1. Random Error(Presystematic): Vaguely aware that there is systematic order. Stage of experimentation and inaccurate guessing
2. Emergent: In consistency in linguistic production. Begin to internalize certain rules. ‘U-shaped learning’. Unable to correct errors when they are pointed out. Avoidance of structures and topics.
4. Background

To understand XRD and analysis JCPDS card, we analyzed and studied the figure of XRD and did research and discuss background knowledge. Also we expect that we can find important information of XRD by doing experiment
Process of experiment
XRD is equipment that use characteristic X-rays. Through characteristic X-rays diffraction peak of material, we can examine closely unk
