节锥

2At drive than will certainly,driven gear, while having the more same sizes, hyperboloid have diameter not larger of gear wheel not initiative than corresponding spiral awl gear wheel, intensity and bigger initiative gear wheel axle and bearing rigidity of higher teeth of a cogwheel.

螺旋角是指在锥齿轮节锥表面展开图上的齿线任意一点A的切线TT与该点和节锥顶点连线之间的夹角。在齿面宽中点处的螺旋角称为中点螺旋角(图5—4)。通常不特殊说明，则螺旋角系指中点螺旋角。双曲面齿轮传动比为

Generally, this new technique has three steps. First, mill the necked-in casing with the efficient milling cutter head; and then salvage and back-off the buried pipe by a suitable fishing tool based on fish tip status; at last, orderly use a efficient taper pups and taper to extend and dredge the casing refitment section.

该技术首先利用高效高效铣削式套铣头对缩径套管进行套铣，然后根据鱼顶情况选择合适的打捞工具打捞、倒扣出被埋管柱，最后将高效铣锥短节和铣锥对修套井段进行扩铣通径。

Objectie To inestigated the seurity and alidity of computed tomographic-guided sterotactic aspiration, and explore the risk factors for prognosis in patients with ganglionic intracerebral hemorrhage treated by stereotaxic aspiration.

目的：了解CT指导下基底节区脑出血锥颅抽吸治疗的有效性与安全性，并对影响锥颅治疗脑出血患者预后的一些相关因素进行分析。

Methods The medical records and CT scans of 113 inpatients with ganglionic intracerebral hemorrhage treated by stereotaxic aspiration and 91 inpatients without stereotaxic aspiration treatment were retrospectiely reiewed.

回顾性分析2000年12月1 日到2002年6月1 日间我院病案首页数据库中所有行CT指导下行锥颅抽吸治疗的基底节出血病例以及同期符合锥颅抽吸治疗手术指征而行内科保守治疗的基底节出血患者。在患者出血后30天进行疗效评定。

Based on the equations, a new method for the geometrical design of hypoid gears is presented.

在这组方程的基础上，提出了一种几何设计的新方法，以大轮的节锥角和节圆半径以及小轮的螺旋角这三个参数为自由变量，以准双曲面齿轮副的偏置角为中间变量，用数值求解方法能够非常方便可靠地确定节锥的参数。

Solves this symptom method to divide into the surgery and the non-surgery treats, the non-surgery treats for example the physical property treatment and the pharmacological treatment, the effect is not often good, the surgery treats may divide into the traditional surgery and micro creates the surgery two kinds, the traditional surgery method is in the lumbar vertebra fusion the pexia, although this method excised has created the lumbar vertebra narrow yellow ligament and the small surface joint, but the surgery time was long, the wound was big as well as although the lumbar vertebra fusion and fixed has removed the pathological change stage abnormal movement, but the neighbor stage's abnormal movement increased, between the awl in plate's pressure elevated obviously, the small articular process exceptionally drew back changes with the fixed stage bone quantityThe loss, causes the fixed stage vertical motion stage to draw back changes ASD[1], but new micro creates the surgery is opens a small wound in the back, and implants the interspinal to open, then solution lumbar vertebra narrow sickness question.

解决此种症状的方法分为手术及非手术治疗，非手术治疗例如物理性治疗和药物治疗，往往效果不佳，手术治疗又可分为传统手术和微创手术二种，传统手术方法就是腰椎融合内固定术，虽然此种方法切除了造成腰椎狭窄的黄韧带和小面关节，但手术时间长，伤口大以及腰椎的融合和固定虽去除了病变节段的异常活动，但邻近节段的异常活动增加，锥间盘内的压力明显升高，小关节突的异常退变和固定节段的骨量丢失，导致固定节段上下运动节段的退变ASD[1]，而新型的微创手术是在背部开一个小伤口，并植入棘突间撑开器，进而解决腰椎狭窄症的问题。

The results show that a large number of cone cells distributes in the central area of retina, and the number of cell in outer nuclear layer and ganglion cell layer is approximate, and the protuberances of pigment epithelium cells extend to cones and rods layer, which suggest that Zoacys dhumnades is diurnal habitual species.

结果表明，乌梢蛇视网膜中央区分布着大量的视锥细胞，外核层与节细胞层的细胞数量相当，色素上皮层的细胞有许多突起伸向视杆视锥层内，说明乌梢蛇是一种昼行性蛇类。

A set of fundamental equations that consist of four formulae and contain seven pitch parameters is established through the pitch cone geometrical relationship of a pair of hypoid gears.

通过准双曲面齿轮副的节锥几何关系，建立了包含7个节锥参数并由4个方程构成的节锥参数基本方程组。

Hypoid gear ; pitch cone ; pitch parameter ; geometrical design

准双曲面齿轮；节锥；节锥参数；几何设计

In Chapter 2, we study the existence of positive solutions for two-point and three-point boundary value problems of nonlinear differential equations.

第一节，运用锥拉伸与锥压缩不动点定理研究二阶三点边值问题正解的存在性。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
