1The axial evolution law on the structure and the aerodynamic characteristics of the asymmetric flows around slender bodies of revolution at incidences is summarized:whether the flow asymmetry is powerless or powerful,the flow always appears in the structure that lee-side vortices rise,and shed vortices form,and new lee-side vortices come into being alternately on opposite sides of a slender body of revolution axially from nose apex downstream to afterbody,and always induces the sectional side force of waving quasi-sinusoidally downstream axially.

1总结出细长旋成体有攻角非对称绕流流场结构和气动力特性的轴向演化规律：无论非对称性强弱，沿轴向从头部尖顶往后体，非对称绕流总是呈现为左、右两侧背涡交替从物面向上飘起、形成脱落涡、再衍生出新生背涡的流场结构，并诱导出沿轴向呈类似正弦曲线形式振荡分布的截面侧向力。

Results: Fifty-two of 66 patients with unilateral fractures were, after 9–13 years, rated as excellent/good according to the Green and O'Brien score as modified by Cooney et al.

结果：66例单侧桡骨无故骨折患者，有52例在伤后9－13年GOBC评分为优良，AO骨折分类与结果无关，相当多的患者仍遗留骨折移位：背侧成角（小于60岁者，平均13°，大于60岁者，平均18°），与伤时相比桡骨存在短缩（小于60岁者，平均2mm，大于60岁者，平均3mm），5例患者复位后仍存关节面缺损（1－2mm），但是仅有1例患者后来发展成了轻度的骨性关节炎。

Results:The TFCC was supplied by the dorsal and palmar branches of the anterior interosseous artery.

结果：三角纤维软骨复合体的血供主要来自骨间前动脉的掌侧支和背侧支。

On the basis,design retrograde radial bone island flap pedicled with anterior interosseous artery.

临床设计以骨间前动脉背侧支为蒂的桡骨皮瓣逆行移位，骨皮瓣中桡骨瓣支撑于第一、二掌骨间或修复掌骨缺损，皮瓣修复虎口、手背尺桡侧的皮肤缺损。

Methods The structure of back and lateral chest area were dissected and the origin, alignment and distribution of the intercostals nerve within the area of latissimus dorsal muscular flap were observed in 40 adult cadaver specimens.

在20具40侧成人躯干标本上，采用大体解剖方法结合4倍显微镜，解剖后背区及侧胸区层次结构，观测分布于背阔肌区域的肋间神经的来源、走行及分布规律。

Because of the biceps and triceps' contract force and the reacting force of trochlea humeri, compressive stress was produced in the front of olecranon, while tensile stress in the back. The stress caused olecranon fracture. The place of most fracture lied between the tine and the middle, and most of fracture line was transverse or oblique.

由于肱二头肌、肱三头肌的收缩和肘关节反力的作用，尺骨鹰嘴关节侧产生压应力，背侧为张应力，导致尺骨鹰嘴发生骨折，骨折多发生在尖腰部，骨折线多呈横形或短斜形。

Results The number of synaptic terminals from primary afferent fibers in spinal lamina Ⅱ in morphine dependent group was significantly more than that in control group,among which the number of synaptic terminals from unmyelinated afferent fibers increased 61%.

结果发现，手术侧备用根初级传入纤维在脊髓后角Ⅱ板层内的侧支出芽和突触重建明显加快，起到代偿因切除大部分背根造成靶神经元在结构上和功能上去神经支配的作用［2］。

Fruit ellipsoid, dorsally compressed, glabrous; ribs filiform, dorsal and intermediate ribs close together, lateral ribs remote; vittae 1 in each furrow, 2 on commissure, very small.

果椭圆形，背压扁，无毛；丝状的棱，相近的背棱和中间棱，侧棱稀疏；油管每棱槽1，在合生面上2，很小。

RESULTS: The fibers of optic nerve projected to the dorsomedial side of suprachiasmatic nucleus and the fibers of hypoglossal nerve projected on the hypoglossal nucleus on dorsomedial portion of the medulla oblongate.

结果：视神经纤维投射到视交叉上核背内侧；舌下神经纤维投射到延髓背侧的舌下神经核区，结果显示神经元的胞体和轴突结构清晰。

The authors sug-gest that the decreased density of BDNF positive products in lamina II on the 3rd and 6th day was related with the degenerationof the nerve fibers and varicosities after section of the adjacent dorsal roots. On the 12th day, the remaining L6 dorsal roots un-derwent collateral sprouting compensatoryly and reestablished functional connection with target neurons.

作者认为3 d、6 d的减少主要与邻近背根节切除后，其神经纤维和膨体溃变有关；12 d时，保留的Ls背根逐渐侧支出芽，且与靶细胞再建功能联系，故脑源性神经营养因子阳性神经纤维和膨体数均趋于恢复。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
