直角

By sleeping at right angles to the line therefore you are minimising your exposure to its lines of force.

由睡成直角线因此你尽量减少你暴露其行生效。

Also the biggest pressure loss is caused by rectangular winglets and the less is that of delta winglets and trapeze winglets with a bevel angle φ=0°.

矩形翼压力损失最大，直角三角翼和φ=0°梯形翼流阻较小。

Experiments were done to contrast the heat tansfer enhancement and pressure loss caused by several single-pare vortex generators such as delta winglets,rectangular winglets,trapeze winglets,bevel-cut half-cylinder VG and bevel-cut half-elliptical column VG,which were installed in a rectangular tunnel respectively.

在雷诺数为4000～38000的紊流范围内对矩形风道内分别布置单排一对直角三角翼、矩形翼、梯形翼、斜截半圆柱体、斜截半椭圆柱体等涡流发生器的强化传热效果和压降特性进行了对比实验。

For internal waves this is easily shown from (2) to be at right angles to the wavenumber vector k. In other words, energy propagates parallel to the wave crests, rather than at right angles as for surface waves!

这是内波容易证明的（2）在右边角波数矢量光换句话说，能源传播平行的波峰，而不是在作为面波成直角！

This paper presents the separate resolution of free rigid body motion into tree wrench motion s.

文中将自由刚体运动分解为三个直角坐标轴上的力螺旋运动，同时也给出了自由刚体运动在这种力螺旋运动的分解下其速度和加速度的表达

The two vanes are at right Angles in plan, and each is either all shaded or all in sunlight

上、下两块觇板在一平面图上相交成直角，每块觇板全是阴暗的，或全被阳光照射。

Gillette's own walking paths were constructed with near-vertical steps, stone-arch bridges, and wooded trestles spanning up to forty feet.

在吉列散步的小径上，有修成几乎是直角的台阶，有拱型石桥，还有一个跨度接近20英尺的木质栈桥。

A parallelogram with adjacent sides of unequal lengths; an oblique-angled parallelogram with only the opposite sides equal.

相邻的边长度不相等的平行四边形；只有相对的边长度相等的非直角平行四边形。

Two coordinate conversion matrices respectively for rotation angles in two rotators express the same conversion,they are thus equal,and by contrasting them the relationship between these two kinds of rotation...

分别用两个三自由度转动体的转角所表示的两个直角坐标系之间的空间旋转坐标变换矩阵，代表同一变换，因而相等，由两个矩阵的对应元素相等可直接得出两个转动体之间的转角关系式。

The digital part includes rectangular-to-polar converter and digital phase modulator.

数位部份包括直角座标至极座标转换器及数位相位调变器。
