物质粒子

" Colloid : Substance consisting of particles that, although too tiny to be seen with the unaided eye (typically 1 nanometre to 10 micrometres), are substantially larger than atoms and ordinary molecules and that are disperse d in a continuous phase."

胶体：由比原子或普通分子大得多，但远小于肉眼可见的微粒组成的物质。这种粒子的大小大约在10-7～10-3公分，并且以各种方式连接或键合在一起。

An instrument for measuring a property of light, especially luminous intensity or flux.

辐射由一种放射性物质发出的辐射，包括α粒子、原子核、电子、和γ射线

Long believed to exist in large quantities, it enters into many theories of the origin of the universe and its present large-scale structure and into models of gravitation and other fundamental forces between particle s.

长久以来相信有大量的暗物质存在，纳入许多宇宙起源与大尺度结构的理论，也进到重力及其它粒子基本力的模式之中。

"This is a story that may soon be at its end," Turner said, noting that the Cryogenic Dark Matter Search in the Soudan mine of Minnesota and other experiments below the ground should be sensitive enough to detect a WIMP.

特纳注意到明尼苏达州苏丹矿山里的低温暗物质搜寻计划及其他的地下试验非常精确灵敏，应该可以探测到弱作用重粒子，他说：情况可能很快就会有结果的。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
