Abstract: The increasing demand for energy, non-renewable energy storage on Earth drastic drop in the new energy is in exploring the application stage, humans had to find a way for existing energy saving. LED (Light Emitting Diode) as a fourth-generation light source and its high photoelectric conversion efficiency, environmental protection, long life, the application of many changes and other advantages of the various countries on the national lighting issues ^[1]. This paper researched scales reflecting cup and Scheme macro language programming briefly, explained the program about scales reflecting cup written by Scheme macro language and the process of using TracePro software to product model briefly, then compared with traditional reflecting cup and analyzed.

LED (Light Emitting Diode) as a fourth-generation light source and its high photoelectric conversion efficiency, environmental protection, long life, the application of many changes and other advantages of the various countries on the national lighting issues ^[1].This paper explore the cooling area, the material and Presence of heat pipe 's Influence on the heat sink effect. Length of the heat pipe 's affect on heat pipe fin type radiator cooling effect.

Abstract: In order to solve the problem of ECG being complex, and the problem of abnormal ECG signal analysis standards being not uniform, this paper analyzes Lin Zetao’s clustering algorithm research achievements in the classification of abnormal heart rate. According to the characteristics of the clustering algorithm which is suitable for dealing with the rare data and the large amounts of data, this paper makes the analysis of the method of setting parameters in key process of the application of the clustering algorithm. This paper proposes an accurate clustering algorithm (LCFCM) about abnormal ECG which combines logical judgment, cluster analysis and fuzzy clustering together. Based on the algorithm design requirements, this algorithm perfects the logical judgment criteria and the key technologies of the ECG waveform vector extraction method. Ultimately, the MIT-BIH database is used as the sample to make experiment. The experiment shows that, this paper proposes LCFCM algorithm, whose accurate rate toward the classification of the abnormal heart rate reaches 93%. And at the same time, the good self-adaptive algorithm on different individuals ECG, has good practical value.
