Unlike the axe, the blade of the adze is set at right angles to the handle, so that, in use, the cutting edge is horizontal rather than vertical.

不同的是斧头，锛子叶片的设置成直角的处理，因此在使用中的，最前沿的水平，而不是垂直的。

The simulation shows that STFMPC signal is sensitive to Doppler frequency-shift,and its ambiguity function has one aiguille at the origin and four symmetrical right-angle set-squares with the aiguille as their common spindle.

通过计算机仿真，结果表明该信号是多普勒敏感信号，其模糊函数为在原点的1个尖峰和4个以尖峰为公共轴的有一定厚度的对称直角三角板。

The team also noted a hinged flap near the base of the wing, called an Alula, which is deployed at right angles to the wing, which may be being used as a air flow-control device.

这个小组还注意到，翼根附近铰接的副翼，被称为小翼的，对翼成直角配置，它可能被用来作为空气流量控制装置。

Function of an angle expressed as a ratio of the sides of right-angled triangle containing the angle .

直角三角形各角的函数是用各边的比来表示的。

A method of right angle auxilliary projection on an arbitrary plane is provided, by which the dihedral angle can be obtained directly.

提供一种在一般位置平面上的直角辅助投射方法，直接求两面角，具有概念明确唯一，作图方法简单，可以适应钣金划线工作中制造卡角样板的实际需要。

The common method for obtaining the angle of the plane figure to projection plane is through the right-angled triangle method after getting the double-face projection of the plane figure on the basis of the conception of maximum oblique line.

求平面图形对投影面的倾角，通常需要知道平面图形的两面投影，利用最大斜度线的概念，通过直角三角形法求得。

The positions of cam and dial were analyzed accompanied with their angular position, angular velocity and angular acceleration.

分析了凸轮和转盘的位置、角速度、角加速度的变化规律，给出了直角式精密分度凸轮的设计算法，同时计算了数控加工的刀位轨迹，并给出了四坐标联动数控加工和编程方法。

This invention has been possible since the problem of connecting the corner cube piece with the solid interior has been solved, so that the said corner piece can be self-contained and rotate around any semi - axis of the three-dimensional rectangular Cartesian coordinate system, be protected during rotation by the six caps of the solid, which is the central pieces of each face, to secure that the cube is not dismantled.

自从通过可靠的内部连接魔方角块的问题解决后，高阶魔方的出现成了可能。角块能够完全独立，并在三维直角坐标系的各个轴上旋转。而且在角块转动过程中，有6个可靠的cap提供保护。这种cap就是每个面的中心部分，它们可以保证魔方在转动的过程中不会散架。
