gravitational lensing: stronggalaxies: clusters: generalThe accuracy of mass estimates by gravitational lensing using the thin-lens approximation applied to NavarroFrenkWhite mass models with a soft truncation mechanism recently proposed by Baltz, Marshall and Oguri is studied. The gravitational lens ...

The thin lens equation is an equation that locates the image of a given object formed when it is placed in front of a lens. The "thin" part of a thin lens is an approximation that ignores almost all of the lens' properties...
Using the thin lens approximation and imaging formulat ion,the relations between the first-order ghost image and the focal length of a ll kinds of lenses are derived,which provides guidance for the design of lens in the high power laser facility. 为了得到一阶鬼点形成的一般规律,从成像公式出...
A monochromatic Al K-Alpha X-ray source type radiation with a spot size of 500.00 µm, standard lens mode, analyzer pass energy of 20.00 eV and step size of 0.05 eV were used to characterize La, Co and O based on different acquired time. Deconvolution was performed by Fityk software ...
The focusing element (lens) 27 is at a focusing distance L1 from the specimen. The focused light beam 29 reaches the spot diameter δ at the point of reflection. The diameter of the specularly reflected light beam 30 reaches the value d' at the distance L2 from the specimen 26 to the ...
Designing efficient Ruthenium-based catalysts as practical anodes is of critical importance in proton exchange membrane water electrolysis. Here, we develop a self-assembly technique to synthesize 1 nm-thick rutile-structured high-entropy oxides (RuIr
Equation (1) thus describes a material in its relaxed state. The photomechanical coefficients will be different in an initially stressed material, but we will assume that all pre-stress due to sample mounting will be small enough to ignore this effect. When 𝜅(𝑛)𝜎κσ(n)> 0, light...
The dependence of phase formation and mechanical properties on the chemical composition has been investigated for Pt-Ir and Pt-Au combinatorial thin films. The formation of a single, metastable Pt-Ir solid solution has been observed for all experimental
