31Surface area — is the measure of how much exposed area an object has. It is expressed in square units. If an object has flat faces, its surface area can be calculated by adding together the areas of its faces. Even objects with smooth surfaces, such as spheres …
32Surface-mount technology — (SMT) is a method for constructing electronic circuits in which the components (SMC, or Surface Mounted Components) are mounted directly onto the surface of printed circuit boards (PCBs). Electronic devices so made are called surface mount… …
33Surface mining — is a type of mining in which soil and rock overlying the mineral deposit are removed. It is the opposite of underground mining, in which the overlying rock is left in place, and the mineral removed through shafts or tunnels. Surface mining is… …
34Surface charge — is the electric charge present at an interface, for instance on the surface of a semiconductor material, or for example, on the surface of a protein in water.There are multiple factors generating surface charge. First of all, surface charge… …
35Surface Mining Control and Reclamation Act of 1977 — The Surface Mining Control and Reclamation Act of 1977 (SMCRA) is the primary federal law that regulates the environmental effects of coal mining in the United States.SMCRA created two programs: one for regulating active coal mines and a second… …
36Surface engineering — is the sub discipline of materials science which deals with the surface of solid matter. It has applications to chemistry, mechanical engineering, and electrical engineering (particularly in relation to semiconductor manufacturing).Solids are… …
37Surface weather observation — Surface weather observations are the fundamental data used for safety as well as climatological reasons to forecast weather and issue warnings worldwide. [Office of the Federal Coordinator of Meteorology. [http://www.ofcm.gov/fmh 1/pdf/B CH2.pdf… …
38Surface — Sur face , n. [F. See {Sur }, and {Face}, and cf. {Superficial}.] 1. The exterior part of anything that has length and breadth; one of the limits that bound a solid, esp. the upper face; superficies; the outside; as, the surface of the earth; the …
39Surface condensation — Surface Sur face , n. [F. See {Sur }, and {Face}, and cf. {Superficial}.] 1. The exterior part of anything that has length and breadth; one of the limits that bound a solid, esp. the upper face; superficies; the outside; as, the surface of the… …
