Abstract:
     The present invention relates to the technical field of processing and orienting crystal filter and other devices. A relation diagram for judging crystallographic-axis polarities has been drawn from the experiment and research of the relation between the distribution of the growth lines and the crystallographic-axis of LT crystal. When a polarized LT crystal is put on a plane and contrasted with the said diagram, its crystallographic-axis polarities may be determined accurately. The said method is fast, reliable and simple in operation.
