And conclude that the impulsively started cross flow analogy is not suit precisely to predict the sectional side force distribution of slender body with a pointed ogive nose, because the pointed nose slender body exhibit an roll angle effects.

认为脉冲起动横流比拟方法不适用于预测尖头拱形细长体的侧向力分布特性，因为尖头拱形细长体具有明显的滚转角效应。

Results: The proportional volume, numerical density of the granules in ovariotomy group were less than those in sham-ovariotomy and ovariotomy estradiol groups (P.001); the proportional volume and numerical density of ASG in myocardial cells almost came back to the normal level with small dose estradiol; along with the enhancement of estradiol dosage, the content of ASG in myocardial cells was more than those in sham-ovariotomy and small dose estradiol group (P.01), and showed a quantity-efficiency relation.

结果：切除大鼠双侧卵巢后，心房特殊颗粒的体密度和数密度与对照组及用雌二醇组比较明显减少(P＜0.01)，小剂量雌二醇可使大鼠心肌细胞心房特殊颗粒的体密度和数密度恢复到正常水平，随剂量增加，心肌细胞心房特殊颗粒的量也伴随增加，呈量效关系。

There was a high risk of thin cement mantle in Gruen zones 1,2 and 5 in the anteriorposterior plane and in Gruen zones 8,9 and 12 in the lateral plane.Typical areas of radiolucency were identified in Gruen zones 2～5 and 10～12 in the middledistal of the stem.Voids appeared in Gruen zones 3～5 and 10～12 in the distal of the stem.

结果(1)按Barrack标准，骨水泥质量A级87.1%，B级11.8%，C级1.1%，无D级骨水泥；(2)按Gruen分区，骨水泥鞘厚度 mm区域多见于正位片上1、2、5区和侧位片上8、9、12区；透亮带多位于假体中远端的2～5区和10～12区；气泡影出现在假体远端的3～5区和10～12区。

Typical areas of radiolucency were identified in Gruen zones 25 and 1012 in the middle-distal of the stem. Voids appeared in Gruen zones 35 and 1012 in the distal of the stem.

结果］(1)按Barrack标准，骨水泥质量A级87.1%，B级11.8%，C级1.1%，无D级骨水泥；(2)按Gruen分区，骨水泥鞘厚度＜2mm区域多见于正位片上1、2、5区和侧位片上8、9、12区；透亮带多位于假体中远端的2~5区和10~12区；气泡影出现在假体远端的3~5区和10~12区。

A divided B-spline surface model of shoe tree is founded, which offered the sound tree model for the shoemaking CAD/CAM. The calculating equation for control points of the bottom of the shoe tree is established for first time. A new method called LID to construct lateral and front surfaces of the shoe hell is proposed which furnishes the possibility for the hell CAD.

本文建立的楦体分块B样条曲面模型，为制鞋CAD/CAM提供了良好的楦体模型；首次建立并给出了楦底控制点计算方程和楦底分块Bezier曲面模型，奠定了鞋跟鞋底造型的基础；文中提出的设计鞋跟跟口面和跟侧面的LID方法，为鞋跟造型提供了实现可能性。

Using RT-PCR analysis, RGS7 was expressed from fertilization to 96 hours post-fertilization of Zebrafish. Expression of RGS7 was found in brain、aorta ventralis、intermediate cell mass and somite by whole-mount in situ hybridization.

因此，利用RT-PCR以及全胚体原位杂合技术，结果发现在受精后0~96小时的斑马鱼胚胎中皆可侦测到RGS7的表现，其表现的位置是在斑马鱼胚胎的脑部、腹侧主动脉、中期细胞团及体节等组织部位。

Fourteen porcine and 14 human thoracic functional spinal units with intact costotransverse and costovertebral articulations were used for biomechanical testing.

对标本在背侧方向和腹侧方向，在脊柱功能单元的上椎体正中矢状面中心加载剪切载荷，试验采用自动化光电子三维运动测量系统测量椎体旋转。

The screw entry point was located at the tip of transverse process. The average inclination angle should be 10°-20° headward and 30°-40° toward neutral line respectively. The screw was inserted and entered into the vertebral body along the external cortex of pedicle. The integrity of cortical bone around screws, the distance to segmental blood vessels and the penetration of cortex were observed after operation to evaluate the accuracy and safety of screw placement. Among 160 thoracic pedicle screws that were implanted in 34 cases, 148 screws (92.5%) were accurately inserted inside the costotransverse unit, and 12 screws (7.5%) were misplaced according to the image of X-ray and CT thin-slice scan.

应用椎弓根外内固定技术2004/2007年在中山大学附属第三医院骨科治疗34例患者，固定前采用CT加密扫描测量进钉点、进钉点至椎体前缘的深度、进钉角度和直径，固定中椎弓根钉入点为横突尖，进钉方向为平均向头侧倾斜10°~ 20°、与中线成角30°~40°，顺椎弓根外侧皮质进入椎体，固定后CT加密扫描观察螺钉周围的皮质骨是否完整、是否靠近节段血管、是否穿透皮质骨，评价置入钉的准确性和安全性。34例患者共置入160枚胸椎椎弓根螺钉，固定后CT加密扫描和X射线片观察到148枚(92.5%)螺钉置入准确，12枚(7.5%)螺钉发生错置。

ConclusionOne-stage posterior hemivertebrae and osseous divide resection combined with transpedicular instrumentation and bone graft can achieve a satisfactory result for the treatment of scoliosis of thoracic hemivertebra and diastematomyelia of adolescent.It can be recommended in clinical practice because of a good stability of fixation and fine spinal fusion.

结论一期后路半椎体及骨嵴切除、椎弓根螺钉内固定植骨融合术是治疗青少年胸椎半椎体脊柱侧凸合并脊髓纵裂的有效方法，具有较好植骨融合和稳定性，值得推广应用。

Furthermore, abundant hydrocarbon enriches in high quality sand-body traps by lateral confluence pathway in digitiform sand and fault vertical confluence pathway.

此外，存在汇流通道是油气富集的重要因素，充足的油气通过指状砂体侧向汇流通道和断层垂向汇流通道运移，在优质的砂岩体圈闭中聚集成藏。

I will endeavour to find you some assistance.
