摘要
A 12 m measuring base is described which is fabricated from steel tube using internal water circulation with an on-off control system to regulate temperature to 0·02 degC. Dimensional changes over several hours have been shown to be controlled to within 0·2 p.p.m. from continuous records made with a tensioned-wire deformation transducer capable of 0·01 μm resolution.
