查询词典 missing value

The instantaneous current capacity may demonstrate through the nixietube, provides the craft data reference for the operator.8031If the system the setting value carries on again the current capacity actual value the comparison, calculates the control quantity after the PID adjustment operation vi, again transforms into the electric current output signal, after but controls the silicon-controlled rectifier after the enlargement the breakover angle, the realization adjusts the slippery difference electrical machinery magnetic clutch exciting current the function, thus the adjustment implementing agency slippery difference electrical machinery rotational speed, causes to transport on the leather belt the material current capacity to stabilize as far as possible nearby the setting value, and has the good static target and the dynamic performance.
