It allows for maximum strength-to-weightratio and the efficient transferring of forces in order to minimise stresses and avoid whole structure failure.
这种多孔性材料可以使强重比最大化，有效转移承受力，使压力最小化，避免整个结构的垮掉。

Forgings yield parts that have high strengthtoweightratio, thus are often used in the design of aircraft frame members.
锻造生产的零件具有较高的强度重量比，所以常被用在飞机结构零件的设计中。

Nowadays, large safety coefficients have been adopted for strength and rigidity of the mililary communication vehicle, and the ratio of carriage weightto communication equipment loading is about 1.
