At the heart of Abancens' team's detector, which is called a scintillating bolometer and resembles a prop from The Golden Compass, is a crystal so pure it can conduct the energy ostensibly generated when a particle of dark matter strikes the nucleus of one of its atoms.

亚巴塞斯团队开发的暗物质探测器名为"闪烁辐射热测量仪"，外形酷似科幻大片《黄金罗盘》中的道具，核心是一个纯度极高的水晶体，可以传导暗物质粒子撞击其原子核时产生的能量。

He spent the next three years there working with Professors Van Vleck and Bridgman on problems in cohesion and electrical conduction in metals and also did some work on the level density of nuclei.

他又在那里和范弗勒克教授和布里奇曼教授工作了3年，研究金属的内聚性和电子传导，也做了一些原子核的水平密度研究。

Heavier nucleus was believed to be formed of a number of protons and electrons packed closely together.

人们相信，较重的原子核是由若干个质子和电子紧密聚集在一起而形成的。

This atom,with 92 electrons spinning about the closely packed and complex nucleus,is the element uranium,which seems to be the most complicated of the natural atoms.

这一有着92个电子围着又密集又复杂的原子核旋转的原子，就是元素铀。它似乎是天然原子中最复杂的原子了。

This atom,with 92 electro i ing about the closely packed and complex nucleus,is the element uranium,which seems to be the most complicated of the natural atoms.

这一有着92个电子围着又密集又复杂的原子核旋转的原子，就是元素铀。它似乎是天然原子中最复杂的原子了。句中with引出的是一个介词复合结构，作定语，修饰atoms。

An electron is an extremely small corpuscle with negative charge which rounds about the nucleus of an atom.

电子是绕着原子核转动带有负电荷的极其微小的粒子。

电子是绕原子核运转且带有负电荷的极其微小的粒子。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
