三截

Describes follow-through and the three-point landing, both of which are essential components of the straight lead.

讲解截拳道先导前手直拳的要领。本期讲解的是发力瞬间的三点支撑与跟进动作要诀

It regards the cutting track of virtual surgical knife as the cutting intersection of a polygon prism and a triangular mesh model.

该算法用凸柱体模拟虚拟手术刀对三维网格模型进行切割，根据截骨术的切口类型构造柱体，用此柱体进行切割实现骨块的分离。

Draw three views of a cutting triangular pyramid.

求三棱锥被截切后的三视图。

Draw V, H views of a cutting triangular pyramid.

求正三棱锥被截切后的 V、H 投影。

Trihedral corner reflectors ; shooting and bouncing ray ; radar cross section

三面角反射器；射线跟踪法；雷达散射截面积

In this course three-dimensional finite element method is used to calculate the stress and deformation of the metal structure.The influence coefficient method is adopted to obtain the expression between the load and the offect ,and form the limit state equation of all failure mode.Finally.corresponding reliability indices are obtained with the JC method under truncated distribution.

在此过程中，运用三维有限元计算了门机金属结构的应力和变形，采用影响系数法，建立起荷载与荷载效应的显式关系，进而建立了各失效模式的极限状态方程，再用可截尾处理的JC法求出相应的可靠指标。

Methods:The whole mature protein coding sequence of three truncated dystrophin gene was amplified by RT-PCR method applied to human muscle cDNA. The fragment was inserted into prokaryotic expression vector pET28a plasmid.

以人肌肉组织cDNA为模板，采用RT-PCR扩增三个截短的肌营养不良蛋白cDNA，分别克隆入原核表达载体pET28a中，经限制性内切酶双酶切及DNA序列分析鉴定目的基因。

Then he knelt by the fire and painfully wrote something upon each of these with his "red keel"; one he rolled up and put in his jacket pocket, and the other he put in Joe's hat and removed it to a little distance from the owner. And he also put into the hat certain schoolboy treasures of almost inestimable value -- among them a lump of chalk, an India-rubber ball, three fishhooks, and one of that kind of marbles known as a sure 'nough crystal.

然后他就在火堆旁跪下，用他那块红砚石在树皮上吃力地写了几个字；他把一块卷起来，放到上衣口袋里，另一块放在乔的帽子里，他把帽子挪远了一点后又在里面放了些被小学生视为无价之宝的东西――一截粉笔；一个橡皮球；三个钓鱼钩和一块叫做&纯水晶球&的石头。

Animals were divided into control group and 5 experimental groups. Each experimental group had 2 canines and the central of masseters and geniohyoid were dissected out in 5th, 10th day in distraction and 2nd, 4th, 8th week after distraction.

牵张器采用口内下颌骨牵张器，截骨部位在第三乳前磨牙与第一恒磨牙间且垂直于下颌骨下缘，牵张方向为前后向。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
