Query: Inclusive Production of $h_c(h_b)$ States via $e^{+}e^{-}$ Annihilation   We calculate the inclusive production of $h_c(h_b)$ at $e^+e^-$ colliders
with the center-of-mass energy from the CLEO-c energy to $Z^0$ boson mass at
leading order of nonrelativistic QCD. At $Z^0$ boson mass, the cross sections
are $39\sim 703$fb for $h_c(1p)$, $37\sim 61$fb for $h_b(1p)$ and $44\sim 73$fb
for $h_b(2p)$. At the B-factory, it is $86\sim212$fb for $h_c(1p)$. For $h_c$
at the CLEO-c and $h_b(1p,2p)$ at the B-factory, the perturbative QCD expansion
is not good and the results are much smaller than the experimental
measurements. It is clearly shown in all the results that the color-octet state
$(^1S_0^8)$ contributes dominantly while the color-singlet state $(^1P_1^1)$
contributes small or even negative part, in contrast to the case of inclusive
$J/\psi$ production where the color-singlet state is found to contribute
dominantly.
