A matrix-perturbation-theory-based optimal strategy for small-signal stability analysis of large-scale power grid被引量:1
《Protection and Control of Modern Power Systems》2018年第1期362-372,共11页Yude Yang Jixing Zhao Hui Liu Zhijun Qin Jun Deng Junjian Qi 
This work was supported by the National Natural Science Foundation of China(Grant No.51577085).
In this paper,a sensitivity matrix based approach is proposed to improve the minimum damping ratio.The proposed method also avoids burdensome deviation calculations of damping ratio of large-scale power grids when com...

Evolution of Shower Parton Distributions in a Jet from Quark Recombination Model
《Chinese Physics Letters》2006年第2期332-335,共4页谭志光 杨纯斌 
Supported in part by the National Natural Science Foundation of China uuder Grant No 10475032, and the Ministry of Education of ,China under Grant No 03113. C.B.Y would like to thank R. C. Hwa and X. N. Wang for stimulating discussions.
The evolution of shower parton distributions in a jet is investigated in the framework of a quark recombination model. The distributions are parameterized and the Q^2 dependence of the parameters is given by polynomia...

Remarks on Exact Solvability of Quantum Systems with Spatially Varying Effective Mass被引量:1
《Chinese Physics Letters》2005年第11期2742-2745,共4页B. Goenül M. Kocak 
Within the frame of a novel treatment we make a complete mathematical analysis of exactly solvable onedimensional quantum systems with non-constant mass, involving their ordering ambiguities. This work extends the res...
