  "abstract": "We investigate the low-temperature properties of the spin-1 antiferromagnetic Heisenberg chain with bond-alternation by the quantum Monte Carlo method (loop algorithm). The strength of bond-alternation at the gapless point is estimated as $\\delta_{c}=0.2595\\pm0.0005$. We confirm numerically that the low-temperature properties at the gapless point are consistent with field theoretical predictions. The numerical results are compared with those of the spin-1/2 antiferromagnetic Heisenberg chain and recent experimental results for [\\{Ni(333-tet)($\\mu$-N$_3$)\\}$_n$](ClO$_4$)$_n$ (333-tet=tetraamine $N,N^{\\prime}$-bis(3-aminopropyl)-1,3-propanediamine).",
