1用动测法预测桩的承载力显示文摘本文介绍一种根据应力波理论预测桩的动承载力的新方法。有关测量桩侧及极端阻力的应用方法及理论根据也分别予以讨论。虽然CASE法和CAFWAP分析法已广泛应用于预测桩的承载力,但并未考虑桩的频率特牲。由于锤击力的频率和桩的反射波频率彼此存在很大的差异,在打桩过程中用CASE法难以预测土的阻力。将桩的响应频率低的同样测量频率用于入射波和反射波,以预测打桩时上的阻力。结果发现,本文所述方法与CAPWAP分析法预测的承载力几乎相等。N.Kawabata T.Sakai S.Kondo H.Kanai Y.Kobayashi T.Oki S.Nishimura 林晓玲 1992土工基础1992,,A10:0
2Study of Proton Resonances in ^(22)Mg by Resonant Elastic Scattering of ^(21)Na+p and Its Astrophysical Implication in ^(18)Ne(α,p) ^(21)Na Reaction Rate显示文摘Proton resonant states in 22Mg have been investigated by the resonant elastic scattering of 21Na+p. The 21Na beam with a mean energy of 4.00 MeV/u was separated by the CNS radioactive ion beam separator(CRIB) and bombarded a thick(CH2)n target. The energy spectra of recoiled protons were measured at scattering angles of θcm ≈172° and 146°,respectively. A new state at 7.06 MeV has been observed clearly and another new one at 7.28 MeV is tentatively identified due to its low statistics. The proton resonant parameters were deduced from an R-matrix analysis of the differential cross section data. The astrophysical resonant reaction rate for the 18Ne(α,p)21Na reaction has been estimated,and it is about five times larger than that assumed before.S.Kubono T.Teranishi M.Notani H.Baba S.Nishimura J.Y.Moon M.Nishimura S.Michimasa H.Iwasaki Y.Yanagisawa N.Hokoiwa M.Kibe J.H.Lee S.Kato Y.Gono C.S.Lee 2009原子核物理评论2009,26,S1:0
