摘要：

We present a design for large rotating liquid mirrors. These mirrors are stiff lightweight structures designed to support a thin reflective mercury surface layer. The general design features and fabrication techniques are described and approximate analytic formulas are derived describing the flexural, vibrational, and stability characteristics of these mirrors. As an example, we describe in detail the 2.7-m mirror of the UBC/Laval liquid mirror observatory. We conclude by considering the feasibility of employing this design for very large liquid mirrors.
