A label required on shipments of flammable articles.

The potential of a reversible oxidation-reduction electrode measured with respect to a reference electrode, corrected to the hydrogen electrode, in a given electrolyte.

Ratio of the pressure of a gas to its critical pressure, in like units.

Is the ratio in absolute units of the actual gas temperature to the critical temperature.

A compound that causes reduction, thereby itself becoming oxidized.

A reaction in which there is a decrease in valence resulting from a gain in electrons. Contrast with oxidation.

In general, the transformation of data from a "raw" form to some useable form. In meteorology, this often refers to the conversion of the observed value of an element to the value which it would theoretically have at some selected or standard level. The m ...

The gears that reduce engine speed to propeller speed.

To reduce the area of a sail by making fast the reef points (used in rough weather).

(1) The rolled up part of a sail, tied with the reef lines, that is used to reduce sail area for heavy winds; To reduce the sail area. (2) A group of rocks or coral generally at a depth shallow enough to present a hazard to navigation.

Reinforced cringles or thimbles in the sail designed to hold the reefing lines when reefing the sail.

Also known as the square knot, it is formed by two half hitches in which the ends always fall in line with the outer parts. This knot is used to loosely tie lines around the bundles of sail that are not in use after reefing.

Short pieces of line fastened to the sail at reef points, used for tying a reef to reduce sail area. The reef line will pass through reef cringles, which will become the new tack and clew of the reefed sail.

Short lengths of line attached to the sail used to tie the extra sail out of the way when reefing.

Refrigerated Cargo Ship or Container

Refrigerated container.

The operation of reducing a sail by taking in one or more of the reefs.

Refrigeration

A nonpolarizable electrode with a known and highly reproducible potential used for potentiometric and voltammetric analyses. See also calomel electrode.

The range of operating conditions of a device within which operating influences are negligible. The range is usually narrow. Reference operating conditions are the conditions under which reference performance is stated and the base from which the values o ...
