Now when you look at uranium crosssection as a function of energy and that's this neutron energy from EVs to MEV levels.
现在，当你看铀的横截面，是以能量的函数，那是中子能量，从电子伏到兆电子伏水平。
2
Neutron lifetime is inversely related to capture crosssection.
中子寿命与俘获截面是倒数关系。
3
Zircaloy - 4 is generally used as fuel tubes in pressurized water reactors because of it " s low neutron absorption cross - section, excellent corrosion resistance, good strength and ductility".
