Measure And Auto-Interpret Analyze The Wood's Mini-Density Of Growth-Ring

This research accomplishs auto-interpretting and analyzing the wood's mini-density of growth ring measured by Scanning X-ray mini-density measure, by instituting the auto-interpretting analysis system of mini-density of the wood's growth ring.Accordding to different mini-density characteristics of the wood's growth ring, The analysis system can use four different methods: the method of valve quantity, gradient method, gradient difference method and the method of moving average line. It can auto-decides the margin rings and borderlines between the springwood and the latewood , compares and analyzes Dahurian Larch, Korean pine and Little-Seed Spruce by making use of the four methods, and preliminarily attains that : it is better to use the method of value quantity to Dahurian Larch , gradient method to Korean pine, moving average line to Little-Seed Spruce. The system can also auto-decide the false-ring by using the method of the max-quantiry helping decide, so as to eliminate the bad effect of the false-ring to interpretation, and to improve the accuracy and precision of the analysis.The system accomplishes the calculation of the main coefficients, Such as destiny of wood, ring width, latewood percentages and destiny variation etc, and reserves these coefficients as word documents. And then, by analyzing and handling these coefficients by using other quantity handle excel, we can use the effect method of the reference to find the use-interpreted method of one certain species. By using this system, it can improve the accuracy of the interpretation, offer scientific and reliable abasements to analyze and revise-composition the wood's composition. Further more, it can direct the biology foster and the wood's further procers, to attain the aim of advisable reclamate the resource of wood.
