摘要：
A hadron mass calculation is reported using two flavors of dynamical, staggered fermions with masses of ma = 0.01, 0.015, 0.02, and 0.025 on a 16(3) x 32 lattice. The masses of hadrons containing valence quarks with ma = 0.004, 0.07, 0.1, 0.14, and 0.25 were also computed to study the limit ma ---> 0 and the strange particle spectrum. For ma = 0.01, the mass ratio m(N)/m-rho = 1.527(11) is 25% larger than experiment while the results f-pi/m-rho = 0.14(1) and (m(K)2 - m-pi-2)/(m(K)* - m-rho)m-rho = 2.25(3) agree somewhat better.
