But it's also semi-permeable, allowing air and moisture to pass through it.

但它也是半渗透性的，可以让空气和水分通过。

It's semipermeable, meaning that it lets some thing pass in and out but blocks others.

它是半渗透性的，意味着它可以让某些东西进出，但会阻止某些东西进入。

They’re really permeable rock masses that easily store groundwater and act as a water supply.

它们是真正具有渗透性的岩体，可以很容易地储地下水并充当供水。

Is that fossilized air or is amber permeable enough that the air has been replaced?

是化石空气还是琥珀色的渗透性足以取代空气？

However increased permeability doesn't just let white blood cells in, it also let's fluids out.

然而，增加的渗透性不仅会让白细胞进入，还会让液体流出。

The IgE-primed mast cells release their histamine, which causes nearby capillaries to dilate - flooding the facial tissues with fluid.

致敏肥大细胞释放的组胺通过增加周围毛细血管的渗透性，致面部组织的充血水肿。

Similar " ex vivo" tests of the strength and permeability of the bond will also be needed for human tissue, followed by clinical tests on actual pigs and, eventually, humans.

人体组织也需要进行类似的结合强度和渗透性的“体外”测试，然后在猪身上进行临床测试，在人类身上进行测试。

I mean it's over a very long period of time but it has enough permeability for those molecules of air to squeeze out one by one.

我的意思是，虽然时间很长，但它有足够的渗透性，可以让空气分子一一挤出来。

Although they are similar to blood capillaries, lymphatic capillaries are more permeable, and therefore they're more prone to allow the passage of proteins or even larger particles such as bacteria and viruses.

尽管它们与血毛细血管相似，但淋巴毛细血管的渗透性更强，因此它们更容易使蛋白质甚至细菌和病毒等更大的颗粒通过。

So I know that when they, if you find certain crystals, the crystals have these fluid inclusions and sometimes air inclusions but from what I understand I think that the amber has enough permeability.

所以我知道，当你发现某些晶体时，晶体有这些流体内含物，有时还有空气内含物，但据我所知，我认为琥珀有足够的渗透性。
