bend contour造句

• In principle, one could therefore use this bend contour to model the foil's vector tilt ( with milliradian accuracy ) at all points across the oval.
• The [ 100 ] bend contour " spider " of this image, trapped in a region of silicon that was shaped like an oval watchglass less than a micrometre in size, was imaged with 300 keV electrons.
• Experimental and theoretical maps of Kikuchi band geometry, as well as their direct-space analogs e . g . bend contours, electron channeling patterns, and fringe visibility maps are increasingly useful tools in electron microscopy of crystalline and nanocrystalline materials.
• The contrast effects are to first order similar to those of bend contours, i . e . electrons which enter a crystalline surface under diffracting conditions tend to channel ( penetrate deeper into the specimen without losing energy ) and thus kick up fewer electrons near the entry surface for detection.
• These coherent scattering features include added diffraction ( responsible for bend contours in curved foils ), more electron penetration ( which gives rise to electron channeling patterns in scanning electron images of crystal surfaces ), and lattice fringe contrast ( which results in a dependence of lattice fringe intensity on beam orientation which is linked to specimen thickness ).
