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.

(甚至符合正常激光束的严格标准)这样就能将能量集中传送到一个小的区域范围内。

Students will determine the relative stiffness of two aluminum beam test specimens of equal cross sectional area but different cross-sectional shape and see how they conform to theory.

学生要确定两个横截面面积相同而形状不同的铝梁实验样本的相对刚度，并研究结果如何与理论一致。
