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

但它也半渗透性的，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。

Saponins, which are found in soy, beans, peas, lentils, and other legumes are used as emulsifiers in the food and cosmetic industry and can damage the gut lining, making it more permeable or " leaky."

在大豆，豆类，豌豆，扁豆和其他豆类中含有皂苷，可能会损坏肠使其更具渗透性。

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.

织也需要进行类似的结合强度和渗透性的“外”测试，然后在猪身上进行临床测试，最终在类身上进行测试。

" The beads provide a very nice surface area and they're also porous so that the chemical reactions can take place on their surface and in the interior of these beads" .

" 这些微珠的表面积非常好，渗透性又好，因此其表面和内部都能发生化学反应。"

We also talked about how epithelial cells are polar, having both apical and basal sides, and are selectively permeable, and lastly we took a brief look at how our glandular epithelial tissue forms both out endocrine and exocrine glands.

我们还讨论了上皮如何极性的，具有顶端和基底两侧，并且具有选择性渗透性，最后我们简要了解了我们的腺上皮织如何形成内分泌腺和外分泌腺。

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.

免疫释放多种趋化因子，产生炎症反应，使上皮分泌更多黏液，并且使气管壁上的血管渗透性增加。

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，但研究员提出，小麦的某些部分促使肠道内壁变得更具渗透性。

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，因为也存在渗透性利尿，或因高血糖而引起的排尿增多。

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

另一种渗透性泻药通过使肠内的盐或糖的浓度，高于肠外的方式来奏效。

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

致敏肥大释放的胺通过增加周围毛血管的渗透性，最终导致面部织的充血水肿。

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

我还要了解积雪的深度、渗透性及硬度。

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

它们使用糖醇如麦芽糖醇来增甜，而麦芽糖醇一种强力的渗透性泻药。

Or you consume what's called osmotic sodium in water.

或者，你可以摄入所谓的渗透性钠于水中。

And I explored how porous is that?

我探究了这种渗透性有多强？

Gravity is, you know, we're being pulled towards the Andromeda Galaxy at some enormous rate of speed because of its massive counter-gravitational force to the force we exert on it.

你知道，引力所谓的四种基本力中最弱的一种，但它却具有最广泛的渗透性和最长的作用范围。引力，比如说，我们正以极高的速度被仙女座星系吸引过去，这因为它对我们施加的力的巨大反引力作用。因此，引力的作用范围极其广阔，但强度却异常微弱。

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.

当胺被释放时，它们会使您的毛血管（您内最小的血管）更具渗透性，从而使白进入毛血管并对抗过敏原。

And so it helps, I think, for us to understand that there is a porosity between human-controlled landscapes and non-human-controlled landscapes.

因此，我认为，这有助于我们理解类控制区域与非类控制区域之间存在着渗透性。

This, he said, presupposes an extreme permeability which would have to be demonstrated between upper-class culture and peasant culture.

他说，这预设了精英文化与农民文化之间必须证明存在着极端的渗透性。

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

它们真正具有渗透性的岩，可以很容易地储存地下水并充当供水。
