制作这种纳米级的金属线需要将一种有机分子和镓盐的混合物置于一个超级干净的银薄片上。

Production of such nanoscale wires need to be a kind of organic molecules and gallium salt mixture placed in a super-clean silver foil.

这种激光器不是由传统的镓和铟制造的，也不具有传统激光器的威力，但是是用这种材料制造的激光器很容易直接放置到任何物体的表面。

Organic lasers are not as powerful as traditional lasers made with gallium or indium compounds, but they can be easily printed or deposited directly on any type of surface.

金属镓在室温里是固体状态但是把它放在你的手上它就会融化，金属铯，元素钫这些比较稀有的元素在室温或者接近室温的情况下是液体状态的。

Gallium is solid at room temperature but will melt if held in your hand, caesium (Cs), and francium (Fr) ?the second rarest naturally occurring element, can also be liquid at or near room temperature.

Gallium arsenide switches ten times faster than silicon All of a sudden,I've got a clock speed ten times faster with no change in design.

砷化镓启动的速度是硅的10倍,突然，我得到了10倍快的时钟速度,但是设计没有发生任何改变。

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。
