physical tracing
1.A new algorithm for RCS of complex objects was proposed based on ray-tracing and Physical Optics(PO) theory. The algorithm is realized on GPU to use the ability of graphics hardware.
2.Aiming at some problems of national fitness monitoring, the research makes corresponding suggestions including that China should establish territorial fitness assessment criterion, the weighting of different index should be considered in the fitness synthesis assessment, The investigation of psychology and adaptive faculty should be added to fitness monitoring, at the same time, physical activity and nutrition questionnaire should be adopted, the apparatus which be used in fitness monitoring should be manufactured through strict quality control standard and the research should strengthen portrait tracing observation against fitness index.
