(3) The selection of
Z_{max}

Let Z_{v} = 1, the
results computed by using formulae outside the sphere are listed in Table 3. It
can be seen from Table.3 that

Z_{max}
= 5.0 - 8.0
r_{s}=4.0 - 4.6

For H = 68
and M = 1
we have Z < 5.78, therefore the QSOs of
Z > 5 may be observed.
But Z > 8 is not observed in any way. If we cannot find _{
}
Z=5.78 QSO, or Z > 5.78 QSO is
discovered, then the group of parameter adopted by me must to change.
