Abstract
A 10 m, thermally stabilized steel measuring base has been constructed in a deep underground laboratory. Length is maintained constant to at least 2 parts in 109per hour by an on-off temperature control system. Results are compared with those obtained from a similar base built in 1968, which was situated in a surface laboratory.Keywords
