NameUp Description Episode
D'Arsay archive1 A store of information left behind by the D'Arsay people.1 Masks
Dampening field2 A field which inhibits most forms of energy. Dampening fields can prevent weapons or communicators from working.2 The Doomsday Machine
Dark Matter3 Matter which is undetectable to most forms of sensor and scanner. Striking dark matter can cause normal materials to briefly phase out of space. Dark matter is commonly found in certain types of nebula,3 or in asteroid form.4 In Theory
Data clip5 A handheld information storage system used by the Kellerun.5 Armageddon Game
Data crystal6 An advanced information storage system used by the Idanians.6 A Simple Investigation
Data port6 A socket implanted into a person to allow them to interface directly with a computer.6 A Simple Investigation
Decompression chamber7 A sealed chamber used to gradually alter atmospheric pressure over hours or days.7 Space Seed
Deflector shield8 A force field projected around a space vessel or installation in order to protect it from attack. The effectiveness of shields varies greatly according to the type and frequency of weapon used.8 Mudd's Women
Dekyon9 A class of particles which travel below light speed.9 Cause and Effect
Delta radiation10 Form of highly hazardous radiation capable of causing severe disfigurement.10 Delta radiation could be used to stabilise liquid Trellium-D, though it was not wholly successful at this task.11 In the Mirror universe the warp core of the NX class starship emitted Delta radiation, and disfigurement was one of the hazards of being a Chief Engineer.12 The Menagerie, Part 1
Delta series radioisotopes13 A set of radioactive isotopes which are considered highly toxic to Humans.13 Visionary
Delta wave frequency14 An energy pattern generated by bothan ships.14 Riddles
Denevan crystals15 Contraband material which cannot legally be sold or owned within the Federation.15 The Sound of Her Voice
Dentarium16 A metal alloy which is used in the construction fo Vulcan spacecraft.16 Unification, Part 1
Desealer rod17 Device which unlocks pulsatel lock seal.17 Necessary Evil
Deuridium18 A substance capable of stabilising the cell structure of the Kobliad. Sources of deuridium were located in the Gamma Quadrant.18 The Passenger
Deuterium19 An isotope of the element hydrogen which is formed of one proton and one neutron orbited by a single electron.19 Relics
Deuterium control conduit20 A part of a Federation Starship's warp drive system.20 The Dauphin
Deuterium injector21 Element of a Starship's warp drive system.21 One Little Ship
Deuterium pumps22 Element of the drive system of an NX class starship.22 The Crossing
Diagnostic23 Starfleet term for a variety of procedures used to determine the nature of a fault in any system.23 The Child
Diamagnetic dust24 Substance to be found in the ring system of certain planets.24 Judgment
Diamagnetic minerals25 Naturally occurring substance found in igneous rock which can interfere with communications systems.25 Dawn
Diamagnetic storm26 Atmospheric storm which carried polaric energy. It was extremely dangerous to be caught in one.26 Vanishing Point
Diamide27 A metallic substance sometimes used in the construction of Bajoran earrings.27 The Search, Part 1
Diamond28 A form of carbon crystal, diamonds were relatively rare and were thus considered to be valuable in many cultures. Humans considered diamonds to be valuable up until 2367, with a large deposit constituting 'an incredible fortune'28, though Lithium crystals were worth three hundred times more than diamonds of equal weight.29 However, during 2367 the ability to manufacture large quantities of gem stones became widespread - so easy did this become, in fact, that a Constitution class vessel could manufacture diamonds by the ton. This rendered them worthless.28 Arena
Diboridium core30 A small power generator used by the Cardassians.30 Babel
Diburnium-osmium alloy31 A metal used in the construction of artificial planets by the Kalandans.31 That Which Survives
Dicosilium32 A substance used to create reflective coils in a Krieger wave convertor.32 A Matter of Perspective
Dicyclic warp signature33 Energy characteristic produced by Hirogen warp drive technology.33 Prey
Dielectric field34 A semi polarized magnetic field which can be used to overcome some forms of atmospheric turbulence.34 Innocence
Differential magnetometer35 A scientific instrument used by the Federation.35 Battle Lines
Dikironium36 A gaseous substance. Certain life forms are composed partially of Dikironium.36 Obsession
Dilithium chamber37 Element of a Federation warp drive which contains the dilithium crystals.37 Booby Trap
Dilithium crystal38 An element of Federation warp drives located within the warp core. Dilithium crystals control and regulate the matter/antimatter reaction which powers the vessel. Crystals should ideally be very pure, and very carefully aligned within the reaction chamber.38 Journey to Babel
Dilithium hydroxls39 Substance which could disable the warp drive of an NX class starship if it was mixed with ionized pyrosulfates and sent into the plasma vents.39 Precious Cargo
Dilithium matrix40 Element of the warp drive system of an NX class starship. During start up of the reactor the output had to be confined to within 300 and 312 millicochranes to prevent fusion of the dilithium matrix, unless the spatial-compression index was greater than 5.62% or the ship was within two parsecs of a Class-C gravimetric field distortion.40 Doctor's Orders
Dilithium sequencers41 Element of the warp drive of an NX class starship.41 The Catwalk
Dilithium vector calibrations42 A routine maintanence performed on the dilithium crystals of a Federation Starship. High accelerations are not advisable immediately after this procedure is performed.42 Brothers
Dimensional shift43 A form of transporter which uses space folding, thus rendering it virtually impossible to trace. The dimensional shift is damaging to DNA, and repeated use is fatal to living things.43 The High Ground
Directional sonic generator44 Handheld device which emits sound in a narrow beam.44 Playing God
Dispersion field45 Field which prevents the use of a transporter within a given area.45 Darmok
Displacement wave46 A spatial phenomenon which involves a polarized magnetic variation.46 Caretaker, Part 1
Distortion field47 A phenomena which occasionally exists in a planetary atmosphere. A distortion field prevents the use of transporters or shuttlecraft.47 Second Chances
Docking port48 An area on a vessels hull which allows it to physically link itself to any other object similarly equipped.48 Star Trek : The Motion Picture
Dolamide49 Chemical energy source used in power generators or, when very pure, in weapons.49 Dramatis Personae
Doppler compensator50 An element of the transporters which compensates for the relative velocities of the system and the object being transported.50 Generic canonical information
Drag coefficient51 A measurement of the frictional forces on a body travelling in a fluid relative to its speed.51 Imaginary Friend
Drake equation52 Theoretical equation proposed on 20th century Earth which attempts to estimate the number of civilizations in the galaxy.52 Future's End, Part 1
Drive coil assembly53 An element of a Federation impulse engine.53 Parturition
Drone54 Small flying device which the Son'a used in order to implant the Ba'ku with isolinear tags in order to facilitate transport.54 Star Trek : Insurrection
Drydock48 A large facility within which a Starship can be constructed, repaired or maintained.48 Star Trek : The Motion Picture
Dualitic convertor55 Tool used by Starfleet engineering specialists.55 Starship Down
Duck blind56 An observation post which is hidden behind a holographic projection that mimics natural surroundings. The federation employs Duck Blinds to observe primitive cultures without their knowledge.56 Who Watches The Watchers?
Duonetic field57 A type of energy which inhibits the operation of many technological devices.57 Paradise
Duotronics58 A computer technology created by Dr. Richard Daystrom which formed the basis of all computers in the mid 23rd century.58 The Ultimate Computer
Duranium10 Metal alloy used in the construction of Federation Starship hulls.10 The Menagerie, Part 1
Duratanium polyalloy59 A metal composite used in Federation Starship hulls.59 Dreadnought
