It allows for maximum strength-to-weight ratio 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 strength to weight ratio, 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 weight to communication equipment loading is about 1.

目前装备的通信车厢体强度和刚性均采用较大安全系数设计，其重量与装载设备总重量的比值一般在1。

That might not seem like much, but considering most rigid robot arms can only lift a fraction of their own weight, it represents a sizable gain in strength-to-weight ratio.
