We Construct and SU(1,1)coherent state for hydrogen,we discuss its properties,and we give the energy distribution law of the atom.The coherent state may be used to describe the atomic states of the discrete spectrum.     

Effect of Notoginsenoside-Rg1 on the Expression of Several Proteins in the Striatum of Rat Models with Parkinson＇s Disease

After establishing hemi-Parkinsonian rat models, the relationships between neuron death and the expression of several proteins, such as c-Fos, GFAP, GDNF, NF-κB and some cytokines were determined. Therapeutics experiments with notoginsenoside-Rg1 were carried out. The research results show that the expressions of GFAP, NF-Kκ and c-Fos will obviously increase in the lesion side of the striatum and the expression of GDNF will decrease, which implies that the signal transduction pathway may participate in the apoptosis in neurons. The levels of some cytokines such as TNF-α, IL-1β in the striatum of PD rat models increased compared to those of normal rats. The results of the therapeutics experiments show that notoginsenoside-Rg1 may repress the immune inflammation response and regulate the immune function through the neuro-immune molecular network. Therefore, notoginsenoside-Rg1 can be used as an effective drug for anti-oxidation and anti-inflammation, and can be used in the therapy of Parkinson＇s disease（PD）.

Segal－Bargmann－Hall Transform and Geometric Quantization

Using geometric methods, Hall has proved that the Segal-Bargmann transform for a con-nected Lie group K of compact type is an isometric isomorphism [H1] and is unique when Kis simply connected [H7]. Furthermore, Hall considered geometric quantization of T~*(K), K'scotangent bundle [H9]. Using the vertical polarization and a natural Khler polarization obtainedby identifying T~*(K) with the complexified group KC, Hall concluded that the pairing map be-tween the two Hilbert Spaces induced by these two polarizations coincides with the generalizedSegal-Bargmann transform C_t (up to constant).     

精密垫片精冲工艺有限元分析与模具设计

精密垫片零件，如图1所示，零件材料为1Cr18Ni9Ti，强度大（σb=650MPa），有一定塑性。从零件尺寸精度看，φ4mm外圆为IT7级精度，φ4mm外圆与φ2mm内孔有很高的同轴度要求，冲裁断面与零件两端面有垂直度要求，普通冲压不能达到零件精度：从工序的角度看，有冲孔和落料工序，剪切面粗糙度Ra≤3．2μm，属于光洁冲裁范畴；另外，技术条件中要求零件两大面不得有任何划伤，且光滑平整。总体上看，该零件的冲压加工性不好，难度较大，对模具的设计、选材、制造要求都较高。
