true vertical

The scheme is a transition between the box girder with vertical piers and the true arch.

该结构是具有垂直墩的箱梁桥钢与真正的拱桥之间的一种过渡形式.

While 2D PSD photo potential gradually decreases from the incident position of light to four electrodes and impacts on each other in two vertical directions. For given parameters, the error between the detected position and true incident position is up to 60%.

而二维PSD的光生电势分布以光源照射位置为中心向四个电极递减，垂直方向互相影响，在给定参数下光的入射位置与真实值相比有60%的误差。

caster is measured in the number of degrees that it is forward or backward from true vertical and is adjustable on many vehicles.

连铸是衡量的人数度，这是向前或向后从真正的垂直和是可调的许多车辆。
