Hannay＇s angle is a classical analogue of the ＂geometrical phase factor＂ found by Berry in his research on the quantum adiabatic theorem. This classical analogue is defined if closed curves of constant action variables return to the same curves in phase space after an adaibatic evolution. Adiabatic evolution of Yang-Mills cosmology, which is described by a time-dependent quartic oscillator, is investigated. Phase properties of the Yang-Mills fields are analyzed and the corresponding Hannay＇s angle is derived from a rigorous evaluation. The obtained Hannay＇s angle shift is represented in terms of several observable parameters associated with such an angle shift. The time evolution of Hannay＇s angle in Yang-Mills cosmology is examined from an illustration plotted on the basis of numerical evaluation,and its physical nature is addressed. Hannay＇s angle, together with its quantum counterpart Berry＇s phase, plays a pivotal role in conceptual understanding of several cosmological problems and indeed can be used as a supplementary probe for cosmic inflation.

马来半岛广泛发育的晚古生代‒早中生代岩浆作用完整地记录了古特提斯洋俯冲‒碰撞‒消亡的演化历史。该洋盆于中‒晚三叠世关闭,随之发生陆‒陆碰撞、地壳增厚以及造山带垮塌,区域上形成大规模的碰撞后火成岩,构成了东南亚古特提斯巨型火成岩带东部和中部花岗岩省的重要组成部分,但关于其岩石成因及构造背景仍然存在不同认识。因此,本文对马来半岛东部晚三叠世花岗岩开展了详细的岩相学、年代学以及地球化学研究,并结合区域地质资料综合探讨了晚三叠世岩浆作用的演化规律及深部动力学过程。研究表明马来半岛东部晚三叠世花岗岩可以分成两组:第一组为231~222 Ma,样品显示出较为富集的同位素特征((^(87)Sr/^(86)Sr)i=0.72040~0.72518,εNd(t)=−10.4~−6.7,εHf(t)=−11.5~+0.1),来自变火成岩和变杂砂岩的混合源区;第二组样品形成于218~216 Ma,对应的(^(87)Sr/^(86)Sr)i=0.70576~0.71464,εNd(t)=−9.1~−3.9,εHf(t)=−3.9~+1.9,表明其源区存在一定新生地壳物质的参与,且Ga/Al、FeO^(T)/(FeO^(T)+MgO)值及锆石饱和温度相对较高,具有典型的A型花岗岩特征。年代学结果表明古特提斯东部和中部花岗岩省晚三叠世岩浆作用的峰期为220 Ma,且具有相似的元素‒同位素变化规律,证实古特提斯洋碰撞后造山垮塌主要发生于220 Ma,软流圈上涌促使中‒下地壳物质发生部分熔融从而形成了区域大规模的岩浆作用。

Invariant operator method for discrete or continuous spectrum eigenvalue and unitary transformation approach are employed to study the two-dimensional time-dependent Pauli equation in presence of the Aharonov-Bohm effect （AB） and external scalar potential. For the spin particles the problem with the magnetic field is that it introduces a singularity into wave equation at the origin. A physical motivation is to replace the zero radius flux tube by one of radius R, with the additional condition that the magnetic field be confined to the surface of the tube, and then taking the limit R → 0 at the end of the computations. We point that the invariant operator must contain the step function θ（r - R）. Consequently, the problem becomes more complicated. In order to avoid this dimculty, we replace the radius R by ρ（t）R, where ρ（t） is a positive time-dependent function. Then at the end of calculations we take the limit R →0. The qualitative properties for the invariant operator spectrum are described separately for the different values of the parameter C appearing in the nonlinear auxiliary equation satisfied by p（t）, i.e., C 〉 0, C = 0, and C 〈0. Following the C＇s values the spectrum of quantum states is discrete （C 〉 0） or continuous （C ≤ 0）.

The aim of this work is to study the influence of successive weld repairs on the microstructure and the mechanical behavior of the heat-affected zone（HAZ） of an HSLA X70 steel. Detailed microstructural examination combined to grain size measurement showed that beyond the second weld repair, the microstructure of the HAZ undergoes significant change in the grain morphology and grain growth. The results of the X-ray diffraction analyzed using MAUD software indicated an increase in the crystallite size and a decrease in the dislocation density according to the number of weld repair operations. Consequently, a loss of mechanical properties, namely the yield strength and the toughness with the number of weld repairs, was recorded. Beyond the second weld repair operation, the properties of the welded joint do not fulfill the standards applied in piping industry.

We derive, with an invariant operator method and unitary transformation approach, that the Schr6dinger equation with a time-dependent linear potential possesses an infinite string of shape-preseving wave-packet states 1φ,λ （t） having classical motion. The qualitative properties of the invariant eigenvalue spectrum （discrete or continuous） are described separately for the different values of the frequency ω of a harmonic oscillator. It is also shown that, for a discrete eigenvalue spectrum, the states 1φ,λ （t） could be obtained from the coherent state 1φ,λ （t）.
