We perform a systematic calculation of th. equation of state of asymmetric nuclear matter at finite temperature with.n th. framework of th. Brueckner-h.rtree-Fock approach.with.a microscopic th.ee-body force. Wh.n applying it to th. study of h.t kaon condensed matter, we find th.t th. th.rmal effect is more profound in comparison with.normal matter, in particular around th. th.esh.ld density. Also, th. increase of temperature makes th. equation of state sligh.ly stiffer th.ough.suppression of kaon condensation.

1984年约有12万吨聚氯乙烯加工成窗户型材,大致相同数量的聚氯乙烯挤出成诸如滑动百叶窗、电线槽板、房屋正面用型材等硬质聚氯乙烯型材。所有这些型材所用的稳定剂几乎都是用钡—镉或铅—钡—镉体系。但是有机锡化合物在型材和片材挤出中却没有上述这些稳定剂体系的作用那样大。相反,在薄膜、中空制品方面几乎毫无例外地都使用在生理上无害的有机锡化合物作稳定剂。为此本文将阐述有机锡稳定体系的优缺点及其在实际用途上的优越之处。

Noise measurements are especially a problem wh.n th. object under investigation is largely dimensioned and can only be measured from th. distance. To obtain information about th. location of noise generation, a measurement tech.ique wh.ch.makes sound visible in order to introduce furth.r specific tech.ical measures is advantageous. Th. question is if th. time dependence of th. signal got from such.a non touch.ng and non destructive acoustic meth.d h.s th. potential to calculate th. materials damping from. using a small sound source localization system （Microflown^TM probe）, specimens of magnesium alloys with.different grain sizes obtained by h.drostatic extrusion were investigated. It h.s been demonstrated th.t th. fine grained microstructure led to a lower damping and its dependence on th. strain was reduced. In th.s context, acoustic measurements by a sound source localisation system wh.ch.makes materials ch.racterization possible could be used as a quality tool to detect ch.nges in h.gh.y stressed components. Th.s approach.allows to promote a selective substitution of conventional materials by more innovative ones. Th. offsh.re sector is considered to be a field of application： Wind turbines produce noise emission wh.ch.stems mainly from turbulences at th. tips of th. rotor blades and vibrations of components inside th. nacelle （e.9. gearbox, generator, ...）. If th. vibration amplitudes are too h.gh. microcracks of components can lead to failure over th. long term. Th. monitoring of microstructural ch.nges using a larger type of a sound source localisation system is considered as an innovative tech.ical approach.with.respect to maintenance activities.

Th. effects of a h.rmonically exciting monopole source on an infinitely long cylindrical cavity embedded entirely with.n a fluid-saturated poroelastic formation of infinite extent are examined th.oretically. It is assumed th.t th. source is located outside th. cavity at a specified distance from th. boreh.le axis. Th. magnitudes of th. h.op and radial stresses beside th. pore pressures exerted on th. interface and inside th. porous medium surrounding th. boreh.le are calculated and discussed. Biot's poroelastic modeling along with.th.ee types of boundary conditions for th. cylindrical interface including th. ideal fluid, empty boreh.le, and rigid inclusion with.a h.rd boundary is employed for th. analysis. utilizing a proper translational addition th.orem for expressing th. incident sph.rical wave in terms of cylindrical wave expansions, th. proposed boundary conditions at th. interface are satisfied. Stresses are formulated by means of wave potential functions in a th.ee-dimensional(3D) manner. Th. effects of th. frequency and th. radial distance between th. source and boreh.le on th. induced stresses are examined for th. first cylindrical modes over frequency spectra. Two permeability conditions for th. interface and th.ee types of soils for th. porous formation are considered th.ough.ut th. analysis. To give an overall outline of th. study, a numerical example is presented. Th. results clearly indicate th.t th. distance is a key parameter and h.s considerable effects on th. induced stress values. In addition, th. interface permeability condition and soil ch.racteristics play an important role in determining th. dynamic response of th. boreh.le. Finally,th. obtained results are compared with.th. relevant analyses existing in th. literature for some limit cases, and good agreement is ach.eved.

In 1872, George h.ntington presented h.s essay “On Ch.rea” to th. Meigs and Mason Academy of Medicine and, in doing so, detailed a disease th.t would later bear h.s name. h.ntington's disease(h.) is a genetic, neurodegenerative disease th.t manifests as th. loss of motor control,cognitive impairment,and mood and psych.atric ch.nges in paents.

We exploit th. recoil loop measurements to study La0.07 Sr0.33 Mn O3/La0.33 Ca0.67 Mn O3 bilayer film. th. asymmetric magnetization reversal in an exch.nge-biased It is found th.t th. recoil curve encloses a marked area only in th. second quadrant of th. h.steresis loop, and th. recoil susceptibility in th. descending branch.of th. major loop is evidently h.gh.r th.n th.t in th. ascending branch. Th. study indicates th.t th. exch.nge anisotropy of a unidirectional nature and an orientation deviated from th. easy axis of th. ferromagnetic layer plays a crucial role in creating th. reversal asymmetry.
