At present, he is a reviewer of foreign SCI mathematical journals AML, CAM, MIA and JIA. In recent years, more than 60 papers have been published in academic journals such as AML, CAM, MIA, JIA and AAA at home and abroad, including 36 papers retrieved by SCI. From Ehrlich and I.Gargantini to Wang Xinghua and Zheng Shiming, the research on the convergence of the disk iterative quasi-Newton method has achieved fruitful results. Zhu Ling obtained the initial conditions for the iterative convergence of a single zero-point two-step disk and a complex zero-point one-step disk. The former is not involved, and the latter is the best result so far. The article on the initial conditions of two-step disc iterative convergence of quasi-Newton method ranked 10 in the Top25 of SCI magazine CAM in the fourth quarter of 2005, and rose to the fourth place in the first quarter of 2006. E. Durand, I. O. Kerner, I. Gargantini, P. Henrici, Wang Xinghua, Zheng Shiming and others have done a lot of work on the disc iterative convergence of Durand-Kerner method. And the results have been very rich. Zhu Ling solved the initial condition of multi-step disc iterative convergence of Durand-Kerner method in one fell swoop; In addition, the research on triangle inequalities such as Jordan, Redheffer, Wilker and Shafer-Fink inequality has always been in the leading position in the world. Particularly striking is the first application of monotone Robida's rule to the promotion of Jordan's inequality, and three papers in this field are widely cited as basic documents. This paper has been cited many times by 100.
