角样的

A method of construct a quadratic uniform B-spline curve through data points is given.If the relative curvature of a certain curve on the first control point and the direction angle of the first port's tangent vector is given,here can get the whole curve by using the character of the port of quadratic uniform B-spline curve.

提出了一种二次均匀B样条插值曲线的构造方法，首先给定某一段曲线首点的相对曲率和该段曲线的首端切矢量的方向角，利用二次均匀B样条曲线的端点性质，求出其余各段曲线控制顶点，来生成整条插值曲线。

I found besides these Chests, a little Cask full of Liquor, of about twenty Gallons, which I got into my Boat, with much Difficulty; there were several Muskets in a Cabin, and a great Powder-horn, with about 4 Pounds of Powder in it; as for the Muskets, I had no occasion for them; so I left them, but took the Powder-horn: I took a Fire Shovel and Tongs, which I wanted extremely; as also two little Brass Kettles, a Copper Pot to make Chocolate, and a Gridiron; with this Cargo, and the Dog, I came away, the Tide beginning to make home again; and the same Evening, about an Hour within Night, I reach'd the Island again, weary and fatigu'd to the last Degree.

我费了九牛二虎之力，才把酒桶搬到小船上。船舱里还有几支短枪和一只盛火药的大角筒，里面大约有四磅火药。短枪对我来说已毫无用处。因此我就留下了，只取了盛火药的角筒。另外我又拿了一把火炉铲和一把火钳，这两样正是我十分需要的东西。我还拿了两把小铜壶，一只煮巧克力的铜锅和一把烤东西用的铁钯。我把这些货物通通装进我的小船，再带上那只狗，就准备回家了。这时正值涨潮，潮水开始向岛上流。天黑后不到一小时，我就回到了岸上，但人已劳累得疲倦不堪了。

The similar drawing of the hyperbolic line is argument according to my experience with teaching, which is on the head surfaces of hex nut and used in the engineering drawings, through building three-dimensional model in AutoCAD.

本文通过在AutoCAD中建立三维虚拟对比模型，探讨了工程图样中六角螺母和六角螺栓头部外表面双曲线在计算机辅助设计中的近似画法问题。通过对比，论证了样条曲线替代圆弧近似双曲线改进画法在计算机绘图中的合理性和优越性。

Main HPV7(9/18) positive samples\' pathology manifestations matched the characteristics for HPV7 infection,which showed papillomatosis and acanthosis,deep-stained cells including keratohyalin granules in middle size,and obvious hyperkeratosis and parakertosis.

HPV7阳性(18份)的病理象特征：(1)乳头瘤样增生和棘层肥厚；(2)内含中等大小的透明角质颗粒的细胞深染；(3)显著的角化过度和角化不全。

The pattern in which lesions involute may be useful in diagnosis, the typical keratotic papule of pityriasis lichenoides varioliformis acuta for example.

退行后皮损的形态也有诊断价值，如急性痘疮样苔藓样糠疹的典型的角化性皮损。

And the polar angle and the polar radius was represented into AutoCAD polar coordinate, the involute was drawn through the spline linear tool. And then, a section of the involute was intercepted with the diameters of the point circle and the root circle, used it as the tooth face of the spline. The involute tooth thickness was drawn using the diameter of the divided circle and the tooth-form was drawn through rotating, mirroring image and cutting.

根据DIN 3960渐开线花键的坐标值，用EXCEL函数功能计算出不同压力角下渐开线的极角和极半径，表示成AutoCAD极坐标并通过样条线工具绘制出渐开线，再用齿顶圆和齿根圆直径截取一段渐开线作为为花键齿面，并用分度圆直径绘制出渐开线齿剖面，经镜像和裁剪便可绘制出渐开线齿形。

According to road designing data of mileage,coordinate,azimuth angle of tangent or straight line,curve radius,the length of spiral line from main point of curve or straight line starting point,we can calculate the coordinates of center line points and boundary line point s in any form of road under the same coordinate system.

根据线路设计资料提供的曲线主点里程、坐标、切线方位角、曲线半径、缓和曲线长度的已知数据，计算出任意线形的中桩、边桩在线路统一坐标系中的坐标，利用全站仪极坐标放样程序，以线路附近的控制点或加密点为测站，准确、快速放样各点。

Methods Twenty-two patients （12 male,10 female）histologically proved for epidermoid tumor of the cerebellopontine angle area were studied by using MR equipment.

目的 探讨磁共振弥散加权成像、液体抑制反转恢复序列在桥小脑角区表皮样囊肿诊断中的应用价值方法收集我院经手术病理证实的表皮样囊肿22例，男12例，女10例，行MR检查。

When compared with S7 and its putative protein of Lymantria dispar cypovirus 1 and Bombyx mori cypovirus 1, 97.2% and 87.0% identities in the nucleotide level, and 98.7% and 92.8% identities in the amino acid level were found, repectively. BLAST search program revealed some similarity between DpCPV-HN P50 and DnaK-like protein of Mycoplasma hominis.

该基因组与舞毒蛾质多角体病毒1型和家蚕质多角体病毒1型S7节段有很高的同源性，核苷酸序列同源性分别为97.2%和87.0%，氨基酸序列同源性分别为98.7%和92.8%。P50多肽与人型支原体的DnaK样蛋白在C-末端有相似性。
