low-density

基本解释

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关冷冻机隔热材料的实验，实验中他使用新的方法做出一种低密度的泡沫材料。
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”是低密度脂蛋白胆固醇，它是身体的运油车，在血液里向细胞传输脂肪和胆固醇。
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.
而斯宾塞脑中却激发出一连串推论：融化的糖块、爆米花、以及此刻这炸开的鸡蛋，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.
例如这是平均位置，在峰的位置水位高，在谷水位低，我们也可以,讨论声波它也是某种,量的周期变化，在这里我们,讨论的是密度,我们有高密度区和低密度区。

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对胆固醇含量的影响,坏脂肪会提高LDL含量,低密度脂蛋白含量,这是对身体不好的

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.
胆固醇分为许多种,人们分离胆固醇时,最早得到的馏分是HDL和LDL,HDL即高密度脂蛋白,LDL即低密度脂蛋白
