＜正＞ The calibration of the big pad is important and necessary for the study of the knee structure of cosmic ray spectrum in ARGO-YBJ group. In this topic, some parameters of the electron beams of IHEP have been presented;based on these parameters and the requirements of ARGO-YBJ experiment, some questions together with possible solutions have been given;it is concluded that the calibration of the big pad with electron beams of IHEP is possible.

Due to its diverse bonding hybridization forms (sp, sp2and sp3), amorphous carbon exhibits multifaceted properties and important application prospects, which have aroused extensive research interest[1–5]. In amorphous solids, some degree of atomic short-to medium-range order is thought to be ubiquitous, and the recent synthesis of new amorphous carbon has further increased our understanding of the atomic disorder in materials [4].
