ground ring การใช้

• Fix an element \ delta \ in R in the ground ring.
• A 10-foot-high external wall and coils of barbed wire on the ground ring the building.
• For each label i \ in I, fix \ delta _ i \ in R in the ground ring.
• Atiyah originally proposed the axioms of a topological quantum field theory ( TQFT ) in dimension " d " defined over a ground ring ? as following:
• Matrices with generic noncommutative elements do not admit a natural construction of the determinant with values in a ground ring and basic theorems of the linear algebra fail to hold true.
• The ring ground is used as the base of the entire building's ground system, and all components of the building's ground system, including the building structure, are connected to the ground ring.
• They are also known as "'ground rings "', although this term may also be applied to grounding rings that are installed in metal pipe systems to protect electrical devices such as flow meters.
• A "'differential graded augmented algebra "'( or simply "'DGA-algebra "') or an augmented DG-algebra is a DG-algebra equipped with a morphism to the ground ring ( the terminology is due to Henri Cartan ).
• A session with Fermat usually starts by choosing rational or modular " mode " to establish the ground field ( or ground ring ) F as \ mathbb { Z } or \ mathbb { Z } / n.
• It may be a purely mechanical arrangement ( sensing the presence of the center pin of the plug ) or it can be a jack that notices when the ground ring of the plug shorts together two portions of the jack.
• When the ground ring is the integers or the Lie superalgebra is a free module, these conditions are equivalent to the condition that the Poincar? Birkhoff Witt theorem holds ( and, in general, they are necessary conditions for the theorem to hold ).
• When ground soil has poor conductivity, is very shallow, or non-existent, a grounding system can be augmented by adding ground rods, counterpoise ( ground ring ) conductor, cable radials projecting away from the building, or a concrete building's reinforcing bars can be used for a ground conductor ( Ufer Ground ).
