Spherical and whisker-like cobalt particles were doped into the diamond powders to synthesize the PDC compacts under the HPHT conditions, to investigate the effect of their morphology on the properties of PDC. It was found that the two morphologies of cobalt powder have significant differences in physical characteristics, such as microstructure, porosity, magnetic properties, and crystallinity. When they were used to synthesize PDC samples, it was found that there were noticeable differences in interface bonding morphology, abnormal growth of interface WC, impact strength, and wear resistance. PDC synthesized with spherical cobalt powder had better comprehensive performance than PDC synthesized with whisker-like cobalt powder.

As a pioneer part of the major project of space-integrated-ground information network (SIGN), the typical application services provided by the ground information port (GIP) are the basic starting point and footing point for the implementation of major project to serve our national strategy and economic construction.Based on the basic framework of the ground information port and the idea of cloud service construction, the typical case of the ground information port was explored, providing reference for the development of the related technical services in the ground information port.
