测量了二十种金属元素的符合多普勒展宽谱,并与理论计算的结果比较.CDB谱的高动量部分反映了正电子与核心电子的湮灭,由于核心电子在原子组成材料时仍然保留了元素特性,CDB谱的高动量部分可以用来鉴别元素.

A NOTE ON THE EXISTENCE AND NONEXISTENCE OF GLOBALLY BOUNDED CLASSICAL SOLUTIONS FOR NONISENTROPIC G
Existence of globally bounded classical solution for nonisentropic gas dynamics system has long been studied, especially in the case of polytropic gas. In [4],

The characteristic time τD for decoherence process of a quantum nonlinear oscillator system under a nonzero temperature thermal bath is studied by expanding th
A new copper(II) complex, [Cu(BMI)4(SO4)]·DMF·2H2O (BMI = benzimida- zole), has been synthesized by the treatment of CuCN with 2-mercaptobenzimidazole in the
Global classical solutions near Maxwellians are constructed for the Boltzmann equation in a periodic box with angular soft cutoff, that is, -3 ＜γ＜ 0. The constru
The Study on the Noncovalent Complexes of Silver Ion with Xanthone Diglycosides by Electrospray Ioni
The silver ionic complexes of xanthone glycosides were studied by ESI-MS/MS in the positive ion mode. The fragmentation pathways of silver ionic complexes under
