According to the concept of linear - fitting correction , the correction factors for correcting the test - piece image are obtained by reference images and their corresponding means captured at fixed tube voltage and different tube current
此方法基于线性拟合校正的思想，在一定管电压下，改变管电流采集一组探测器基准图像，利用这组图像与其相应均值进行拟合，再把拟合系数作为校正因子对试件成像进行校正。
Abstract : the maximum tube distribution numbers in tube sheet limited circle for fixed tube sheet heatexchanger have been determinded by used of the superposition method with computer based on c language programming . it is characterized by determination the maximum tube distribution number according to the even number or singular number of center tube distribution . the method is simply and quickly , and can be used for the design and process calculation of heatexchangers
文摘:采用迭加的方法，使用c语言编程在微机上实现管板布管限定圆最大布管数的确定.该方法可根据中心布管数是奇排列还是偶排列来确定最大布管数，简便易行，计算速度快，对换热器的设计及工艺计算具有实用价值
