An Optimal Volume Growth Estimate for Noncollapsed Steady Gradient Ricci Solitons
《Peking Mathematical Journal》2023年第2期353-364,共12页Richard H.Bamler Pak-Yeung Chan Zilu Ma Yongjia Zhang 
R.H.Bamler was supported by NSF Grant DMS-1906500;Y.Zhang was supported by the starting-up grant of Shanghai Jiao Tong University.
In this paper,we prove a volume growth estimate for steady gradient Ricci solitons with bounded Nash entropy.We show that such a steady gradient Ricci soliton has volume growth rate no smaller than r^n+1\2.This result...

State Estimation Approach for Combined Heat and Electric Networks被引量:1
《CSEE Journal of Power and Energy Systems》2022年第1期225-237,共13页Tongtian Sheng Guanxiong Yin Bin Wang Qinglai Guo Jinni Dong Hongbin Sun Zhaoguang Pan 
This work was supported in part by the National Natural Science Foundation of China(61733010);the China Postdoctoral Science Foundation(2019M650675).
State estimation(SE)is essential for combined heat and electric networks(CHENs)to provide a global and selfconsistent solution for multi-energy flow analysis.This paper proposes an SE approach for CHEN based on steady...

On the energy conservation and critical velocities for the propagation of a "steady-shock" wave in a bar made of cellular material被引量:8
《Acta Mechanica Sinica》2013年第3期420-428,共9页Li-Li Wang Li-Ming Yang Yuan-Yuan Ding 
supported by the National Natural Science Foundation of China (11032001);the K.C.Wong Magna Fund in Ningbo University
The propagation of shock waves in a cellular bar is systematically studied in the framework of continuum solids by adopting two idealized material models, viz. the dynamic rigid, perfectly plastic, locking (D-R-PP-L...

Wheat breeding model for steady and high yield and early maturation in middle and south Hebei province —Analysis of steady and high yield ability of wheat variety Ji 84-5418
《华北农学报》1994年第S2期38-44,共7页武金铭 刘洪岭 
A wheat breeding model for high yield in the middle and south of Hebei Province was developed. Wheat variety Ji 84-5418 has been bred on this model. The analysis results of high-yield and stability indicated that Ji 8...
