| Abstract: | In this paper,the research is made on the measurement of the unequal precision of the amount of time in air cushion orbit experiment.The change of single- tube photoelectric door to two-tube photoelectric door is done,effecting the measuremenr of time in the meantime.When the two-tube photoelectric door is applied to the law of conservation of momentum.the satisfied results are obtained. |
