尖角

Function relations between the twist drill design and the grinding parameters are derived.

并以尾隙角为补充参数，惟一地确定钻尖的刃磨参数。

The forming of flank of conical twist drill was studied and mathematical model of twist drill tine was founded in order to get formula of back clearance.

研究了锥面麻花钻后刀面的成型，建立了钻尖的数学模型，由此确定了后角的计算公式。

He struck at the projecting part of his helmet and drove the spear into his brow; the point of bronze pierced the bone, and darkness veiled his eyes; headlong as a tower he fell amid the press of the fight, and as he dropped King Elephenor, son of Chalcodon and captain of the proud Abantes began dragging him out of reach of the darts that were falling around him, in haste to strip him of his armour.

他首先投枪，击中插顶马鬃的头盔，坚挺的突角，铜尖扎进厄开波洛斯的前额，深咬进去，捣碎头骨，浓黑的迷雾蒙住了他的眼睛。他栽倒在地，死于激战之中，像一堵翻塌的墙基。他猝然倒地，强有力的厄勒菲诺耳，卡尔科冬之子，心胸豪壮的阿邦忒斯人的首领，抓起他的双脚，把他从枪林矛雨中拖拉出来，试图以最快的速度

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。

Plants reddish hirsute; branchlets angular; inflorescences glomerate or paniculate, rarely to 4 cm; leaf blade apex cuspidate, margin serrate or dentate, teeth callose

植株带红色的具粗毛；小枝具角花序团集的或圆锥状，很少对4厘米；叶片先端骤尖，边缘有锯齿或具牙齿，齿callose 9 Maesa permollis 毛杜茎山

Male flowers: stamens free or ± connate into a tube; anthers 2-celled, extrorsely dehiscent by longitudinal slit; connective apical appendage hornlike or apiculate, sometimes unappendaged.

雄花：雄蕊离生或合生成管；花药2室，向外纵向开裂；药隔顶端附属物角状或者具细尖，有时无附属物。

Stems angular, glabrous. Radical leaves: stipules brown, membranous, abaxially glabrous; petiole glabrous; leaf blade with 7–9 pairs of leaflets; leaflets petiolulate, green on both surfaces, fasciated or fasciated lanceolate, 5–7 × 1.5–1.7 cm, both surfaces glabrous, base subcordate to obliquely truncate or rounded, margin acutely incised serrate, apex rounded to acute; cauline leaves: stipules green, falcate, herbaceous, margin incised serrate; leaf blade resembling that of radical leaves but leaflets fewer and narrower higher up stem.

茎具角，无毛；胚根叶：托叶使成褐色，膜，背面无毛；叶柄无毛；叶片具7-9对小叶；具小叶柄的小叶，绿色在两面，扁化或者扁化， 5-7 * 1.5-1.7 厘米，两面无毛，基部近心形在斜截形或圆形，边缘尖锐锐裂状锯齿，先端圆形的到锐尖；茎生叶托叶绿色，镰刀形，草本，给锐裂状锯齿镶边；叶片象胚根叶的那但是高的更少和狭窄的小叶向上茎。

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.

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
