n: the spontaneous transformation of a radioactive atom into one or more different atoms or particles, resulting in a long-term transformation of the radioactive element into lighter, nonradioactive elements.

n: rate (commonly given in rpm) at which an action resulting from applied forces causes or tends to cause two adjacent parts of a body to slide relative to each other in a direction parallel to their plane of contact.

n pi: the compounds formed as a result of a chemical reaction, such as the reaction of an acid with rock. They may be solids (in which case they are called precipitates),liquids, or gases.

n: in an induction logging tool, a device that puts out electrical voltage, which is induced in the coil by eddy currents in a formation. The eddy currents are created by a transmi\ter coil on the logging tool. The amount of voltage induced in the receiver coil depends on the conductivity of the formation.

n: a device, driven by a clockwork mechanism, that provides a chronological record of gauge indications (e.g., by tracing values of pressure, vacuum, voltage) on a paper form.

n: the instrument which can record the measured data in the paper automaticly in chronological

n: the rectangle-shape bolting cloth made form single or manifold intersection silk

n: a device used to convert alternating current into direct current.

n: a permanent magnet meter with a rectifier built in to convert AC to DC.

v: to change an alternating current to a direct current.
