Besides negative thermal expansion, the researchers also found that changes in temperature lead to a significant variation in the porosity of the material, which is therefore highly controllable.
除了负的热膨胀效应,研究人员也发现了温度改变引起的材料多孔性的明显改变,因而这种多孔性就变得高度可控。
Instead of expanding when heated — as is normally the case — the material contracts, a phenomenon known as negative thermal expansion.
与正常材料不同的是,当加热时,该材料不是膨胀,而是收缩,表现出负的热膨胀现象。
The expansion of the income gap has both a positive influence and a negative effect.
居民收入差距扩大对我国社会经济既有积极影响,也有消极影响。
pdv It's an isothermal expansion, so dw is just negative p dV.
因此dw等于负,这就是。
