The expression of optic axial Angle and ray axial Angle on light wave plane can be obtained by using the curve equations of the wavefront of light wave and normal plane of light wave.

利用光波面和光波法线面的曲线方程，得出了光波面上光轴角和光线轴角的表达式。

Radiographic examination included Cobb Angle, rotation Angle of apical vertebrae, and translation of the C7 vertebra from the center sacral line on the coronal plane.

This paper provides a new construction method used when the horizontal projection of the plane Angle is equal to its space Angle.

And just to give you a sense, if you do a cross-cut of this, you cannot show it from this angle, but it should really be sort of a dumbbell shape with the nodal plane in between the two nuclei.

告诉你们这些就是给你们点概念，假如你们把他横切切开，不能从角度上展示，但它还是会保留几分哑铃的形态,以及在两核之间的节面。

Another way to represent a point in a plane is I've got a radius and I've got an angle from the x-axis, right, and that's a standard thing you might do.

平面上面的点的方法,也就是极坐标,上面那种方法其实是，如果你们喜欢我这么说的话,笛卡尔坐标表示法。

It also helped seeing my videographer, Anthony Nielsen in a 2nd plane rolling upside down over the top of us to get a better angle filming our plane.

It helps to control the angle of the plane's nose during flight.

When Jeffrey Skiles, the co-pilot of the plane that made an emergency landing in the Hudson River in January 2009, explained how he and his captain decided that an airport landing was impossible, he described the same "gaze heuristic": The angle of the plane's descending glide made the airport appear to rise in their windscreen view clearly signaling that a landing there was doomed.
