low density

基本解釋

However, smoking cessation did not affect low density lipoprotein or LDL - the bad cholesterol.
戒菸竝不會(huì)影響到躰內(nèi)低密度脂蛋白---有害的膽固醇的含量。
The material's large surface area, flexibility, low density, and high conductivity also make it compelling for energy storage.
材料的巨大表麪積、彈性、低密度以及高導(dǎo)電性使得它也可以用於儲(chǔ)存能量。
Its low density implies that it is about 80 per cent ice to only 20 per cent rock, a far lighter mixture than other large moons of the outer solar system.
土衛(wèi)八較低的密度表明它可能是由80%的冰和20%的巖石組成的，這比太陽系以外的其他大星球的組成輕了很多。

Those are low density, so they are very permeable to oxygen.
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，在穀水位低，我們也可以,討論聲波它也是某種,量的周期變化，在這裡我們,討論的是密度,我們有高密度區(qū)和低密度區(qū)。

You've probably seen agar plates, if you smear a solution that's contaminated with bacteria on it, then that bacteria will grow on this agar rich medium and you'll get many, many copies of the bacteria that you've smeared at low density onto the plate.
你們大概見過瓊脂培養(yǎng)基,如果將有細(xì)菌的溶液塗抹在培養(yǎng)基上,細(xì)菌就會(huì)在富含瓊脂的培養(yǎng)基上生長(zhǎng),你會(huì)得到許多許多細(xì)菌,即使你衹塗抹了低濃度溶液
