Abstract: A method and system of digital circuit functionality recognition for circuit characterization is disclosed. In one embodiment, a method for determining the valid arcs includes receiving a truth table including state information associated with input pins and their associated output pins in the digital circuit. Valid arcs are then determined based on whether a change in each of the input pins causes a change in associated one of the output pins using the received truth table. A first arc table is then formed using state information associated with substantially the determined valid arcs. Redundant arcs are then identified in the first arc table using the associated state information. A second arc table is then formed by removing the state information associated with the redundant arcs from the first arc table.

Melted matte flows out from the chute, then gas is sprayed on the matte through spray facilities; the gas disperses the melted matte into a large amount of tiny liquid drops, and cools the dispersed tiny drops to semi-melted or solid copper grains; in the following dropping course, the copper grains are quenched by pressurized cold water; finally, copper grains drop to the cold-water pond along with the pressurized cold water for further cooling, and the produced sand-like mattes are sent to the next procedure through dehydration-and-transportation system. It can overcome explosion and prevent chemical reaction in quenching, reduce noise pollution, and has the properties of simple procedure and easy operation to settle the problems existed in water quenching of matte.

Abstract: This invention relates to a kind of devices with trace emission resulted for treatment of exhaust gas. The device comprises a vessel having only one opening that serves as inlet. At least two gas exchange sections in sequence are provided inside the vessel after inlet of exhaust gas, between two gas exchange sections there is a gas mixture chamber at their connection part. The gas exchange chamber at first gas exchange section has a through opening leading to outside atmosphere area. With this configuration, on entering into the gas exchange section, exhaust gas will be ejected inwards and causes very strong entrainment, which makes the gas chamber become vacuum and sucks air with oxygen from atmosphere into gas chamber via the through opening to atmosphere. Formed high-pressure gas is burned furiously with combustible gas in the gas chamber at next stage, and the remaining exhaust gas is transferred into next gas exchange section with very high-speed revolution occurring on exhaust gas and momentum transfer.
