This paper presents the principles of electrical logging,acoustic logging,radioactive logging and NMR(nuclear magnetic resonance)logging and establishes the
Spontaneous potential well-logging is one of the most common and useful well-logging techniques in petroleum exploitation.Based on a series of previous resu
This work solves the Schrӧdinger equation with superposed potential(IQYIQP)made up of inversely quadratic Yukawa(IQY)potential and inversely quadratic(IQ)p
I will consider a system of N interacting parallel edge dislocations in single-slip,and discuss the convergence of the evolution of the corresponding empiri
Since the 1950s,it has been understood that dislocations can arrange themselves into regular structures,and the analysis of these structures has been an imp
We consider the Lam′e system with partial infinity coefficients in dimension two which describes a model of a linear isotropic elastic body containing two
