| 中文摘要 | A local horizontal electric field is able to retard the flow of nickel granule down a vertical pipe. In the first sequence of our experiments, the granule is released from a hopper after a voltage difference V is applied across two short, vertical copper electrodes. As V is increased from zero to 4.8 kV, Q remains practically constant for V < V-1, At V = V-1, Q drops abruptly; the drop depends on the location of the electrodes. Q then decreases gradually for V > V I, In the second sequence of our experiments, V is first set at 4.8 kV; the flow is allowed to start; then V is reduced to the desired voltage. The new Q vs. V curve coincides with the previous Q(V) curve of first sequence, except for V-2 < V < V-1. A simplified one-dimension model is able to explain all the observed features. |
