In order to broaden the application range, PEEK has been modified by 1064nm-wavelength pulse laser, then deposited with Ni-P alloys by electroless plating. The properties of metal layers on PEEK were characterized by SEM, resistance tester and metallographic microscope, respectively. When the laser energy density is relatively low (Q10J·cm-2), of which the surface resistance of the coating is less than 20 mΩ. In this paper, the interaction mechanism of the pulse laser on PEEK has been studied and the metals on the PEEK have been prepared under the laser-induced effect, which provides technical support for the future application of PEEK in aviation with aerospace fields, such as, radar and antenna.

In order to enhance the effectiveness of China’s water resources management, China has implemented the most stringent policies in recent years, such as the most stringent water resources management system, the full implementation of the “River Administrator” system, and the “Lake Administrator” system. In this article, we studied the water management systems of six foreign countries, including United States, Canada, Japan, the United of Kingdom, France, and Australia, with exploring and analyzing the operating modes of their management system, to summarize their distinct advantages and common problems, provide reference for the development and perfection of China’s water resources management system, and to better support the sustainable management of China’s water resources and water environment to support the sustainable economic development of the basin and strict water resources management systems and water Implementation of pollution prevention action plans.
