註釋

This research on steel diaphragms was undertaken at the Langley Memorial Aeronautical Laboratory as a part of a general investigation of fuel injection engines for aircraft. This work determined the load-deflection, load-deformation and hysteresis characteristic for single diaphragms having thicknesses from 0.002 inch to 0.012 inch, and for similar diaphragms tested in mulptiple having total thicknesses from 0.012 inch to 0.180 inch. The elastic limit loads and deflections, and rupture points of single diaphragms were also determined. Some work was done on diaphragms having central orifices in order to determine the effect of orifice diameter upon the load deflection characteristics.
