Sulla realizzazione di due pendoli a breve periodo per sismografi orizzontali e verticali ad amplificazione ottico-galvanometrica
Main Article Content
Abstract
There are described two short period pendulums for
horizontal- and vertical- component seismographs (electromagnetic and
optical magnification) of the Galitzin type. In this first paper there are
explained the rules to follow for an easy construction of the pendufuins
and for the performance of the seismograpliical unities for a time already
in function in some Itahan Stations.
