摘要
对超导磁体系统中CICC导体进行数字模拟时,发现某些有用的图像曲线,可利用最小二乘法原理,对图像内容进行选择、修改、锐化处理,二值化后获得图像中曲线的函数表达式,即CICC稳定性与氦流量之间的量化关系。同时对拟合的函数曲线和原曲线比较,发现二者基本吻合,因此用最小二乘法来研究图像中曲线拟合构成的函数,是非常有用的方法。
Some useful image waves are found during the simulation of CICC in superconducting magnets system. Based on the method of least squares, the content of the image is selected, modified and sharpened. The expression of function of curve, the quantitative relation be- tween stability of CICC and flux of helium, is obtained with binaryzation. The fitting outcome is compared with the original curve. The result shows that it is useful to study the function of curve fitting with the method of least squares.
