中子星的速率,得到轨道的半径，得到周期的大小，如之前讨论过的那样，现在取一个光学的。
That means you can get the speed of the neutron star, you can get the radius of the orbit, and you can get the period, just like we discussed before.
稀土合金膜具有优异的化学性质及其磁学、光学与俘获热中子等性能，为其广泛应用提供了基础。
Rare earth alloys have many desirable chemistry and magnetism behaviors, unusual optical and seizing thermal neutron properties, which provide the foundation for their applications.
