energy density

基本解釋

When hunger pangs become intolerable, try and assuage them with a relatively bulky food of low energy-density.
在饑餓折磨實在難忍時，想辦法吃些相對來說量大而能量密度低的食物。

This is a low energy-density device, which stores electricity directly by charging two conductive plates with static.
（和電池相比，）這是一種“低能量密度”設備，電能被直接存儲在兩塊靜止的導電板上。
Development of high energy-density power sources is urgently needed in many high-tech applications for solving the problems of environmental pollution and gradual depletion of fossil fuels.
發(fā)展高能密度化學電源是解決未來交通、環(huán)境和資源等一系列重大問題的關鍵技術。

So the fact is those lab animals have a hard-wired preference for foods that are high in fat and high in sugar, primarily because of the energy density that those foods bring to one, and then the variety is important because you get a mix of nutrients.
事實上實驗動物對高脂肪高糖的食物,有著強烈的偏愛,而這種愛基于,該類食物能給我們提供高能量,多樣性很重要,因為你能攝取多種營養(yǎng)
