格林兰单冰核心累集记录说明什么？
What do accumulation records of single ice cores in Greenland represent?
研究人员将他们的研究基于冰河时期陆地与海洋的表面温度，通过检查冰核心，钻井，海底沉积物和其他因素。
The researchers based their study on ice age land and ocean surface temperature obtained by examining ices cores, bore holes, seafloor sediments and other factors.
水分子连接成坚固的结构排布，这一小小的冰结构是雪花晶体的核心。
Water molecules join together in a rigid pattern - a tiny ice structure that's the heart of a snow crystal.
但最近对泰坦内部的一项新研究却揭开了这颗奇异星球更为怪诞的一面：脆弱的甲烷冰地表之下，覆盖着一层冰泥，更深处依然是一个地下海洋，最中间是冰和岩石并存的固态核心。
But a new look at Titan's insides reveals even more oddities: Beneath the brittle crust of ice lies a layer of slush. Deeper still is an underground ocean over a solid core of rock and ice.
所以土星也许曾经有过多个卫星-其中一个可能是由水冰外壳包裹着岩石核心构成。 。
So Saturn might once have had more—one of which could have had a rocky core surroundedby a shell of water ice.

海冰-结构的动力相互作用、冰激振动及冰载荷的识别问题，仍是目前工程海冰界的核心和热点问题。
Dynamic interactions of sea ice with offshore structures, ice-induced vibrations and ice loads identification, are still the hot and key problems in ice engineering.
她证明了土星的潮汐力强度能够满足将冰质幔层剥离而不伤害到硅酸盐核心的条件。
She demonstrates that the planet's tidal forces can indeed be strong enough to take water ice away from the satellite, but not to tear its dense silicate core.
拥有硅酸盐金属核心与冰质幔层的大量已分化小行星是最佳选择。
A large, differentiated satellite - with a core composed of silicates and iron, and a lighter mantle made of water ice - would be a good choice.
慧星是早期太阳系中冰、灰尘和岩石的聚合物。它的核心在形成后没有发生过物理、化学的变化。
Comets are conglomerations of ice, dust and rock from the early solar system, whose cores have remained physically and chemically unchanged ever since.
慧星的核心部位结合得很松散。当粘着它们的冰开始汽化时，它们很快就解体了。
The pieces of the comet's nucleus appear to have been loosely assembled, so that they broke apart soon after the icy "glue" in between began to vaporize.
