这样的2维宇宙模型就像是球体，不可能出现平行的测地线(测地线是曲面上的直线)——两直线必然在某点相交。
A two-dimensional model of such a universe would look like a sphere. It's impossible to have parallel geodesics (straight lines on a curved surface) — the two lines will cross at some point.

Viewed in profile the top of the skull and the top of the muzzle lie in two parallel, straight lines of equal length, divided by a slight, but perceptible "stop" or break.

A new linear sensor consisting of two parallel carbon fibers, energized by the alternative current has been developed.
结合序列图像中目标特性，检测出边缘直线中特定的两条平行直线进而获得目标的中轴线方程。
According to the characters of the target in the image, the specified parallel line has been detected to get the equation of the axes.
随后，取圆柱体分布于两条相互平行的直线上，则问题演变为双排弹性桩屏障对于弹性波的隔离问题。
Then, all the cylinders are distributed in two parallel lines, which makes the problem turn into the vibration isolation using double row of elastic piles.
平行直线是在同一平面内的直线，向两个方向无限延长，在不论哪个方向它们都不相交。
Parallel straight lines are straight lines which, being in the same plane and being produced indefinitely in both directions, do not meet one another in either direction.
