According to the distribution of local impulse noise , an adaptive chord deviation method is used to avoid redundant detection or missing of impulse noise at the quick rising , descending or broken line area of data set 摘要針對現(xiàn)有脈沖噪聲濾波算法在處理大斜率區(qū)域和斷線型激光掃描數(shù)據(jù)中存在的多判和漏判問題,提出了一種有效檢測脈沖噪聲的方法。
By using the transfer relationship of reciprocal judgment matrices and fuzzy complementary judgment matrix in this paper , were introduced two priority methods - least logarithm square method and least olgarithm absolute deviation method 摘要利用正互反判斷矩陣與模糊互補判斷矩陣的轉換關系,探討模糊互補判斷矩陣的兩種排序方法對數(shù)最小二乘法和對數(shù)最小一乘法。
By using the standard deviation method , the scaling properties described by the local fractal dimension d and crossover length tc of 48 measured landform profiles in different direction of 6 different studied landform sections are calculated 負反饋機制表現(xiàn)的越明顯;對于以構造沉降作用為主的盆地區(qū)而言,各個方向的地形剖線的分維值均顯示出小于1 . 5的正反饋機制。
Long focus object lens of three color achromatic aberration is one of two posers of optical design , using this method can get a perfect result . compared with pw method , the first results received from the wave - deviation method are more accurate and more rapid 使用此數(shù)學模型編的光學自動設計程序,也可以說是光學鏡頭設計的一種新方法,即實現(xiàn)自動選玻璃,求解初始結構(曲率半徑r ,厚度d等)和自動校正像差和優(yōu)化系統(tǒng)等。
With deviation method employed , this paper analyzes quantitatively economic growth in 3 regions and 11 administrative areas in shanxi , and studies the contribution of the industrial structure and locational advantages to economic growth , and presents some feasible suggestions 摘要運用偏離份額分析方法對山西省三大地區(qū)以及11個地級市的經(jīng)濟增長進行了定量分析,從產(chǎn)業(yè)結構和區(qū)位因素兩方面計算其對經(jīng)濟增長的貢獻情況,并在此基礎上提出一些建議。
