Having little water in the lumen, creates a relatively high potassium concentration in the lumen.

水份较少时，管腔中钾离子浓度就会相应升高。

They can put out up to 100 lumens per watt.

它们可以输出高达每瓦 100 流明。

An equivalent CFL will get you way more, between 55 and 70 lumens per watt.

等效的 CFL 将为您提供更多，每瓦 55 至 70 流明。

Also, though, these vessels can relax or vasodilate, and the lumen's diameter increases, which allows more blood flow.

不过，这些血管也可以舒张，即血管舒张，以扩大管腔直径，让更多的血液流过。

Finally, there's an inner ring of luminal columnar cells, which are within the lumen or center of the gland.

最后是一层管腔柱状细胞，位于管腔内腺体中央。

This causes a decreased blood flow through its lumen, or hollow center.

这导致通过其内腔中空中心的血流减少。

The CR Revelation lighting package can produce up to 48,000 lumens in total, with as many as 27 LED lights.

CR Revelation 照明套件总​​共可产生高达 48,000 流明的光，配有多达 27 个 LED 灯。

So this means that phosphate is left in the lumen and eventually gets sent out in the urine.

这意味着磷留在了管腔内，最终通过尿液排出体外。

Bicarbonate helps neutralize the acidic chyme, and raising the pH in the intestinal lumen also helps digestive enzymes work more effectively.

碳能够中和性的食糜，还能提高肠腔内的pH值；这也可以提高消化酶的活性。

Different varieties of tracheostomy tubes include cuffed, non cuffed, double lumen tubes, tubes with speaking valves, metallic tubes, and so on.

不同种类的气管造口管包括带套囊的管、没有套囊的管、双腔管、带发声阀的管、金属管等。

In addition, these diuretics also allow more water to remain in the lumen, creating a relatively low potassium concentration in the lumen.

此外，这些利尿剂也允许更多的水保留在管腔内，造成管腔内相对低的钾浓度。

This means that phosphate is left in the lumen and eventually gets sent out in the urine.

这意味着磷留在腔内，最终通过尿液排出。

Both the cells of the tunica intima and tunica media generally get the nutrients they need from the blood in the lumen.

内膜和中膜的细胞，都能从管腔内的血液中获取所需的营养物质。

Now, that calcium's still in the lumen, but parathyroid hormone also affects the distal convoluted tubule and increases calcium reabsorption.

这时，钙仍然在腔内，但甲状旁腺激素也会影响远曲小管，增加对钙的再吸收。

A dissection is where the inner wall, or intima, gets a tear, and blood tracks into a false lumen in the vessel wall.

动脉内壁者说内膜产生撕裂，血流随之进入管壁的假腔中。

When an artery is in a state of vasoconstriction, the lumen of the artery gets smaller and blood flow decreases.

当动脉处于血管收缩状态时，动脉管腔变小，血流减少。

When the artery is in a state of vasodilation, the lumen of the artery gets bigger and blood flow increases.

当动脉处于舒张状态时，动脉管腔变大，血流增加。

Aldosterone increases sodium channels on the lumen side of the principal cell and sodium-potassium pumps on the basolateral side of the principal cells.

它增加主细胞腔面钠离子、钾离子通道和基底面的钠-钾泵的数量。

As the mucosa and epithelium are destroyed, blood and serum may be released into the lumen, which contributes to blood seen on the stools.

因为粘膜和上皮组织受到了破坏，血液血浆可流入肠腔当中，进而导致肉眼可见的血便。

Now, that calcium's still in the lumen, though, but parathyroid hormone also affects the distal convoluted tubule and increases calcium reabsorption.

现在，钙仍然在腔内，但是甲状旁腺激素也会影响远曲小管增加钙的再吸收。
