赖氨酸对儿童身心发育有显著影响。本文在此基础上,对年龄因素作进一步检验,运用方差分析的方法,改进方差分析中的某些计算,得出“不服用赖氨酸的儿童各年龄段之间在身心发育上无显著差异,同服赖氨酸的儿童各年龄之间有显著差异。”并得到赖氨酸最佳补给期。 相似文献

A trust region-CG algorithm for deblurring problem in atmospheric image reconstruction 总被引:3,自引:0,他引:3
In this paper we solve large scale ill-posed problems, particularly the image restoration problem in atmospheric imaging sciences,
by a trust region-CG algorithm. Image restoration involves the removal or minimization of degradation (blur, clutter, noise,
etc.) in an image using a priori knowledge about the degradation phenomena. Our basic technique is the so-called trust region
method, while the subproblem is solved by the truncated conjugate gradient method, which has been well developed for well-posed
problems. The trust region method, due to its robustness in global convergence, seems to be a promising way to deal with ill-posed
problems. 相似文献
