举一反三
- each series section of a series pipeline A: head loss equal B: total energy loss equal C: hydraulic gradient equal D: flow rate equal
- The positive sequence voltages of phase A, B, C are distributed in ( ) A: the same direction B: counter clockwise C: clockwise D: indeterminacy
- There are two identical batteries in series, which statement is true?( ) A: The total voltage equals the sum of the voltages of each battery. B: The total voltage equals any battery voltage. C: The total voltage equals half of one battery voltage
- Data _______ is a series of operation that are carried out on data. A: process B: processed C: processing
- The indirect decoding method means that the IO interface addressing requires at least two bus operations. The first bus operation outputs and latches the address through the data bus to the address port in the IO interface. The second bus operation can realize the communication of other ports of the IO interface.
