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

但它也是半性，可以让空和水分通过。

I need to know something about snow depth, about snow penetration or how hard the snow is.

我要了解积雪深度、性及硬度。

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

它是半性，意味着它可以让某些东西进出，但会阻止某些东西进入。

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

致敏肥大细胞释放组胺通过增加周围毛细血管性，最终导致面部组织充血水肿。

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

然而，增加性不仅会让白细胞进入，会让液体流出。

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

Another kind, osmotic laxatives, work by making the concentration of certain salts or sugars higher in your intestines than outside them.

另一种性泻药通过使肠内盐或糖浓度，高于肠外方式来奏效。

They’re sweetened using sugar alcohols like maltitol, which is a potent osmotic laxative.

它们使用麦芽糖醇等糖醇增甜，麦芽糖醇是一种强效性泻药。

In addition, soft soil has low strength, high compressibility, low permeability and low rheology.

此外，软土具有低强度、高压缩性、低性和低流变性。

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

它们是真正具有性岩体，可以很容易地储存地下水并充当供水。

And similarly, a congested nose is caused by the capillaries growing larger due to the increased permeability.

同样，鼻塞是由于性增加导致毛细血管变大引起。

Because hydrogels are permeable, you could deliver water-soluble drugs through the gel to the surface of the skin.

Dr. Patel says a gentler approach, and the one you probably want to start with, is called an osmotic laxative.

帕特尔博士说，一种更温和方法，你可能想从这种方法开始，被称为性泻药。

In this case, though, it's a slower process since there's also an osmotic diuresis or increased urination from the hyperglycemia, or high blood sugar.

尽管在这种情况下，过程较为缓慢，因为也存在性利尿，或因高血糖而引起排尿增多。

This doesn't necessarily mean gluten itself was causing illness but the researchers propose that some part of wheat prompts the intestinal lining to become more permeable.

这并不一定意味着麸质本身会导致疾病，但研究人员提出，小麦某些部分促使肠道内壁变得更具性。

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.

我意思是，虽然时间很长，但它有足够性，可以让空分子一一挤出来。

Immune cells release various chemokines which creates an inflammatory reaction that makes epithelial cells secrete more mucus and makes the blood vessels in the walls of the airways more leaky.

免疫细胞释放多种趋化因子，产生炎症反应，使上皮细胞分泌更多黏液，并且使管壁上血管性增加。

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结合强度和性“体外”测试，然后在猪身上进行临床测试，最终在人类身上进行测试。

When histamines are released, they make your capillaries—the smallest blood vessels in your body—more permeable, which allows white blood cells to enter the capillaries and fight the allergens.

当组胺被释放时，它们会使您毛细血管（您体内最小血管）更具性，从而使白细胞进入毛细血管并对抗过敏原。
