Then in 2003, NASA's space-based Wilkinson Microwave Anisotropy Probe (WMAP) mapped the CMB across the sky, producing an exquisite baby picture of the cosmos.

之后的2003年，NASA在太空中的“威尔金森微波各向异性探测器”（WMAP）为穿越天空的CMB绘制了映射图，为早期宇宙制做了一幅精确的照片。

The dependence of simulation results on the space step, the initial nucleus radius, anisotropy and undercooling studied, and how to choose the values of these parameters is settled.

研究了空间剖分步长、初始晶核半径、各向异性系数和过冷度对模拟结果的影响，确定了这些关键参数的取值范围。

Luckily, an anisotropy system can be treated as an isotropy system in fractional-dimension space, where the dimension is determined by degree of anisotropy.

引入分数维空间模型，可以把各向异性的系统转换为各向同性的分数维系统。
