人們採用某常數作為指數函數中的底,這個常數是無理數。Wavelet discussed in this paper is a basis of l2 or other spaces created by a function ( mother wavelet ) expand and contract and shift
本文討論的小波是指由一個函數(母小波)經過伸縮與平移所產生的l ~ 2或其它空間的基底。In the analysis process, the six main peaks in 88 - 100 kev region, including the y peaks of 234th, the k peaks of th and the k peaks of u, are chosen. the smoothly joined gaussian function and low energy exponential tail is taken as peak shape function and quadratic polynomial is taken as background function. the two functions are fitted to gether to calculate the peak area
在分析過程中,選擇了88 - 100kev能區的~ ( 234 ) th的射線峰, th的k _射線峰以及u的k _射線峰共六個主要能峰,通過採用高斯函數和低能指數尾部光滑聯接的峰形函數和二次多項式本底函數一起擬合,來求出峰面積;而該能區所有能峰的探測效率可以認為是近似相等的,由此得到鈾富集度。
