单位体积内的包含的能量，单位：焦耳/立方米，千焦/立方米，兆焦/立方米，量纲M(L^-1)(T^-2)。用来衡量电池最合适，比较单位体积的电池所储存的电量。气体燃烧热（以体积衡量的）实质上就是能量密度。简介 能量密度（Energy density）是指在一定的空间或质量物质中储存能量的大小。完全能量密度 此表给出了完整系统...
Tailoring the surface structure of Earth-abundant perovskite oxides can provide cost-effective, high-efficient, and durable electrocatalysts for oxygen evolution reaction (OER). However, the structural origin leading to high OER performance of perovskite is not fully understood. Here, we present a stra...

The spatial agglomeration of urban elements results in the center-periphery urban structure, but the difference in spatial gradients of socioeconomic and physical elements is unclear. This study investigates how urban land density (ULD) and nighttime light intensity (NLI) decline with the distance to...
Definition Except for iron meteorites, the Earth is the densest body in the solar system. As has been recognized for more than two centuries, it is, on average, about twice as dense as common surface rocks. But many of the early speculations on its internal structure were bizarre, ignoring...
