The apparent arrow of time emerges as a property of the macroscopic system, but it's not there in the laws that govern the individual particle interactions.

很显然时间箭头成为了宏观系统的一种性质，但没有定律来控制单个原子间的相互作用。

Researchers also calculated a property known as the cross-section, which describes how likely the particle is to interact with others.

研究人员还测算出了一个名为横断面的暗物质的特性，横断面剖析描述了粒子之间相互作用的可能性的大小。
