low-density

基本解釋

While Burchard was experimenting with refrigerator insulation, he came up with a novel way of molding low-density foam.
那年伯查德正在做有關(guān)冷凍機隔熱材料的實驗，實驗中他使用新的方法做出一種低密度的泡沫材料。
The main culprit, LDL (for low-density lipoprotein), is the body's oil truck, circulating in the blood, delivering fat and cholesterol to the cells.
主要的“罪犯”是低密度脂蛋白膽固醇，它是身體的運油車，在血液里向細胞傳輸脂肪和膽固醇。
The face of Spencer lit up with a logical scientific conclusion: the melted candy bar, the popcorn, and now the exploding egg, were all attributable to exposure to low-density microwave energy.
而斯賓塞腦中卻激發(fā)出一連串推論：融化的糖塊、爆米花、以及此刻這炸開的雞蛋，都是由于暴露在低密度的微波能之下。

So, for example, we have this average level, and then it can go high where we have the peak, or it can go very low. We can also discuss sound waves, so again it's just the periodic variation of some property -- in this case we're talking about density, so we have high density areas and low density areas.
例如這是平均位置，在峰的位置水位高，在谷水位低，我們也可以,討論聲波它也是某種,量的周期變化，在這里我們,討論的是密度,我們有高密度區(qū)和低密度區(qū)。

You can see down here its affect on cholesterol levels: that the bad fats raise the LDL levels, the low-density lipoproteins levels, that's not good for you.
在下面你可以看到它對膽固醇含量的影響,壞脂肪會提高LDL含量,低密度脂蛋白含量,這是對身體不好的

There are different kinds of cholesterol, and the first cut that people made at this were saying that there are things called HDL and LDL, which is high-density lipoproteins and low-density lipoproteins, the LDL.
膽固醇分為許多種,人們分離膽固醇時,最早得到的餾分是HDL和LDL,HDL即高密度脂蛋白,LDL即低密度脂蛋白
