Detecting thin layer by using different seismic geophones and special processing technique at an archaeological site in southeastern China

Lizan, A.; Tian, G.; Wang, Y.; Chen, R.; Ali, S.; Liu, H. (Геофизический журнал, 2015)

The properties of geophones are important factors for high-resolution seismic exploration and have great influence on data quality. In this study we will address the problems of ultra- shallow seismic data acquisition and ...
Effect of Si and Mn on Microstructure and Mechanical Properties of Vacuum Suction Casting Al–4.5Cu Alloy

He, T.; Liu, H.; Shi, X.; Huo, Y.; Li, M.; Pan, T. (Проблемы прочности, 2018)

The high performance of alloys is dependent on microstructure, while alloying elements have significant influence on microstructure. In order to study the effect of Si and Mn elements on the microstructure and mechanical ...
Fracture Assessment of the Weld–Base Metal Interface of High-Strength Steel Weld Joint

Zhong, Z.P.; Liu, H.; Ma, J.J. (Проблемы прочности, 2018)

The brittle fracture of the weld joint at low stresses is controlled by high-strength steel characteristics and welding defects. Based on fracture mechanics, the fracture behavior of the weldbase metal interface of a ...
On the Gauss sums and generalized Bernoulli numbers

Gao, J.; Liu, H. (Український математичний журнал, 2012)

Using the properties of primitive characters, Gauss sums, and the Ramanujan sum, we study two hybrid mean values of Gauss sums and generalized Bernoulli numbers and give two asymptotic formulas.
