The existing evaluation methods have the problem of imperfect teaching effect evaluation model, which leads to the low reliability of the evaluation index. This paper designs a corpus based quantitative analysis method for teaching effect evaluation of Electronic Engineering English. Based on the mathematical principle of radial basis function, this paper uses corpus to analyze the distribution characteristics of Electronic Engineering English courses quantitatively, and uses association rules algorithm to build an English teaching effect evaluation model to comprehensively judge the importance of each factor. Experimental results: the average reliability of the two existing evaluation methods is 1.0751 and 0.5455 respectively, and the average reliability of the evaluation method is 0.7983, which shows that the reliability of the evaluation method is closer to the standard value of 0.8, which proves that the evaluation method of Electronic Engineering English teaching effect integrated with quantitative analysis of corpus has better practical application performance good.

Abstract. The geographical condition is a very important component of a country's national condition, and geographical conditions monitoring (GCM) has been a great concern to the Chinese government. In accordance with application areas, GCM can be divided into fundamental monitoring, thematic monitoring, and disaster monitoring. Thematic monitoring is a special type of designated subject monitoring that concerns the public or the government. This paper mainly discusses the quality evaluating method of thematic monitoring results (TMRs). Based on analysis, referring to GB/T 24356-2009 “Quality Inspection and Acceptance of Surveying and Mapping Achievements”, TMRs data Including monitoring data results, analysis and evaluation results, map results and monitoring report results. The operability of the quality evaluation model is illustrated by a case study of the quality inspection of urban geographic national condition monitoring.

Environment Quality

Against the background that ecological environment quality has become a hot research topic in recent years, ecological environment quality assessment has emerged as an emerging discipline. By adopting scientific methods, it objectively and quantitatively reveals the real situation of ecological environment quality, and is committed to providing support basis for environmental protection and comprehensive prevention and control. Therefore, how to develop a reasonable eco-environmental quality assessment system has become the focus of attention. Based on this, this paper summarizes the research results in this field at home and abroad, and discusses and illustrates the main existing evaluation methods and evaluation models through horizontal and vertical analysis. The development status of ecological environment quality evaluation research field and the application characteristics of different evaluation methods are analyzed, some problems in theoretical innovation, model construction and application of conclusions are discussed, and the development trend of ecological environment quality evaluation research is proposed based on this.

In this study, we carried out subjective evaluation tests employing 19 refrigerator door closing sounds to quantify the luxury feeling. By applying factor analysis to the subjective evaluation results, the sound quality of the refrigerator door closing sound was found to be expressed by the following two factors: overall loudness and the pitch of the sound. Subsequently, luxury feeling evaluation model was obtained through multiple regression analysis. As the result, the luxury feeling of the door closing sound was evaluated to be high when the sound was softer and had lower pitch. Then, we prepared several luxury door closing sounds according to the obtained evaluation model through a filter processing and conducted subjective evaluation tests again to verify the evaluation model. The result shows that the amplitude increased sound at low frequency band under 100 Hz, which was calculated to be high luxury by the evaluation model, was actually evaluated as the best among the presented sounds through the subjective test. And the luxury sound quality evaluation method was confirmed to be useful to quantify and estimate the sound quality of the refrigerator door closing sound.

Abstract. In recent years, China has promulgated the "Civil Code of the People's Republic of China", "Implementation Rules of the Provisional Regulations on Real Estate Registration" and other laws and regulations, which have protected citizens' rights and obligations in real estate from the legal system. It shows that the quality of real estate registration data is very important. At present, there is no set of standards for evaluating the quality of real estate registration data. This article sorts out the production process of real estate registration data and focuses on the four stages of production: digitization results, field surveys and surveying and mapping results, group building results, integration and association. As a result, the main points of real estate registration data quality control were put forward, and a quality evaluation model was developed. Taking Beijing's real estate registration historical archives integrated data quality inspection as an application case, it shows that the quality evaluation model has been successfully applied to actual projects, ensuring the quality of Beijing real estate registration data. It also provides a reference for the next step in China's quality control of the unified registration of natural resources confirmation.

Aiming at the problem of low accuracy of the current English interpretation teaching quality evaluation, a teaching quality evaluation method based on a genetic algorithm (GA) optimized RBF neural network is proposed. First, the principal component analysis is used to select the teaching quality evaluation index, and then design The RBF neural network teaching evaluation model is used, and GA is used to optimize the initial weights of the RBF neural network. Experimental results show that this method can effectively evaluate the quality of English interpretation teaching, and has high accuracy and real-time performance.

Complex Information

The soy sauce samples established a model for its flavour quality evaluation. Initially, 39 types of flavour compounds, organic acids and free amino acids in six different types of soy sauce were identified and determined by HS-SPME GC/MS and HPLC. The model was developed based on the principal component analysis method for assessing and ranking of flavour quality of soy sauce. Using the principal component analysis which simplifies complex information, our correlative evaluation model was established, tested by comparing the traditional sensory evaluation method, providing a new methodology for objective evaluation of the flavour quality of soy sauce.
