摘要：

An new method for the measurement of the mechanical noise in stressed suspension fibers is proposed and realized. Excess noise above the thermal noise in the fundamental violin mode of thin tungsten wires stressed to greater than or equal to 20% of the break point is observed. Possible mechanisms of the excess noise are discussed and tentative recommendations for the design of the suspension of the mirrors in LIGO-type antennae are presented.
