查询词典 external diameter

According to Biot-Savart law, the magnetic induction at the diameter position of the spin axis is calculated. Furthermore, using the internal and external radius of the Earth's outer core as well as the radius of the Earth and the magnetic induction at the Earth's magnetic pole, the volume charge density and surface charge density of the Earth's outer core have been obtained.

METHODS: The 15 hybrid dogs were randomly divided into 2 groups. In the experimental group (n=9), a hole was drilled at the slope beneath the tibial plateau to reach the medullary cavity. The cavity was enlarged by an appropriate drill to confirm the size of the cavity. The absorbable polyamide intramedullary rods were inserted from the hole in tibial superior extremity, and the fracture was anatomically reduced with the rod passing through the fracture. Two locking nails, which were cylinder polyamide rods, were respectively located 2 cm from the cutting site, in the distal and proximal ends. Auxiliary plaster external fixation was performed for 4 weeks. In the control group (n=6), quincunx intramedullary nails of the same diameter with 4 pre-drilled holes were accordingly inserted into the cutting segment, and 2 screws were locked in the distal and proximal ends, respectively.

The coupling could make the washing machine change the work state between washing mode and dehydrating mode. Synchromesh gear that is located on the flange section and connection gear that is located at the external circle surface of the down side of the flange section is formed on coupling. The compression spring is installed on the top of the coupling and effects to the coupling to make it always moving downward. The feature is diameter of the terminal section of the compression spring is smaller that of the compression spring installation groove on the flange of the coupling.

其包括联轴器和压缩弹簧，联轴器可使洗衣机在洗涤模式和脱水模式间转换，其上形成有同步齿轮和连接齿轮，同步齿轮位于凸缘部上并在与联轴器限制件的齿轮相啮合时能使洗衣机进行洗涤；连接齿轮位于凸缘部下侧的外圆周面上并在与外连接器上的齿轮相啮合时能使洗衣机进行脱水；压缩弹簧安装在联轴器的上端并作用于联轴器，使其始终向下移动，其特征在于：所述的压缩弹簧的终端部直径较联轴器凸缘部上的压缩弹簧安装槽直径小。

From 2004 to 2007, 34 cases were treated with extrapedicular screw fixation in Department of Orthopaedics, Third Affiliated Hospital of Sun Yat-sen University. The screw entry point, angle, depth and diameter were measured and defined on the thoracic vertebrae pedicle by CT thin-slice scan in standard prone for all cases before operation. 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.

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。

Results Anatomic measurements showed vadian canal was located behind the sphenoid-palatine hole, and its external orifice was shaped as infundibular. The vertical dianseter was (3.5±0.9) torn and the horizontal diameter was (2.9±0.5) mm.
