| Abstract: | In the experiment of object motion around the vertical circle, the demonstrator's orbital structure is improved in a insulated metal bi-orbit. A needle chronometrical circuit of low voltage pulse is equipped, and the spots are taken down on the silk by electro-chemical indicator. Thus the problems in timing, velocity anylysis and record trace are solved. |
