We usually try to combine this sodium carbonate with the bleaching solution and precipitate out a powder.

我们通常尝试把这种碳酸钠和经过漂白的溶液结合，然后沉淀出粉末。

Every summer, as the surface waters warm, flakes of calcium carbonate precipitate out and drift to the bottom.

每年夏天，随着表层海水变暖，碳酸钙薄片沉淀出来，沉向海底。

Gold quickly precipitates out with the addition of a little water.

加入少量水后，金子很快就沉淀出来。

As seawater comes in contact with these surfaces, metals dissolved within it precipitate out to form a crust over the rocks.

当海水与这些表面接触时，溶解在其中的金属会沉淀出来，在岩石上形成外壳。

Alright, as a quick recap, nephrolithiasis is the formation of kidney stones, which form when solutes precipitate out into crystals in the urine.

得！快速回顾一下：nephrolithiasis是指有肾结石形成；肾结石在溶质于尿液中沉淀成晶体时形成。

And the right side shows sodium and nitrate still as separate ions in solution with the silver chloride precipitated out as solid.

右侧显示钠和硝酸盐在溶液中仍然是分离的离子，氯化银以固体形式沉淀出来。

The first type, as you might guess, are made mostly of cholesterol that has precipitated out of the bile as a solid and formed these solid stones.

正如你所猜想的那样，第一种结石主要由胆固醇构成；胆固醇以固体形式从胆汁中沉淀出来，形成这些结石。

If the iron carbonate has a little bit of sulfur in it then the sulfur tends to precipitate out as a kind of yellow powder.

如果碳酸铁中含有少量硫，那么硫往往会以黄色粉末的形式沉淀出来。

Thrombin then turns factor I or fibrinogen, which is soluble, into factor Ia or fibrin, which is insoluble and precipitates out of the blood at the site of injury.

之后凝血酶将可溶的因子I（纤维蛋白原）转变为因子Ia（纤维蛋白原），纤维蛋白不可溶，便在损伤部位从血液中析出。

So when that hot water gushes back out from the vent, it interacts with the cold water around it, and all those dissolved metals precipitate back out of the liquid.

因此，当热水从通风口喷出时，它会与周围的冷水相互作用，所有溶解的金属都会从液体中沉淀出来。

Perhaps, too, the fact that she was new to their world acted as a sort of catalytic agent to precipitate out all their old reservations about one another.

也许，她对他们的世界是陌生的，这一事实也起到了一种催化剂的作用，促使他们消除了对彼此的所有旧有保留意见。

Other inflammatory processes can also be a cause, like acute pancreatitis because free fatty acids end up binding to ionized calcium, which is also insoluble and precipitates out as a soap-like substance.

其它炎症过程也可能引发低钙血症，例如急性胰腺炎，因为游离脂肪酸最终与离子钙结合，形成不溶于水的物质，并以类似肥皂状物质的形式沉淀。

Multiply 58.45 grams per mole by 0.288 and we find: we need 16.8 grams of sodium chloride to precipitate out 1 troy ounce of silver out of silver nitrate solution.

将每摩尔 58. 45 克乘以 0.288，我们发现：我们需要 16. 8 克氯化钠才能从硝酸银溶液中沉淀出 1 金衡盎司的银。

Kidney stones form when solutes in the urine precipitate out and crystalize, and although these most commonly form in the kidneys themselves, they can also form in the ureters, the bladder, or the urethra.

当尿液中的溶质析出、结晶时会形成肾结石，它们大多在肾脏中形成，但在输尿管、膀胱、尿道中也可形成。

Another way crystals could form is from decreased clearance of uric acid, which can result from dehydration from not drinking enough water or from consumption of alcoholic beverages, both of allowing uric acid to precipitate out.

结晶的另一种成因是尿酸清除减少，如由饮水过少引起的脱水、大量饮酒等，这都会让尿酸更容易析出。

You do this slowly to admire the way it changes color, from green to a more milky hue, as it louches, or what happens when the essential oils precipitate out of the solution and release their aromas.

你慢慢地这样做， 欣赏它变色的方式，从绿色到更乳白色的色调，或者当精油从溶液中沉淀出来并释放香气时会发生什么。
