维普论文检测系统检测前原文:
振幅。由于振动一周所消耗的总能量与其最大振幅A0的平方成正比,并且ΔW正比于2A0ΔA0,所以"∆W" /"W" "=" ("2∆" "A" _"0" )/"A" _"0" 。当δ很小时,则有 "δ=" "ln" 〖"A" _"n" 〗 "-" "ln" 〖"A" _"n+1" 〗 "=" ("A" _"n" "-" "A" _"n+1" )/"A" _"n" "=" "1" /"2" "∆W" /"W" "=" ("∆" "A" _"0" )/"A" _"0" "≈" "ln" 〖"A" _"0" /"A" _"1" 〗 (1-12) 与式(1-7)相比较,可得: "Q" ^"-1" "=" "1" ...
