查询词典 conical pendulum

Coning and quartering method: put the sample onto the steel plate in the form of a cone; each scoop shall be inserted from the top of conical to make it spread along the top evenly, and pay attention not to misplace the center of cone; do it at least 3 times and mixed thoroughly; then flatten the top and use the cross plate from top to bottom to divide into 4 equal segments, randomly take out 2 oppositesegments and do it repeatedly for several times and finally divided into not less than the minimum retained quantity.
