It transformed the mechanic problem from the continuous skew beam bridge into the continuous straight beam bridge.

它把一个连续斜梁桥的力学问题转化为连续正梁桥的力学问题。

It is usually expressed by the decibels which is the straight beam probe tested the second time subtracting from the first bottom surface echo amplitude.

通常用纵波直探头测试的第几次与第一次底面回波幅度所差的分贝数表示。

When vertical loads applied to a straight beam, the structure will have large bending and torsion and lose steady, this phenomenon is called lateral torsion buckling.

结构失稳的类型有很多种，其中直梁在竖向荷载的作用下，结构发生了较大的竖向弯曲变形和侧向扭转变形，而导致结构失稳称为梁的侧扭屈曲。

Walking straight on a narrow beam is frustrating and wrong.

That means the beam produced is of higher quality than other lasers, is extremely straight (even by the exacting standards of a normal laser beam) and can thus be focused onto a small area.

ECONOMIST: Solar power from space

This exploits one of the predictions of Einstein's general theory of relativity: that the path of a beam of light (which is a straight line in empty space) is bent inwards by the gravity of a massive object.
