time-of-flight method
1Time-of-flight — The time of flight (TOF) describes the method used to measure the time that it takes for a particle, object or stream to reach a detector while traveling over a known distance. In time of flight mass spectrometry, ions are accelerated by an… …
2Time-of-flight mass spectrometry — (TOFMS) is a method of mass spectrometry in which ions are accelerated by an electric field of known strength. [Stephens, W. E., [http://link.aps.org/abstract/PR/v69/p674/s2 A Pulsed Mass Spectrometer with Time Dispersion] Phys. Rev. , 1946, 69 …
3Time of flight diffraction ultrasonics — Time of Flight Diffraction (TOFD) method of Ultrasonic inspection is a very sensitive and accurate method for nondestructive testing of welds for defects. TOFD is a computerised system that was invented in the UK in the 1970s for the nuclear… …
4Time of Flight Ultrasonic Determination of 3D Elastic Constants — The three dimensional elastic constants of materials can be measured using the ultrasonic immersion method. This was pioneered by xx and xx from the National Physical Laboratory in the 19xx s. It has mainly been used for polymer composite… …
5Flight feather — Flight feathers are the long, stiff, asymmetrically shaped, but symmetrically paired feathers on the wings or tail of a bird; those on the wings are called remiges (singular remex) while those on the tail are called rectrices (singular rectrix).… …
6time-of-flightmass spectroscopy — time of flight mass spectroscopy (tīmʹəv flītʹ) n. A method of separating ions of different masses based on the time needed for the ions to traverse a fixed distance. * * * …
7Flight planning — A Tarom Boeing 737 300 and United Airlines Boeing 777 200 taxiing to depart London Heathrow Airport. Flight planning is the process of producing a flight plan to describe a proposed aircraft flight. It involves two …
8Flight and expulsion of Germans (1944–1950) — Flight and expulsion of Germans during and after World War II (demographic estimates) Background …
9Time dilation — This article is about a concept in physics. For the concept in sociology, see time displacement. In the theory of relativity, time dilation is an observed difference of elapsed time between two events as measured by observers either moving… …
10Flight data recorder — An example of a flight data recorder; the underwater locator beacon is the small cylinder on the far right. (English translation of warning message: FLIGHT RECORDER DO NOT OPEN) …
