摘要：

I review the current status of lattice calculations of the properties of bound states containing one or more heavy quarks. Many of my remarks focus on the heavy-light leptonic decay constants, such as fs, for which the systematic errors have by now been quite well studied. I also discuss B-parameters, semileptonic form factors, and the heavy-light and heavy-heavy spectra. Some of my "world averages" are: f(B) = 200(30) MeV, f(B) root(B) over cap (Bd) = 230(40) MeV, f(Bs)/f(B) = 1.16(4) and f(Bs) root(B) over cap (Bs)/f(B) root(B) over cap (Bd) = 1.16(5).
