The orthogoi al multilayer sandwich plate which provides considerable strength, stiffness and stability has been used in some important engineering structures, such as the composite material bridge.

正交各向异性多层夹芯层板具有较好的强度、刚度和稳定综合性能，已在一些重要承力结构（如复合材料桥）中应用。

The material for building the bridge must be very strong so that it may not break in use.

为使桥梁不致在使用中断裂，建造桥梁的材料强度必须非常高。

This standard of judgment also appears in The Brown Decades (1931) when he deals with the Modernist architecture and the Brooklyn Bridge where aesthetics and material come together.

这种评价标准，他同样在《棕色的年代》里用来评价现代建筑和布鲁克林大桥，他认为那才是审美和物质走到了一起。

youdao

So you pick a better material like iron and steel, that makes a better bridge, we know that now because we have experience with bridges, but still your bridge might fail.

你选择了钢铁作为材料,来造了一座更好的桥,我们现在能够明晰这一点,是因为在造桥这件事上我们现在很有经验,但即使是我们现在造的桥也仍然会倒塌

For example, one thing that could happen is that you build it up with wood and clay, you pick the wrong material for a bridge, and it will not stand up to the forces of nature.

例如,其中的一个问题是,选择了木头和粘土作为造桥的材料,你就选错了材料,这座桥难以与自然力相抗衡

So you build it with a material like silver and gold, and then you encounter the problems of society that your bridge might get stolen because somebody thinks they have a better use for silver and gold than your bridge.

但如果你用金或银这样的材料,你又会面对新的问题,你的桥会被偷走,因为有人认为金和银有比造桥更好的用途
