533 results about "Selection rule" patented technology

In physics and chemistry, a selection rule, or transition rule, formally constrains the possible transitions of a system from one quantum state to another. Selection rules have been derived for electromagnetic transitions in molecules, in atoms, in atomic nuclei, and so on. The selection rules may differ according to the technique used to observe the transition. The selection rule also plays a role in chemical reactions, where some are formally spin forbidden reactions, that is, reactions where the spin state changes at least once from reactants to products.

Ternary and multi-nary iron-based bulk glassy alloys and nanocrystalline alloys

InactiveUS20050263216A1High glass forming abilityIncreased electrical resistivityMagnetic materialsAmorphous phaseAtomic radius
Disclosed in this invention is a family of ternary and multi-nary iron-based new compositions of bulk metallic glasses which possess promising soft magnetic properties, and the composition selection rules that lead to the design of such new compositions. The embodiment alloys are represented by the formula MaXbZc, where M represents at least one of ferromagnetic elements such as iron and may partly be replaced by some other substitute elements; X is an element or combinations of elements selected from those with atomic radius at least 130% that of iron and in the mean time is able to form an M-rich eutectic; and Z is an element or combinations of elements selected from semi-metallic or non-metallic elements with atomic radius smaller than 86% that of iron and in the meantime is able to form an M-Z eutectic; a, b, c are the atomic percentage of M, X, Z, respectively, and a+b+c=100%. When 1%<b<15% and 10%<c<39%, the alloys show a bulk glass forming ability to cast amorphous ribbons/sheets at least 0.1 mm in thickness. When 3%<b<10% and 18%<c<30%, the alloys show a bulk glass forming ability to cast amorphous rods at least 1 mm in diameter. The amorphous phase of these as-cast sheets/rods is at least 95% by volume. This invention also discloses the existence of nano-crystalline phase outside of the outer regime of the bulk glass forming region mentioned above.

Method for mini-station to authenticate and log in virtual machine in cloud system and login system

The invention discloses a method for a mini-station to authenticate and log in a virtual machine in a cloud computing system and a login system. The method comprises the following steps that: (1) the mini-station logs in the cloud computing system by the login system; (2) the login system searches for the number of available virtual machines in the cloud computing system; (3) the login system starts the virtual machine in the cloud computing system according to virtual machine selection rules and executes steps (4) to (6) if the number of the available virtual machines is more than or equal to 1, otherwise returns information indicating that the cloud computing system does not have available resources to the mini-station, and the mini-station quits; (4) the virtual machine generates virtual machine login information, and transmits the virtual machine login information to the login system; (5) the login system transmits the virtual machine login information to the mini-station; and (6) the mini-station logs in the virtual machine. By the method and the login system, the mini-station can rapidly authenticate and log in the virtual machine, and the virtual machine is not required to be kept in a starting state so as to make safer the system and effectively save resources.
