Under the condition of the borehole and sandstone formation filling with oil and water, respectively, the ability is different when different energy windows are selected to distinguish formation by simulating the detector response spectrum of various diameters and length of NaI and BGO crystal. The C/O value difference of BGO crystal is higher than that of NaI crystal when the energy window includes photoelectric peak, the first and the second escape peaks, but it is less affected by the different sizes of detector crystal. Using photoelectric peak corresponding to the energy window, the C/O value difference of BGO crystal detector is much larger than that of NaI, but it increases with the crystal size increasing. The C/O value is greatly affected by energy drifting, while relatively a little by energy resolution.

In this project, we study the theory of higher order differential equations in Banach spaces and related topics. We solve an open problem put forward by two American Mathematicians and two Italian Mathematicians concerning wave equations with generalized Weztzell boundary conditions, introduce an existence family of operators from a Banach space $Y$ to $X$ for the Cauchy problem for higher order differential equations in a Banach space $X$, establish a sufficient and necessary condition ensuring $ACP_n$ possesses an exponentially bounded existence family, as well as some basic results in a quite general setting about the existence and continuous dependence on initial data of the solutions of $ACP_n$ and $IACP_n$. We set up quite a few multiplicative and additive perturbation theorems for existence families governing a wide class of higher order differential equations, regularized cosine operator families, regularized semigroups, and solution operators of Volterra integral equations, obtain classical and strict solutions having optimal regularity for the inhomogeneous nonautonomous heat equations with generalized Wentzell boundary conditions, gain novel existence and uniqueness theorems,which extend essentially the existing results, for mild and classical solutions of nonlocal Cauchy problems for semilinear evolution equations, present a new theorem with regard to the boundary feedback stabilization of a hybrid system composed of a viscoelastic thin plate with one part of its edge clamped and the rest-free part attached to a visocelastic rigid body. Also we obtain many other research results.
