It's a loosely bound rubble pile as DART's closing images showed.

如 DART 的近距离图像显示的那样，它是一个松散结合的碎石堆。

It was also very low density, just what you'd expect for a loosely bound rock pile.

它的密度也很低，正如你所想象的的松散的岩石堆。

Open clusters are loosely bound collections of dozens or thousands of stars, usually in an irregular shape.

开放星团是由数十或数千颗恒星松散结合而成的集合体，通常形状不规则。

Conductors like metals and salt water tend to have loosely bound outer electrons, which can easily flow between molecules.

金属和盐水等导体往往具有松散结合的外层电子，这些电子很容易在分子之间流动。

The metal door knob's loosely bound electrons hop to your hand to replace the electrons your body has lost.

金属门把手松散结合的电子会跳到您的手上，以替换您身体丢失的电子。

A neutron star can feed on a lighter companion, gorging on its more loosely bound atmosphere before eventually collapsing cataclysmically into a black hole.

中子星可以以较轻的同伴为食，狼吞虎咽地吞下更松散的大气层，最终灾难性地崩解成黑洞。

Instead, they're stuck in a loosely bound high-energy state and are dying to move to a more stable lower energy state, which means releasing a lot of pent-up energy in the process.

相反，它们处于一种松散约束的高能量状态，并且极其容易向更稳定的低能量状态转变，这就意味着在这个过程中它们会释放大量封存的能量。

But electrons are tiny and almost insignificant in mass, and rubbing or friction can give loosely bound electrons enough energy to leave their atoms and attach to others, migrating between different surfaces.

但电子很小， 质量几乎微不足道，摩擦或摩擦可以为松散结合的电子提供足够的能量，使其离开原子并附着在其他原子上，在不同表面之间迁移。
