The Extrap Concept .. is obtained by generating a plasma current . = curl../µ. along the zero-field region of the externally imposed transverse “vacuum” field ... Second, the field .. is strongly inhomogeneous which leads to a non-circular plasma cross section and to a stabilizing effect on a large class of free-boundary and internal modes.牌带来 发表于 2025-3-28 19:18:39
Lothar Papulafor investigating the crystallography and microstructure of surfaces and very thin films. Diffraction gives a statistical view of disorder rather than a local picture, as would be obtained, for example, in a scanning tunneling microscope. Many processes occurring at surfaces, such as growth, phase t
