real expansion的意思|示意

Real refrigerators actually work with liquids that go into gases so use the latent heat of the liquid, so it doesn't really work like the Joule-Thomson expansion. So this is real.

液体变成气体来工作，以运用液体的潜热，所以这不是，真正像焦耳-汤姆逊膨胀一样工作，这是真实的气体，不像焦耳。

OK, so will this or any certification scheme solve the real problems that unchecked biofuel expansion is having in some parts of the world?

这样的话，在世界某些地区，存在于不受限的生物燃料扩张中的现实问题，这个认证计划或者其他任何认证计划能否解决呢？

But to make it real, to achieve the economic expansion we all seek, we need to unlock a vital source of growth that can power our economies in the decades to come.

但要实现这一愿景，实现我们大家所寻求的经济增长，则需要开启一个能使我们的经济在未来数十年中获得动力的必不可少的增长源泉。
