Commodity search engine help users find the goods that meet their needs. Existing search engines use keyword matching technology to achieve the demand. It can not correctly determine the user's needs. The search results are sorted unreasonable. The development of e-commerce platform can solve the shortage of goods and accurate search engine. This paper introduces the definition of e-commerce platform commodity and discusses the development of the technology background. It summarizes the development situation of the technology and analyzes the shortcomings of the prior art, including the value of the technology.

A new type of electric vehicle battery equalization circuit is described and analyzed in this paper. The circuit uses a two-way flyback converter and relay group to achieve energy transformation between the batteries and realize energy balance of electric vehicle battery pack, which could prevent battery over charging and over discharging. Compared to conventional equalizer, the equalizer is faster and more effective.

Agro-products processing industry should develop circular economy to alleviate the constraints of agricultural resources and ecological environment to accomplish sustainable development. With the relative theory of industry cluster, circular economy, system science, this paper expounds the connotation and definition of recycling-oriented agro-products processing industry cluster, analyzes the status and existent problems of it in Fujian, constructs the development mode of it which takes three kinds of behavioral agent as the foundation and three cycle ways as the characteristics, and integrates self-organization and organization, finally puts forward some countermeasures to promote the development of it.

The low-cost rapid recording not only improves the speed of record, but also gains an advantage of the market. It has important implications for exploring video recording. It provides resources for self-learning network platform. It can improve the quality of teaching. The development of the education sector has an important significance. The article explains the significance of the development of low-cost video recording and fast network self-learning platform. It analyzes the methods of low-cost video recording. Then we discuss the need for network analysis and self-learning platform functional planning. Self-learning network can identify shortcomings and make improvements.

It is very important for the deformation control of the bridge pile foundation in the design of bridge with high piers. Using the Three Dimensions Numerical Simulation, the stabilizing project about anchor reinforced pile foundation which is based on the geological characteristics of the 405 federal highways is simulated analyzed. According to the stimulant result, we can see that anchor reinforced pile foundation can control the dimensions effectively and reduce investment compared with the general pile foundation.
