Abstract. It is widely researched and confirmed in traditional track and field events that the athletes nutrition and supplement testing of anaerobic endurance track and field events could make nutritional integration which may come from different nutrient sources. However, some existing athletes nutrition and supplement testing methods could not adapt the application of Wireless Scanning Technology Flow for the reason that these existing methods include iterative process. As far as the Wireless Scanning Technology Flow is concerned, this technology flow has obvious characteristics and also make an survey on athletes nutrition and supplement testing of anaerobic endurance track and field events from the perspective of data flow. On this basis, this article could make effective use of wireless scanning data and also advance strategies which could make a frequency conversion evaluation on reliability of nutrient sources, and this strategy could decrease these required iterative process, and also increase efficiency during different time. And this article proposes a algorithm named HQW which could be used to make frequency conversion evaluation on reliability of nutrient sources. The HQW combines historical data and determines the evaluation moment of reliability of nutrient sources dynamically, this algorithm not only insure the athletes nutrition and supplement testing of anaerobic endurance track and field events could research the standard, but also increase efficiency. At last, this paper further validates the efficiency and accuracy of HQW on perception and handling of athletes nutrition and supplement testing by wireless scanning technology flow through the experiment on the real wireless scanning data set.

Abstract. Three-dimensional digital image expression model generalizes two-dimension morphological algorithm to three dimension, giving embedded wavelet image encryption algorithm based on three-dimensional digital image and its application in track and field route optimization. As to the three-dimensional digital image, it proposes the partition method based on three-dimensional wavelet encryption and embedded analysis. To do expansion and embedded analysis of three-dimensional digital image, it gets optimization result of track and field route image, discusses the relation between these two parameters, track and field route image resolution and route interval, chooses instance data to experiment and makes a comparison between data result and MaxRota algorithm, four-side encryption algorithm, analyzing the advantages and disadvantages between the method in this article and other two methods from such aspects as partition evaluation factor, precision, computational efficiency, etc. At last, it analyzes the stability of the method in this article.
