受最近的一些宇宙线实验的启发，我们研究了味道平衡附近的奇异夸克物质的性质。利用费米气体模型，我们认为，与某些说法相反，夸克物质奇异体的几何半径并不比普通原子核的几何半径小，而是相当于普通原子核的几何半径。因此，我们提出了一种奇异小行星在大气中传播的情景，但仍允许它们深度穿透。
Motivated by some recent cosmic ray experiments, we study the properties of strange quark matter near flavour equilibrium. Using the Fermi-gas model we argue that, contrary to some claims, the geometrical radii of quark matter strangelets are not smaller than, but rather comparable to, those of ordinary nuclei. We propose, therefore, a scenario of propagation of strangelets through the atmosphere which still allows for their deep penetration.
