This is a list of Goa'uld technologies in the ''Stargate'' franchise. The Goa'uld are the main adversaries for most of the run of ''Stargate SG-1''. They scavenged or conquered most of their advanced technologies from other races. However, there are innovators amongst the Goa'uld; Anubis and Ba'al in particular have been depicted with a great deal of technological ingenuity. Rather than being designed as practical, many Goa'uld devices, such as the staff weapon, are designed to have higher visual impact, meant to intimidate and reinforce their position as gods to their followers. Some pieces of Goa'uld technology, such as the hand device and the healing device, respond only to mental commands and require naqahdah in the bloodstream of the user to operate. == Cloaking and shielding == * Cloaking device – The existence of Goa'uld cloaking technology is first revealed in , when Nirrti uses a personal cloaking device based on Reetou phase-shifting. Yu is outraged that she has not shared this technology with the System Lords. Personal cloaking devices have also been used by Hathor, and an ash'rak assassin. Cloaking devices first appear on a Goa'uld cargo ship in , and in later episodes become commonplace for Tel'taks and Al'kesh. In , Apophis cloaks an entire fleet of Ha'taks, a feat that Selmak says has never before been accomplished. (Actually it is first used by Hathor in "Hathor" then again in "Into the Fire"). * Force shield – An energy barrier, also called a force-field or simply a shield. Goa'uld force shields work on a frequency oscillation principle, so a fast-moving object can bypass it at the right moment. Goa'uld motherships are protected by force shields,〔 as are some ground-based facilities.〔 Force shields are also installed inside ships to restrict access to certain areas, and to contain hull breaches. Some powerful Goa'uld are equipped with personal force shields activated with a button on their hand device. These shields react proportionally to the amount of kinetic energy of incoming matter, blocking fast-moving objects like bullets but not slower objects like an object thrown by hand. This is so the shield does not stop air from getting in. The Tok'ra have made force shield technology available to the SGC. The Lucian Alliance has also obtained shield technology, and it appears to block any solid object, regardless of velocity. * Gate Shield – A force field that blocks a Stargate from unauthorized access, functioning similarly to Earth's Iris, though it does not impede the energy-absorbing armor of a Kull Warrior.〔 It can be deactivated remotely by a specific code. Planets with shielded Stargates include Tartarus〔 and Erebus.〔 * Sun shield – A pair of devices on P3X-513 designed to generate a massive force-field that protects the area below from ultraviolet radiation. It turns the sky orange as a side-effect. The device is reactivated by SG-1, in the process disproving former SGC officer Jonas Hanson's claim of divinity that he had used to seize power on the planet. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Goa'uld technology in Stargate」の詳細全文を読む スポンサード リンク
