您要查找的是不是：
- If the norm is 1, you have a so-called unit quaternion (just as you would have a unit vector). 假如平均值为1，你就得到所谓的单位四元数（正象单位矢量）。
- Draw these segments; then, for each segment, draw the same set of line segments transformed to use that segment as the unit vector. 绘制这些区段之后,绘制同一套变形线条,用这个区段作为单位向量。
- For drill point with planar flanks, using toolroom microscope, we measure the angles relevant to unit vector on the flanks and transform these data into design parameters. 我们利用工具显微镜,对平面型后刀面枪钻测量有关的角度,确定后刀面法矢方向,并将数据转换为设计参数。
- Tank Regulator Design Using Unit Vector Control 坦克稳定器单位向量变结构设计
- Unit vector in the meridional direction 经向单位矢量
- Unit vector in the zonal direction 纬向单位矢量
- Unit vectors are used to represent the directions of cutting edges and tool surfaces so that the calculating process and formulats are simplified. 在求解过程中,用单位矢量来代表刀刃线和刀面的外法线方向,简化了推导过程和计算公式。
- In calculation of inner flew field within turbomachinery, partial differentials of three unit vectors in a curvilinear orthogonal coordinates must be employed. 在叶片式流体机械的内流场计算中,要使用曲线坐标系的三个正交单位矢量关于曲线坐标的偏导数。
- A kinematics model by post D-H method for 4R-robot was offered in this paper, which derived the manipulator finger position and its attitude with unit vectors of direction cosine. 采用D-H后置法建立了4R机器人运动方程,建立机器人执行机构在空间相对位置关系的数学模型,由此可解出手部位置和用单位矢量方向余弦表示的姿态。
- The luminous intensity on unit area. 单位面积上的发光强度。
- The family is the smallest social unit. 家庭是社会最小的单位。
- Pressure is force per unit area. 压力就是电单位面积上的力。
- A set of data elements which are handled as a unit. 作为一个单元来处理的一组数据元素。
- The family is the basic unit of society. 家庭是社会的基本单位。
- A metric unit of area equal to 10 ares. 十公亩面积的公制单位之一，等于十公亩。
- A metric unit of mass equal to 100 grams. 百克公制质量单位，等于100克。
- A unit of power equal to 1,000 watts. 千瓦功率的单位，等于1,000瓦。
- A unit of frequency equal to one cycle per second. 赫兹频率的单位，等于每秒一周
- A unit of currency in Chile, Panama, and Uruguay. 分智利、巴拿马和乌拉圭的货币单位
- A metrical unit consisting of seven feet. 七韵步由七个音步组成的格律单位
