On 28 Feb 2013，the technical acceptance meeting of ion beam polishing equipment，which is sponsored by The National Natural Science Funds (NSFC) was held in NIAOT.

Leaders and experts invited from NSFC、Nanjing University of Science and Technology (NJUST)、National Astronomical Observatories (NAO) etc attended the meeting.

Prof.Guo weiyuan (project leader) reported the executive condition of the project.

Prof.Cheng lei（leader of the test expert group for the project acceptance meeting）reported the on-site test results.

The whole expert group carefully examined the contents of the project and inspected on-site the equipment，which is the biggest one in China with accuracy of λ/100 during polishing.

All the experts agreed that experimental results and relative technical data of project reach requirement of NSFC.

Prof. Yongtian Zhu(Director of NIAOT) representing the NIAOT, appreciated the experts’ confirmation of project achievements, and substantial support from NSFC.

Prof. Zhu also expressed that we still should carry out further engineering study based on these achievements, and prepare well for the actual application.
