ADSORPTION

Adhesion of the molecules of gases, liquids, or dissolved substances to a solid surface, resulting in relatively high concentration of the molecules at the place of contact; e.g. the plating out of an anti-wear additive on metal surfaces.

HARMONIC CONSTANTS

The amplitudes and epochs of the harmonic constituents of the tide or tidal current at any place

FRETTING

Wear phenomena taking place between two surfaces having oscillatory relative motion of small amplitude.

ARMATURE BAR

Copper bars used in place of wire windings, in large armatures, generators, or motors.

HAVEN

A place of safety for vessels

GRID NAVIGATION

Navigation by the use of grid directions

HARMONIC ANALYSIS

The process by which the observed tide or tidal current at any place is separated into basic harmonic constituents. Also called HARMONIC REDUCTION.

HOMING

Navigation toward a point by following a signal from that point. Radiobeacons are commonly used for homing.

PORE

A small channel or opening in a filter medium which allows passage of fluid.

HYDRAULIC CURRENT

A current in a channel caused by a difference in the surface level at the two ends. Such a current may be expected in a strait connecting two bodies of water in which the tides differ in time or range. The current in the East River, N.Y., connecting Long Island Sound and New York Harbor, is an example.
