摘　　要：As recombination centers of vacancies(Vs)and self-interstitial atoms(SIAs),firstly grain boundaries(GBs)should have strong capability of trapping point defects.In this study,abilities to trap Vs and SIAs of eight symmetric tilt GBs in tungsten are investigated through first-principles calculations.
