目的比较3DT2加权快速自旋回波(TSE)与多平面2DT2加权TSE对于侵袭性子宫颈癌的评估。方法 75个子宫颈癌病人进行了3.0TmRI盆腔检查,均使用了5mm层厚的多平面2D(总时间为12min25s)以及1mm层厚的冠状位3DT2加权TSE序列扫描(7min20s)。对信噪比(SNR)进行定量分析,对影像质量进行定性分析。对45例接受根治性子宫切除术的病人进行了局部区域的分期。结果 3D成像中子宫颈癌的预估SNR及肿瘤相关的对比度显著增高(PmR数据采集,3DT2加权多平面重组影像在整体影像质量和子宫颈癌的分期准确度上大体相当于2DT2加权成像,但是对于肿瘤边缘的锐度显示还是有局限性。要点①对于子宫颈癌分期,3DT2加权序列等同于2DT2加权序列。②冠状位3D数据采集可以减少检查时间。③3D序列SNR和肿瘤相关的显著性明显更高。④3DT2加权重组影像对于肿瘤边缘的锐度显示不佳。

The effects of Ca and Sr addition on the microstructure and creep properties of mg-4Al-2Sn alloys were examined. Tensile tests at 25 ℃ and 200 ℃ and creep tests at 150 ℃ and 200 ℃ were carried out to estimate the room temperature and high temperature mechanical properties of these alloys. The microstrueture of the mg-4Al-2Sn alloy showed dendritic a-mg, mg17Al12 and mg2Sn phases. The latter two phases precipitated along the grain boundaries. The addition of Ca and Sr resulted in the formation of ternary CamgSn and SrmgSn phases within the grain. The grain size was reduced slightly with the addition of Sr and Ca. The tensile strength was decreased by the addition of Ca and Sr at room temperature. However, the high temperature tensile strength was increased. The creep strength was improved by the addition of Ca and Sr.

The microstructure and mechanical properties of mg-xCe-0.5Zn （x=0.5, 1.5, 2.5, molar fraction, %） alloys were examined using a nano-indentation technique. The alloys were fabricated using a vacuum induction melting method under an argon atmosphere The microstruetures of mg-xCe-0.5Zn alloys mainly consist ofa-mg and eutectic mg12Ce phase. The volume fraction and size of the eutectic mgl2Ce phase increase with increasing Ce contents. Nano-indentation test results show that the indentation hardness and elastic modulus of the eutectic mg12Ce phase are higher than those of the a-mg matrix. In addition, the mean indentation hardness and elastic modulus of the mg-xCe-0.5Zn alloys increase with the Ce addition amount increasing.

The deformation mechanisms and processing maps of the as-cast Al-Zn-mg-Cu （？0？5） aluminum （AI） alloy were studied and compared with those of the homogenized 7075 Al alloy in the temperature range of 573-723 K and in the strain rate range of 10 3-10 s-1 to explore a possibility for directly using the as- cast 7075 Al alloy as a billet for hot working. The as-cast and homogenized 7075 A1 alloys had similar grain sizes and showed similar high-temperature deformation behaviors. The as-cast 7075 Al alloy, however, exhibited higher power efficiencies and smaller unstable flow regions compared to the homogenized 7075 AI alloy because of the presence of secondary phases （mgZn2） segregated at the dendritic interfaces in the as-cast microstructure, which were formed during non-equilibrium solidification. These segregated phases provided nucleation sites for dynamic recovery or continuous dynamic recrystallization, and as a result a fine and more homogeneous （sub）grain structure could be obtained from the as-cast micro- structure compared to the homogenized microstructure. The current work suggested the possibility and advantage of using as-cast microstructures for hot working of aluminum alloys with high content of solutes.
