Deflection Temperature Testing of Plastics. The deflection temperature is a measure of a polymer's ability to bear a given load at elevated temperatures. The deflection temperature is also known as the 'deflection temperature under load' (DTUL), 'heat deflection temperature', or 'heat distortion temperature' (HDT).
Coriolis effect. (mechanics). Also known as Coriolis deflection. The deflection relative to the earth's surface of any object moving above the earth, caused by the Coriolis force; an object moving horizontally is deflected to the right in the Northern Hemisphere, to the left in the Southern. The effect of the Coriolis force in any rotating system.
