用3000吨水切伦科夫探测器用两种独立的方法研究了磁单极子引起的核子衰变。在探测器中搜索多核子衰变给出了单极通量的截面和与速度有关的极限F M<；2.5×10-15 cm-2 S-sr-1(5×10-5<；βM<；10-3)和σ=100mb(90%C.L.).从太阳上搜索低能中微子(30<；Eν<；52 MeV)给出了一个极限，F M(σ0/1 mb)<；1.6×10-21(βM/10-3)2 cm-2 S-1 sr-1在90%C.L.
Search for nucleon decays induced by magnetic monopoles has been carried out with a 3000 ton water Cherenkov detector by two independent methods. Search for multiple nucleon decays in the detector gives the cross section and velocity dependent limits on the monopole flux, F M <2.5×10 -15 cm -2 s - sr -1 for 5×10 -5 <β M <10 -3 and for σ=100 mb at 90% C.L. Search for low energy neutrinos (30< E ν <52 MeV) from the Sun gives a limit, F M (σ 0 /1 mb)<1.6×10 -21 (β M /10 -3 ) 2 cm -2 s -1 sr -1 at 90% C.L.
