断

The rigid fixation is statically preloaded and as the bone is loaded, there is not motion of fragments. The flexible Fixation systems can not be statically preloaded. As the-bone is loaded, both compression and distraction occur at the fracture site. Because micromotion at the fracture ends occurs within the limits that the callus will allow.

刚性固定在动载荷下断端没有活动而有静态预载荷；非刚性固定没有预静载荷，在动载荷下断端压缩和分离交替出现，由于动载荷下断端存在相对活动，所以骨折在外骨痂不断形成过程中达到愈合。

Standing by jejunum to break upright point, seaming stitch to fastening velar predestined relationship, the needlework that be the same as a root is in be apart from jejunum to break upright 6cm place to seam stitch; is velar predestined relationship seams stitch next, the needlework that be the same as a root is in be apart from jejunum to break upright 6cm place to seam stitch, loose loose ligate two silk thread, make jejunum retroflexions 3cm, the mucous membrane that retroflexion the face uses electric bright or carbolic acid tries to destroy, make its are lost secrete a function.

在靠近空肠断端处，在对系膜缘缝一针，同根针线在距空肠断端6cm处缝一针；然后在系膜缘缝一针，同根针线在距空肠断端6cm处缝一针，松松结扎两根丝线，使空肠翻转3cm，将翻转的黏膜面用电灼或石炭酸加以破坏，使其丧失分泌功能。

In this paper, new approaches were attempted to improve the accuracy in the measurements of both tree ring width and the sectional area of bark.

利用校正系数对传统方法测定的结果进行校正，或者在直径测定时采用符合实际直径的方位；对于有裂隙的树皮（假设内皮厚度为0）的断面积，把目前的去皮半径当作带皮半径进行计算，而不是带皮断面积和去皮断面积之差。

The geotectonic evolution in east Tarim b asin has involved seven stages:basement formation in the pre-Sinian,faulted blocking of continental margin in pre-Caledoni an epoch,sag stage in late-Caledoni an epoch,foreland upwarp from Hercyni an to Indo-Chinese epoch,foreland b asin from Indo-Chinese to pre-Ye nshan epoch,intracontinental sag b asin in late-Yenshan epoch and faulted b asin in Himalayan epoch.

塔东地区的大地构造演化经历了前震旦纪基底形成阶段、早加里东期大陆边缘断陷盆地阶段、晚加里东期隆后坳陷阶段、海西期前陆隆起阶段、印支期—早燕山期冲断前陆盆地阶段、晚燕山期陆内坳陷盆地阶段和喜山期断陷盆地阶段

It is found that thrusting deformation in the accretionary prism is accommodated not only by deformation within largescale thrusting zones, but also by deformation along secondary thrusts and potentially more importantly along corescale structures such as microfaults and deformation bands.

发现逆冲变形不是只在大尺度的逆冲断层面上进行，而是弥散分布在主逆冲断层面、次级逆冲断层面以及断层面之间的更小的尺度上。

In the sonograms of Psittacula Agapornis after the section of right side NXIIts the ascending parts of the tone disappeared. This causes their vocalizations became the descendent-call.

牡丹鹦鹉在断右侧NXlltS后其声图中音调上升支消失，因而其叫声变为以降音调为主的降调叫声；在断左侧NXlltS后的声图中，其基本音以上的谐波成分减弱或消失而在断双侧神经后其声图表现为一系列具有较低基频的宽带谐波谱。

Results When the foot was in a relaxing position, the optimal position to observe anterior talofibular ligament with MRI was transverse orientation, to calcaneofibular ligament was transverse oblique, to posterior talofibular ligament and cervical ligament was coronal and to interosseous talocalcaneal ligament was sagittal orientation. The identifying signs of the ligaments were described.

结果 当足呈自然放松位时，距腓前韧带在横断位，跟腓韧带在斜横断位，距腓后韧带在冠状位，颈韧带在冠状位，距跟骨间韧带在矢状位断面上，为最佳观测方位，并提出了各韧带在断面上的辨认标志。

The present paper analyzes causes to the breakdown of the wire rod such as the central shrinkage cavity and carbon segregation, surface transverse cracks, harmful structure of bulky pearlite and web shaped carbonide and puts forward a few relevant measures for improvement in the physical product quality and reduction of fracture rate of the wire rod including proper control of the casting temperature,drawing speed, intensity of secondary cooling as well as adjustment of the intensity of control rolling and accelerated cooling and optimization of the drawing parameters.

通过对中心缩孔和碳偏析、表面横裂纹、粗大珠光体或网状碳化物不良组织等引起断丝原因的分析，提出通过合理控制浇注温度、拉速、二冷强度、控轧控冷强度及拉拔工艺参数等措施，改进盘条实物质量，降低断丝率。关键词 SWRH82B/SAE1080；脆断；质量分析；工艺控制
