释义 | anode noun[ C ] electronics specializeduk /ˈæn.əʊd/ us /ˈæn.oʊd/ one of the electrodes (= objects that electricity moves through) in a piece of electrical equipment. The anode is the negative electrode in a battery and the positive electrode in an electrolytic cell.正极,阳极 Compare cathodespecialized Electrical components & circuitry accumulator AGM battery armature bandpass filter baseband chip cathode ray circuit breaker coil commutator conductor LED display multicelled multiconductor negative pole number pad OLED photoresist photovoltaic cell relay transformer It may act as an ion going wholly to the anode or cathode, but does not yield up its elements, except occasionally by a secondary action. The anode is treated in a special manner so as to render it non-porous and impervious to attack by the nascent chlorine evolved on its surface. The centre compartment is used to hold the lead or other suitable anode and electrolyte. The salt used, and also the anodes, were originally introduced into this country from America, and latterly from Germany. The silvery appearance of the deposit depends mainly on the purity of the salt as well as the anodes. anode | American Dictionaryanode noun[ C ] us/ˈæn·oʊd/ chemistry, physics one of the electrodes (= object that electricity moves through) in a piece of electrical equipment; the negative electrode in a battery and the positive electrode in most other electrical devices Examples of anodeanode This part was attached to a stepped-down anode of smaller radius. An aluminium foil of thickness 15 m was installed 20 cm downstream from the anode plane to separate the gas-filled region from the propagation zone. The other end of the anode holder is connected to the positive plate of the capacitor bank through an atmospheric air spark gap. Only a slight asymmetry exists between anode side and cathode side. The flow then exits the collimator shock and a jet is launched into the region above the anode plate. Distribution of the electron density becomes strongly nonuniform from the cathode to anode along the gap length. This figure shows the beam divergence angle along the anode radius. While the new electron subsequently starts to accelerate toward the anode, it leaves behind the ion which moves relatively slowly toward the cathode. The electric field is decreased in the channel, and it is enhanced near the anode. The total magnetic field pressure at the anode edge of the constriction is higher than at the cathode edge. In the limiting case, this barrier coincides in height with the potential barrier for the electrons going away toward the anode. Since cathode spots are sources of intense electron emission, their operation is governed by the closing of the electron current onto the anode. They have a finite and negative density gradient, and extend from the cathode to the anode. As this takes place, the current of the electrons arriving at the anode decreases by the value of the emission current. This design uses a long hollow anode of dimensions 300 80 40 mm.
