Solid reactions between Ni and relaxed Si0.7Ge0.3 substrate were systematically investigated with different Al interlayer thicknesses. The morphology, composition, and micro-structure of the Ni germanosilicide layers were analyzed with different annealing temperatures in the appearance of Al. The germanosilicide layers were characterized by Rutherford backscattering spectrometry, cross-section transmission electron microscopy, scan transmission electron microscopy, and secondary ion mass spectroscopy. It was shown that the incorporation of Al improved the surface and interface morphology of the germanosilicide layers, enhanced the thermal stabilities, and retarded the Ni-rich germanosilicide phase to mono germanosilicide phase. With increasing annealing temperature, Al atoms distributed from the Ni/Si0.7Ge0.3 interface to the total layer of Ni2Si0.7Ge0.3, and finally accumulated at the surface of NiSi0.7Ge0.3. We found that under the assistance of Al atoms, the best quality Ni germanosilicide layer was achieved by annealing at 700？C in the case of 3 nm Al.

目的探讨足月顺产产妇盆底康复治疗的时机及其疗效,为预防和早期治疗盆底功能障碍性疾病(pelvic floor dysfunction,PFD)提供依据。方法选择2014年1月至2015年12月在福田区妇幼保健院产科门诊进行盆底康复治疗的1 000例产妇为研究对象。根据治疗时间分为A组和B组,每组各500例,A组于产后6~12周治疗,B组于产后12~20周治疗,共治疗10次,之后门诊定期随访,治疗3个月后再次评价盆底肌力。结果两组产妇治疗前均存在不同程度的盆底肌张力异常,但差异无统计学意义(P>0.05)。治疗后,A组和B组Ⅰ类肌纤维的持续收缩压、持续时间和Ⅱ类肌纤维的快速收缩压、收缩个数相比较,差异有统计学意义(P<0.05)。结论足月顺产后产妇均存在不同程度的盆底肌力异常,盆底康复治疗能改善盆底肌力,早期治疗更加有效,临床医生有必要指导产妇及早进行治疗。

Communications in Theoretical Physics 2006年第2X期46卷 348-352页

We study theoretically transport properties of two-dimenslonal electron gases through antiparallel magneticelectric barrier structures. Two kinds of magnetic barrier configurations are employed： one is that the strength of the double δ-functlon in opposite directions is equal and the other is that the strength is unequal Similarities and differences of electronic transports are presented. It is found that the transmission and the conductance depend strongly on the shape of the magnetic barrier and the height of the electric harrier. The results indicate that this system does not possess any spin filtering and spin polarization and electron gases can realize perfect resonant tunneling and wave-vector filtering properties. Moreover, the strength of the effect of the inhomogeneous magnetic field on the transport properties is discussed.
