| restrained beam | In dentistry, a beam that has two or more supports, at least one of which permits some freedom of rotation to the point of support but not as much as if the support were a free support. (05 Mar 2000) |
|---|---|
| continuous beam | In dentistry, a beam that continues over three or more supports, those supports not at the beam ends being equally free supports. (05 Mar 2000) |
| horizontal beam film | A radiograph made with the central axis of the X-ray beam parallel to the floor, able to show an air-fluid level. (05 Mar 2000) |
| simple beam | In dentistry, a straight beam that has only two supports, one at either end. (05 Mar 2000) |
| neutral axis of straight beam | The axis perpendicular to the plane of loading of a beam at stresses within the proportional limit; it lies at the gravity axis of the cross-section of the beam. (05 Mar 2000) |
| neutral beam injection | <radiobiology> This is one of the fundamental plasma heating methods. A particle accelerator is used to create fast ion beams (the particle energies are on the order of 100 keV), the ion beam is then passed through a neutral gas region, where the ions neutralise via charge-exchange reactions with the neutral gas. The neutralised beam is then injected into a magnetically confined plasma. The neutral atoms are unaffected (not confined) by the magnetic field, but ionize as they penetrate into the plasma. The high-energy ions then transfer some of their energy to the plasma particles in repeated collisions, and heat the plasma. (09 Oct 1997) |
| electron beam | <microscopy> A stream of electrons in an electron optical system. (05 Aug 1998) |
