摘要

Frequency measurements of ninety-one gold-plated resonators, fabricated , during the previous quarter, have been continued. These units were fabri¬cated similarly with the exception that the container types were varied. The number of units and the types of containers were as follows:n16 units in nickel-silver HC-6/U cans, double-electrocleaned; 19 units in nickel-silver HC-6/U cans, hydrogen-fired; 15 units in copper HC-6/U cans, double-electrocleaned;n5 units in copper HC-6/U cans, hydrogen-fired; 19 units in copper HC-6/U cans, enamel-lined; 12 units in glass containers, evacuated; 5 units in glass containers, argon filled.
