The contact angle, as a vital measured parameter of wettability material surface, has long been in dispute whether it is affected by gravity. Herein, we the advancing and receding angles on extremely low angle hysteresis surfaces under different gravities (1-8G) found that both them decrease with increase underlying mechanism revealed to be deformation liquid-vapor interface away from solid surface caused gradient distribution hydrostatic pressure. real not gravity cannot an optical method....
The study of the secondary electron composition contrast imaging method have been developed with a conventional scanning microscope (SEM) equipped ultra-thin window energy dispersive X-ray spectrometer (EDS). On basis principle emission, has investigated, and ranges its application were also discussed. This was applied in microstructure studies on cathode materials TWT (traveling wave tube). results showed that, compared backscattered image, image could reveal well certain conditions....
It is shown that the relationship between mass attenuation coefficients and incoherent scattering radiation not an inverse proportion but a power function over wide range of atomic numbers (e.g. 5B–40Zr H3BO3–KBr). The experimental results are in good agreement with this theoretical prediction. A new method recommended for matrix absorption correction x-ray fluorescence analysis using Rh Kα Compton peak intensity. has been experimentally proved to be correct superior traditional internal...
A panoramic annular lens optical system is important in circumferential detection. However, a image (PAI) has severe tangential and radial distortion. This study proposes 3σ guideline-based method, which determines the unwrapping center point of PAI, prediction method based on design characteristics according to intrinsic distortion PAL correct, respectively, The proposed methods can ensure restoration ability simplify dependence experimental conditions. results confirm effectiveness thus...
Abstract. Uncertainty modelling is regarded as one of the core components in field urban navigation, that can affect performance indoor and outdoor location information acquisition, especially under obscured scenarios. Existing multi-source fusion-based seamless positioning algorithms are subjected to random highly dynamic human motion characteristics changeable observation errors caused by occlusions buildings scenes, which lead insufficient spatiotemporal correlation poor accuracy final...
It is demonstrated that the mass attenuation coefficient not linearly related to inverse intensity of continuous scattered radiation as assumed in scattering internal standard method. A power function relationship between absorption and scatter over more than a limited range matrix composition predicted theoretically supported by experimental results. As an example application method it was applied determination trace Sr geological samples. The accuracy this much better traditional technique...
Aimed at crack die problem of micro-package, a series experiments on failure components were conducted by using optical microscope, scanning electron microscope (SEM), Fein focus X-ray, cross section and various chemical etched methods. The analysis technique cracked in microelement was presented detail, the cause these found finally. Wafer processing defect has proven to be contributing factor cracking die. Mechanical damage acted as stress riser from which may propagate. root this...
