一种用于易碎材料(1)中的自攻螺钉(10)，包括：主体(12)，其具有中心轴(13)、带有凸缘的后端部(14)、用于钻孔的前端部(16)和位于所述后端部和前端部之间的通常为圆柱状的部分(18)，所述圆柱状部分(18)的外表面(20)上布置有螺纹(22)，其中主体从距离带有凸缘的后端部的预定的距离处开始分叉为第一腿(24)和第二腿(26)，第一腿向前伸入钻孔尖端(28)，并且具有相对于中心轴向外成钝角的通常面向后的肩部(30)，主体(12)具有容纳细长状紧固件(2)的轴向孔(32)，轴向孔(32)基本延伸穿过带有凸缘的端部(14)和通常为圆柱状的部分(18)，并且通向通常面向后的肩部(30)，螺钉(10)具有钻孔状态和固定状态，在钻孔状态，第二腿(26)套在第一腿(24)的通常面向后的肩部(30)之后，并且在固定状态，腿彼此转动分离。

The in vitro cell cultivated system was improved to form positive and backward flow fields in the loop so as to simulate bidirection blood flow or vortex flow at vessel embranchment, bifurcate, straitness or sinuosity.

对内皮细胞体外培养装置加以改进，在回路中形成既能正向流动，又能逆向流动的流场，旨模拟在血管分支、分叉、狭窄或弯曲处产生的双向血流或涡流。

Result:In most cases, the recurrent laryngeal nerve diverges at the level of 1.0～2.5 cm under the cricothyroid articulation for forming the extralaryngeal division.

结果：95%喉返神经在距同侧环甲关节下方1.0～2.5 cm处形成喉返神经喉外分叉点，根据分支情况可将其分为三型。

The sigmoid mesocolon is a peritoneal fold attaching the sigmoid colon to the pelvic wall. The apex is divided near the left common iliac artery and serves as a potential site for an internal hernia.

乙状结肠系膜是固定乙状结肠到骨盆壁的腹膜皱襞，其尖端在接近左侧髂总动脉处分叉，成为潜在的腹内疝的部位。

The calculated results indicate that a bifurcated A. wave can be formed when the shock passes through the flame, and pre-induced shock transmission in the flame leads to the formation of Mach stem, followed by spheral shock wave. The Rayleigh-Taylor and Kelvin-Helmholtz instabilities occurred in the flame induced by shock wave lead to the flame distortion and breakup.

计算结果表明，激波掠过火团时，分叉形成λ波；前引激波在火团内透射并在轴线处碰撞形成Mach杆，进而逐渐发展为球形激波；火焰在激波作用下先后出现Richtmyer-Meshkov不稳定和Helmholtz不稳定，火焰逐渐变形以致破碎；燃烧速率因此剧增。

Bifurcation or anastomoses of capillaries approximately took place at right angles in a T-shaped pattern and capillaries showed a lot of ring-like compressions.

毛细血管的分叉或吻合大都发生在&T&样的直角处和毛细血管显示有很多环形压缩。

Methods To observe the common carotid artery and its bifurcation, the internal carotid artery, external carotid artery intima-media thickness, plaque echo and hemodynamic changes.

方法观察颈总动脉及其分叉处、颈内动脉、颈外动脉内中膜厚度、斑块回声及血流动力学改变。

Results:(1) The two nerves were found anatomically related at 5～10 mm and 26～30 mm respectively following hypoglossal nerve entering the muscle.(2)The diameter of the two nerves were observed to match well with each other or with the main branches at 10 mm following the branching of hypoglossal nerve.(3) At 6～10 mm prior to the branching of hypoglossal nerve there was a branch going to the lingual muscles and plexiform of lingual nerve.

结果：(1)舌下神经与舌神经之间有二个恒定的联系部位，即舌下神经分支进入舌肌后最初5～10 mm处和26～30mm处；(2)舌下神经与舌神经最佳吻接部位，我们认为应在舌下神经主干分叉后10 mm左右；神经直径测量也发现神经直径与舌神经主干和分支直径较为匹配，且此区有利解剖，便于神经吻合；(3)舌下神经分叉之前，在神经干上方距分叉约6～10 mm处有一较固定分支，参与分布舌肌并与舌神经呈丛状结构。

Methods 42 cases mature neonate with MSCT scanning in lung were collected and randomly divided into three groups averagely. The tube current was 50 mAs and 30 mAs for low dose scanning and 200 mAs for routine dose. The CT value of region of interesting and standard deviation were measured in the aorta that region of carina of trachea. And compared the noise, image quality, CT dose index and dose length product between two low-dose scannings and routine dose.
