AbstractObjectives1 Correlate bone mineral densityto vertebral compressive strengths.2 Consummate the technique for percutaneous polymethylmethacrylate vertebroplasty and observe the pattern of PMMA imaging distribution.3 Determine the strength and stiffness of osteoporotic with or without vertebroplasty with PMMA bone cement.4 Correlation of BMD,insertion torque and pull-out strengths of pedicle screws.5 Ascertain whether augmentation with PMMA bone cement can enhance pedicle screw fixation in the osteoporotic spine.6 Ascertain whether augmentation pedicle screw fixation with PMMA bone cement can enhance the stability of unstable thoracolurner burst fractures of osteoporotic spine.

目 的1、测试椎体压缩强度，分析强度与骨矿物质密度（bone mineral density，BMD）的相关关系。2、观察经皮椎体成形术后聚甲基丙烯酸甲脂（polymethylme- thacrylate，PMMA）骨水泥在椎体内的形态学分布及影像学表现。3、比较PMMA骨水泥骨质疏松椎体成形术前/后椎体最大抗压力和压缩刚度的变化。4、分析椎体BMD、螺钉最大旅入力矩和最大拔出力三者之间的关系。5、分析PMMA骨水泥强化骨质疏松椎弓根螺钉后的螺钉的最大轴向拔出力和拔出刚度的变化。6、评价PMMA骨水泥强化骨质疏松椎弓根螺钉脊柱内固定对不稳定型胸腰椎损伤的即刻稳定性和反复载荷后的稳定性。

But due to significant magnetic flux leakage present in the loosely wound embedded solenoid inductor structure, large inductance cannot be realized in a compact structure. This is followed by the design of a LTCC common-mode filter intended for use with USB 2.0 products. As compared to the wire-wound common-mode choke, the designed multi-layer common-mode filter produces lower insertion loss on differential-mode signal than conventional ferrite-based common-mode filter.

接著讨论利用低温共烧陶瓷制程技术，设计应用於USB 2.0产品的共模滤波器，相较於一般以磁性材料为主的绕线式共模滤波器，使用多层电路技术设计的共模滤波器可提供较低的差模讯号损失，此外，应用偏移线路的新架构而非完全重叠的线路来设计差模讯号线路组，可减少33%的零件厚度。

Mitochondrial cytochrome b sequence were used to study the molecular evolution and phylogeny of Anser cygnoides(15 breed of Chinese goose), Anser anser(2 breed of domestic European goose) and Anser albifrons(the lesser white-fronted goose, Genbank accession number AF363031). Sequence analysis revealed that there were 29 variable sites and 4 haplotypes in 45 sequences, nucleotide diversity and haplotype diversity were 0.0068,0.45 respectively, insertion/deletion or frameshift mutation were not found in Cyt-b gene sequences(1143bp).

本实验测定了中国家鹅15个品种、欧洲鹅2个品种共44个个体的细胞色素b基因全序列，与Genbank库中自额雁细胞色素b基因序列合并在一起比对分析，17个家鹅品种和白额雁细胞色素b基因全序列均为1143bp，序列中没有缺失、插入或移码突变，共检测到29个变异位点、4种单倍型，核苷酸多样度和单倍型多样度分别为0.00648和0.45。

In addition, plant/T-DNA junction sequence analysis excluded the possibility that insertion of T-DNA into anthocyanin genes had inactivated the anthocyanin biosynthetic pathway in white-flowered tobacco plants.

此外，植物/T-DNA接合序列分析亦排除产生白色花色的原因是由於T-DNA插入植物色素合成相关基因导致该基因丧失活性的可能性。

Based on the deep foundation pit project of tunnel in Nanjing metro west extending line, the supporting methods of the bored pile biting into deep mixing pile in soft soil are discussed. The key construction techniques and monitoring results for the supporting form in watered and soft soil bed are expounded. The ability of resisting seepage must be considered when insertion depth of supporting structure is designed, which may also prevent the skirting from losing its stability.
