Abstract: | Through formula and drawing ratio on experimental data measured,Study of electron and argon atom,frank -Hertz experiment different cathode voltage,the first grid voltage,reverse voltage,the anode current with the change of acceleration voltage. Analysis of anode current change rule and reason of observation of measured data,frank-Hertz curve drawing and find out the negative influence of experimental study the smal-lest cathode voltage,the first grid voltage,the reverse voltage reference value. |
