Ab stra ct:Ai m.To our know ledge,there is no pape r in the open literature dealingw ith the top ic of the above title.

I n Ref.3,we discussed the m ethods of measuring m ateria l da mp ing.Starting fr om Ref.3,we now design,build and operate a m ate rial da mp ingm easuring system f or use in high2te mperature and vacuum envir onm ent.Sec tion1of the full paper deals with designing and building a setup f or i mp le m enting high2te mperatur e and vacuum envir on2 ment;Fig.2gives the sche m atic of the setup’s constr uc tion.Section2deals with designing the ma terial da mp ing measuring syste m f or use in high2temperature and vacuum envir onment.The m easuring syste m consists of five sub2 syste m s:heating oven and heating c ontr ol,vacuu m contr ol,temper a tur e monit oring,wate r cooling,and da mp ing measuring.Section3presents the operati on results in Figs.6thr ough8;their analysis shows p r eli m inarily that: (1)the te mpe r ature of the measuring syste m can be automa tically contr olled in the range of r oom te mperatur e to 1100℃;(2)the pressure of r a r efied a ir can be reduced to as low as011Pa;(3)its te mpe r a ture and vacuum can be kept stable.Its ope r a tion is easy and si mple.
