中文摘要：

为 strangelets 和奇怪的星的通常分开的处理现在为从 strangelets 到奇怪的星的目标与更全面的理论描述被统一。在根据 WittenBodmer 假设和脉冲星的观察 massradius 概率分发抑制模型参数以后，我们调查这种目标的性质。精力与增加 baryon 数字 monotonically 每 baryon 减少并且在最大的 baryon 数字到达它的最小，这被发现，相应于最巨大的奇怪的星。由于夸克弄空，一个电的潜力很好在夸克部分的表面上被形成。为一颗旋转的赤裸的奇怪的星，有在脉冲星的典型力量的一个磁场被产生。

英文摘要：

The conventionally separated treatments for strangelets and strange stars are now unified with a more comprehensive theoretical description for objects ranging from strangelets to strange stars. After constraining the model parameter according to the Witten-Bodmer hypoth- esis and observational mass-radius probability distribution of pulsars, we investigate the properties of this kind of objects. It is found that the energy per baryon decreases monotonically with increasing baryon number and reaches its minimum at the maximum baryon number, corresponding to the most massive strange star. Due to the quark depletion, an electric potential well is formed on the surface of the quarkpart. For a rotational bare strange star, a magnetic field with the typical strength in pulsars is generated.
