation phenomena like Pt loss due to dissolution, Pt nanoparticle growth due to electrochemical Ostwald ripening, and Pt nanoparticle migration and agglomeration. We have performed electrochemical in situ anomalous SAXS experiments, for the first time, on metal oxide supported Pt nanoparticles. The support consisted of a mixed iridium oxide-titanium oxide (IrO2-TiO2). The anomalous changes of the elemental scattering cross sections around the Pt LIII and the Ir LIII absorption edges were used to separate the Pt scattering contribution from the support scattering. This approach of anomalous SAXS was previously used for in situ studies of conventional carbon supported Pt [2,3]. Our results not only show that it is possible in this way to obtain a precise net Pt scattering signal even in the presence of a strongly scattering support material, but they also demonstrate clearly the existence of a previously neglected scattering interference effect due to the spatial correlations between Pt nanoparticles and support particles. This effect can become very strong for support materials containing high-Z elements like the IrO2-TiO2 support investigated in this study. However, we could also show that these particle-support interferences are non-negligible even for weakly scattering carbon supports.  We developed a novel analytical tool to take the particle-support interferences into account in the data fitting procedure with high accuracy [4]. This approach highly improves the quantitative analytical power of SAXS studies on supported catalyst materials. We applied the novel method to the analysis of in situ SAXS data from Pt/IrO2-TiO2 to study the degradation properties of this ORR catalyst during harsh electrochemical potential cycling between 0.5 V and 1.5 V vs. RHE in 0.1 M HClO4. This protocol simulates the oxidative conditions during PEFC start/stop cycles [5]. The results not only reveal a Pt particle growth due to electrochemical Ostwald ripening and a concomitant Pt mass loss due to dissolution, but also indicate a possible influence of the X-ray beam on the catalyst degradation. Hence, on the one hand, the X-ray exposure time of the catalyst must be chosen long enough in order to achieve a good signal-to-noise ratio, but on the other hand, it must be short enough to prevent X-ray induced catalyst degradation. In summary, our findings pave the way to a detailed and quantitative in situ analysis of Pt nanoparticle degradation on various metal oxide support materials.
