For the first time we derive the dissipating result of an initial two-mode squeezed pure vacuum state passing through a two-mode amplitude dissipative channel described by the direct product of two independent single-mode master equations. Although these two master equations do not mix the two modes （there is no coupling between them）, since the two-mode squeezed state is simultaneously an entangled state, the final state which emerges from passing this channel is a two-mode mixed density operator. The compact expression of the outcoming state is obtained, which manifestly shows that as time evolves, the squeezing effect decreases.

A coordination polymer [Mn2（ctpt）2（aic）2]n （1, ctpt = 2-（4-chloro-phenyl）-1H- 1,3,7,8-tetraaza-cyclopenta[l]phenanthrene, H2aic = 5-amino-isophthalic acid） was hydrother- mally designed and synthesized. The complex was characterized by elemental analysis, IR spectro- scopy, single-crystal X-ray diffraction, and thermogravimetric analysis （TGA）. Each Mn（II） atom is linked by the aic ligands with neighbor Mn（II） atoms, forming an infinite one-dimensional （1D） double-chain structure. Complex 1 crystallizes in monoclinic, space group C2/c, with a = 18.23（1）, b = 17.27（1）, c = 16.69（1）？, V = 4814.0（7）？3, C27H16ClMnN5O4, Mr = 564.84, Dc = 1.559 g/cm3, μ（MoKα） = 0.706 mm-1, F（000） = 2296, Z = 8, the final R = 0.0487 and wR = 0.1269 （I 〉 2σ（I））. The 1D chain structure of complex 1 is stable below 458 ℃. In addition, to elucidate the essential electronic characters of this complex, theoretical calculation analysis of 1 was performed by the PBE0/LANL2DZ method in Gaussian 03 Program.

We have theoretically studied the mobility limited by interface roughness scattering on two-dimensional electrons gas（2DEG） at a single heterointerface（triangle-shaped quantum well）.Our results indicate that,like the interface roughness scattering in a square quantum well,the roughness scattering at the Al_xGa_（1-x）As/GaAs heterointerface can be characterized by parameters of roughness height A and lateral A,and in addition by electric field F.A comparison of two mobilities limited by the interface roughness scattering between the present result and a square well in the same condition is given.

Different cultural subjects have different cultural and historical background, and thus inevitably bring difference in people's ideological values and behaviors etc,and even shocks. T oday,cross - cultural adaptation becomes a common social issue,and arouses general concern of the whole society. Influencing factors of cross - cultural adaptation include cultural distance,personality psychology,thinking pattern,values,social living environment,social support,know ledge & skills,pragmatic transfer etc. Based on making clear the problems,cross - cultural adaptation should be realized from multiple aspects.

English teachers mainly pass on knowledge through teacher talk in China. This paper focuses on the analysis of characteristics of teacher talk and discusses some ways to make teacher talk more comprehensible for learners' input. It has been concluded that with conscious improvement or exploration on teacher talk in practice, teachers can greatly enhance their teacher talk and make an effective combination between teacher talk and comprehensible input.

The novel, By the light of my father＇s smile, is the book which comprehensively embodies Alice Walker＇s womanist thoughts. In the novel, she describes a mixed tribe with both African and Indian ancestry. Through the mundo tribe with African features, she expresses her thoughts of Afracentrism. First of all, Alice Walker holds that African Americans should cherish the traditional African indigenous religion-animism, for it promotes equality and interrelateness among things. Furthermore, through Mundo people＇s cultural activities of making pots and their initiation songs, she intends to express such a womanist idea that survival and wholeness of entire race derives from that of each race, so those indigenous people who have been overrun by the powerful and wealthy western world are supposed to forgive the westerners＇ wrong doings, for only love can guide the entire race to achieve survival and wholeness.
