摘要:

The viscosity of liquid hydrogen has been measured by observing its flow through a variety of capillary tubes. The resulting viscosities are about 10% higher than those obtained by Keesom and Macwood using an oscillating disc.

摘要:

This paper presents the results of experiments with shunt- and series-excitation of a 0.55 wave, uniform cross-section, vertical radiator. Both unattenuated field strength at one mile and fading characteristics at remote points were determined for each mode of excitation. Whilst Morrison and Smith have already done similar work with a non-uniform cross-section tower, this is the first attempt to examine the fading of a uniform cross-section tower excited in the two modes.
