Construction is a combination of workmanship and choice of materials. Take this computer, if I pull the silicon out, I replace it with gallium arsenide, leave everything else the same.
构造则是技巧和材料的选择,的结合,拿这个电脑为例,如果我将硅取出,替换成砷化镓,其他东西不变。
So, that's the power of the choice of materials, and why? Properties.
所以,这就是选择物质的力量,为什么呢,因为属性。
