n: See mist.

a suspension of fine liquid droplets or solid particles in a gas.

n: a group of two or more particles held together by strong forces. Aggregates are stable with normal stirring, shaking, or handling;they may be broken by treatment such as ball milling a powder or shearing a suspension.

n: A group of two or more individual particles held together by strong forces. Aggregates are stable to normal stirring, shaking or handling as powder or a suspension. They may be broken by drastic treatment such as ball milling a powder or by shearing a sus

n: a motor-driven paddle or blade used to mix the liquids and solids in drilling mud.

n: A mechanically driven impeller used to stir the drilling fluid to assist in the suspension of solids, blending of additives, and maintenance of uniform consistency.

a viscosimenter use for some fluid measurements, particularly when solid suspension properties are needed.

n: a heavy, flanged steel fitting connected to the first string of casing. It provides a housing for slips and packing assemblies, allows suspension of intermediate and production strings of casing, and supplies the means for the annulus to be sealed off. Also called a spool.

n: the curve assumed by a perfectly flexible line hanging under its own weight between two fixed points. A suspension bridge is an example of a catenary structure;an anchor chain is a catenary.

the first appearance of microsized paraffin crystals in suspension in the oil.

n: 1. a substance whose particles are so fine that they will not settle out of suspension or solution and cannot be seen under an ordinary microscope. 2. the mixture of a colloid and the liquid. gaseous, or solid medium in which it is dispersed.

n: A particle smaller than 2 microns. The size and electrical charge（电荷） of these particles determine the different phenomena observed with colloids, for example, Brownian movement.

a substance with particle size so fine that it exists as a stable dispersion rather than settling out.

n: a colloidal suspension containing one or more colloidal constituents.

n: finely divided particles of ultramicroscopic size suspended in a liquid.

n: The system that superfine particle suspend in the liquid media steadily and homogeneously. For example, cement slurry.

a dispersion of fine particles, held by charge or other force in a stable suspension.
