The National Major Scientific Instruments and Equipment Development Project, ''Research on Spherical Focusing Acoustic System'' Has Passed Acceptance

From March 20th to 24th, 2017, the final acceptance meeting for the National Major Scientific Instruments and Equipment Development Project, "Research on Spherical Focusing Acoustic System," was held in Chongqing. Academician Shen Yan, Vice Chairman of the National Natural Science Foundation of China, attended the meeting and delivered a speech. He emphasized that major instrument development projects are oriented towards scientific frontiers and national needs, guided by scientific objectives, supporting the development of original major scientific instruments and equipment, providing new means for scientific research, and promoting the development of emerging industries through basic research and scientific discovery. He hoped that the project acceptance expert group would conduct a thorough review of the project and provide an overall evaluation of the research team's five years of work.

The project final acceptance expert group consisted of 19 experts, including technical experts, members of the Expert Advisory Committee of the Medical Sciences Department, members of the Expert Committee of the National Major Scientific Instruments and Equipment Development Project, archive management experts, and financial experts. The group was divided into three subgroups: instrument testing, archive review, and financial acceptance, conducting acceptance work simultaneously.

The acceptance expert group listened to a report from Professor Wang Zhibiao of Chongqing Medical University, the project leader, on the project completion status and conducted on-site testing and review of the project completion, archive management, and financial execution. The expert review panel concluded that the project team established key technologies such as the design and fabrication of high-sound-pressure spherical sound collectors and the quantitative real-time measurement of high-sound-pressure sound fields. They achieved the main technical indicators, completed the core technology development and prototype development of the instrument, and the on-site inspection showed stable system operation. The project obtained the expected high-sound-pressure scientific experimental results and explored related biomedical applications under strong sound pressure conditions, potentially opening up new directions in acoustic chemistry, materials science, and physics research. The project, focusing on the development of a spherical sound collecting system, achieved a number of original research results, publishing 114 SCI academic papers and obtaining 48 authorized invention patents, including 29 Chinese invention patents and 19 international invention patents. It also participated in the formulation or revision of 5 international, national, industry, and local standards. The expert panel concluded that the project completed its research content, achieved its expected goals, and agreed to pass the acceptance review.

The head of the project acceptance panel, Academician Wang Weiqi of Fudan University, pointed out that this major instrument development project has significant original innovative characteristics, and the research content was extremely difficult to complete. Through five years of collaborative research, the project team overcame numerous difficulties and successfully completed the planned tasks. He expressed his hope that the project team would continue to work together after the project's completion, increasing the openness and sharing of domestic and international scientific research based on the spherical focusing acoustic instrument system, making it an open research platform in the field of high sound pressure levels as soon as possible; further improving the testing technology system and standards for 109 Pa-level high sound pressure levels; and conducting scientific research in the fields of biomedicine, physics, materials, and chemistry based on the spherical focusing acoustic instrument system to further reveal new phenomena and their mechanisms under high sound pressure conditions.

Relevant leaders from the Planning Bureau and Finance Bureau, as well as relevant personnel from the Department of Medical Sciences, attended the meeting.
