spectrum n. (pl. -tra ) 1.【物理學(xué)】譜,光譜;波譜;能譜,質(zhì)譜。 2.【無(wú)線電】射頻頻譜;無(wú)線電(信號(hào))頻譜。 3.【心理學(xué)】(眼睛的)余像;殘像。 4.〔轉(zhuǎn)義〕范圍,幅度;(連續(xù)的)系列。 an absorption spectrum 吸收(光)譜。 a bright line spectrum 線狀光譜。 an optical spectrum 光譜。 a solar spectrum 太陽(yáng)光譜。 a wide spectrum of opinion 意見的不同幅度甚大。
Although the data record contains all the essential information about the desired source spectrum , that information is folded together with details of the instrument response 并且這套譜儀適用的能譜范圍廣( 0 . 1 ? 10kev ) ,敏感度高,有記錄大量信息的能力。
The experiment results have proved that the measure system is of high accuracy . the research on pulse light source spectrum measurement has reached the anticipated demands 經(jīng)過(guò)實(shí)際使用,本系統(tǒng)取得了滿意的結(jié)果,能夠滿足脈沖光源生產(chǎn)單位的測(cè)試要求,達(dá)到了研究的預(yù)期目的。
