Major scientific research instrument special "spherical focus sound collection system" passed acceptance

[China Instrument Network Instrument R&D] On March 20th to 24th, 2017, the National Key Scientific Research Instrument and Equipment Development Research Center “Study on the Ball Focus Collecting System” was held in Chongqing.

Academician Shen Yan, Deputy Director of the National Natural Science Foundation of China, attended the meeting and delivered a speech. He emphasized that major instrument research projects are oriented to scientific frontiers and national needs, guided by scientific goals, support the development of original scientific research equipment, provide new means for scientific research, and promote the development of emerging industries through basic research and scientific discoveries. . He hoped that the experts in the project acceptance group would conduct a careful and detailed review of the project and conduct an overall assessment of the research team's five-year work.

The project conclusive acceptance expert group consists of 19 experts including technical experts, members of the Expert Consultation Committee of the Medical Science Department, members of the National Special Scientific Research Apparatus and Equipment Development Specialist Committee, file management experts, and financial experts, which are divided into instrument testing, file review, and finance. Acceptance of 3 teams at the same time carry out acceptance work.

The acceptance expert team heard the project completion report of Prof. Zhizhe Wang from Chongqing Medical University and conducted on-site testing and review of project completion, file management, and financial performance. The acceptance panel believes that the project team has created key technologies for the design and processing of high sound pressure spherical sound collectors, real-time quantitative real-time measurement of high sound pressure sound fields, achieved major technical indicators, completed the research and development of instrument core technologies and development of instrument prototypes; The investigation showed that the system was stable; the expected high sound pressure scientific experiment results were obtained, and the application of relevant biomedical sciences under strong sound pressure conditions was explored, which is expected to create a new direction for research in sonochemistry, materials science and physics. The project revolved around the research and development of a spherical collection system and obtained a number of original research results. It published 114 SCI academic papers and obtained 48 authorized invention patents, including 29 Chinese invention patents and 19 international invention patents; participated in the formulation or revision of international, There are 5 national, industry, and local standards. The expert group believes that the project has completed the research content, achieved the expected goal, and agreed to pass the acceptance of the project.

The conclusion acceptance expert group leader and academician Wang Weiqi of Fudan University pointed out that the major instrument development project has obvious original innovation characteristics, and it is very difficult to complete the research content. The project team has overcome difficulties and successfully completed the five-year joint research. Scheduled Tasks. He hoped that the team of the project team could continue to unite and cooperate after the conclusion of the project and increase the openness and sharing of scientific research at home and abroad based on the spherical focus sound collecting scientific instrument system, making it an open research platform for high sound pressure research as soon as possible; Further improve the 109 Pa-level high sound pressure test technology system and test standards; carry out scientific research in the fields of biomedicine, physics, materials and chemistry based on the spherical focus sound collecting scientific instrument system, and further reveal new phenomena under high sound pressure conditions And its mechanism.

Relevant leaders of the Planning Bureau and Finance Bureau and relevant personnel of the Medical Science Department attended the meeting.

Fabric Cleaner

Fabric cleaner is a type of cleaning product that is specifically designed to clean and remove stains from various types of fabrics. It is typically used on upholstery, carpets, and clothing. Fabric cleaners can come in various forms such as sprays, foams, and liquids. They contain special ingredients that help to break down and remove dirt, grime, and stains from fabrics without damaging them. Some fabric cleaners may also contain disinfectants or deodorizers to help eliminate odors and kill bacteria. It is important to read the label and follow the instructions carefully when using fabric cleaner to avoid damaging the fabric or causing any adverse reactions.

The carpet shampoo is used to clean the carpet, remove dust, oil and other pollutants on the carpet, restore the original color and feel of the carpet, and leave elegant fragrance. It can also be used to clean soft surface materials such as sofas, curtains, chair covers and indoor decorations.

Fabric sofa cleaner is a liquid cleaning product used to wash cloth products or clothes or clean furniture and other things. It uses a variety of new surfactants, with strong detergency, easy rinsing, no irritation to the skin, no corrosive ingredients, and can completely remove stubborn dirt without damaging the fabric.
