In allusion to these problems, a plasma sheath model in an oblique magnetic field, which has one dimension coordinate space and three dimensions speed space, has been build. 273. The reason a mobile controller station was set up in the first place is that the magnetic flux around the Montes Volans interferes with the link signal from Hell's Gate. They need to be closer. 274. This paper discusses the existence of the magnetic monopole, the conclusion of which is that the magnetic monopole does not exist in the material world but exists in the hypothetical vacuum world. 275. One of the effective ways to improve the area recording density of magnetic media has been to reduce the size of recording unit. 276. Developing new type of magnetic recording media is most important for the recording density of magnetic recording to keep its speed of increasing. 277. It is an effective way register electroencephalograph ( EEG ) to magnetic resonance image ( MRI ) in functional brain imaging. 278. The divergence factor, magnetic field direction and phase difference were educed. The far-field scattering was solved with physical optics integration at the final reflection point. 279. The conventional demagnetizing method is not good at inner demagnetization using direct or alternating magnetic field. 280. The magnetic fluid sealing pressure is mainly related to the magnetic flux density of the magnetic gap, and also related to the structure. 281. To unify the magnetic field level of the whole area in marine geomagnetism surveying, the base value of the secondary base station must be reduced to the main base value. 282. A coupled magnetic - circuit - fluid thermal finite element model is proposed for thermal analysis of dry - type air-core reactor. 283. Field properties of magnetic quadrupole lenses and electron beam transport are studied in this paper. 284. The finish oil content of PET filament was measured by nuclear magnetic resonance spectroscopy. The application of this analysis method in production process was discussed preliminarily. 285. The reaction rate of non-leptonic quark weak interaction and the bulk viscosity of quark matter in the magnetic field are investigated. 286. When strain waves pass through a ferromagnetic bar, owing to piezomagnetic effect,[http:///magnetic.html] a nonuniform magnetic current will be stimulated by the strain wave simultaneously. 287.
