  We first presented an isochrone database that can be widely used for stellar
population synthesis studies and colour-magnitude diagram (CMD) fitting. The
database consists of the isochrones of both single star and binary star simple
stellar populations (ss-SSPs and bs-SSPs). The ranges for the age and
metallicity of populations are 0--15 Gyr and 0.0001--0.03, respectively. All
data are available for populations with Salpeter IMF and Chabrier IMF. Then
based on the isochrone database, we built a rapid stellar population synthesis
(RPS) model and calculated the high-resolution (0.3 AA) integrated spectral
energy distributions (SEDs), Lick indices and colour indices for bs-SSPs and
ss-SSPs. In particular, we calculated the UBVRIJHKLM colours, ugriz colours and
some composite colours that consist of magnitudes on different systems. As an
example for applying the isochrone database for CMD fitting, we fitted the CMDs
of star clusters M67 and NGC1868 and obtained their distance moduli, colour
excesses, stellar metallicities and ages. The results showed that the
isochrones of bs-SSPs are closer to those of real star clusters. The isochrone
database, colours, Lick indices of populations can be downloaded via
