春晚魔术(国外英文资料)
春晚魔术(国外英文资料) 2011 spring festival magic secret: Goldfish square decryption Fish tend to use electricity to remote control: positive reaction of fish. DC electric field in certain strength in fish by current stimulation, the body will turn to the anode, anode and swim, and even the direction of current, the fish will turn towards the anode. In AC electric field in the fish stagnant. The directional electrical response of fish to electrical stimulation is called the positive reaction. The minimum or critical voltage corresponding to the positive response of the fish is called the positive voltage The voltage at which the fish heads to the anode is 1.5 - 2 times as long as the tail of the fish toward the anode The head and tail of middle voltage electric electric voltage value to stimulate the fish: fish head to the anode, the fish does not produce a sense of power to the anode reaction, fish, fish will produce a sense of electric response. This is why the fish in the field in motion towards the anode (i.e., the reaction is more positive) fish in order to reduce the shock instinct of pain. Individuals with large fish respond sensitively to low frequency pulse currents, and a small individual fish has a higher frequency of pulses to produce the same chemotactic response When the fish pulse is stimulated by higher frequency impulse, it can not get an effective reaction to the sun, and the fish usually produce a positive reaction, and the optimum pulse current frequency is about 40 Hz Anchovy small sardines hasten Yang pulse frequency of 25-45 Hz; finlet etrumeus 25-45 Hz; engraulisjaponicus 25-45 Hz; first 35 Hz; sole 20-40 Hz; carp 45-50 Hz When fish impulses are stimulated by a rapid increase in the waveform and a slow weakening of the fish, the fish immediately produce a positive reaction. The faster the current increases, the lower the voltage of the fish to produce the positive reaction When the slow current and rapid weakening of the pulse current stimulate the fi
