intensity n. 1.(思想、感情的)強烈,激烈。 2.強度。 3.【攝影】(底片的)明暗度。 go mad at the intensity of one's grief 因為過度悲傷而發(fā)瘋。 intensity of illumination 照度,光照強度。 bombardment intensity 炮火強度。 current intensity電流強度。 labour intensity 勞動強度。 luminous intensity 光度。 radiant intensity【物理學(xué)】輻射強度。
spectrum n. (pl. -tra ) 1.【物理學(xué)】譜,光譜;波譜;能譜,質(zhì)譜。 2.【無線電】射頻頻譜;無線電(信號)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 太陽光譜。 a wide spectrum of opinion 意見的不同幅度甚大。
But in the case of fixed target the spectra intensity become weak with the target long exposed to the laser radiation 反之使激光照射于固定靶上的固定點, libs信號的強度逐漸下降,從而影響譜線強度的穩(wěn)定性。
( 2 ) the effect of rotary target and fixed one on libs " intensity is studied . it is shown that the spectra intensity is stable when the rotary target is used ( 2 )研究了靶點的性質(zhì)對libs信號強度的影響,實驗結(jié)果表明,在測量過程中若每個脈沖激光照射在固體靶上的不同點,譜線強度具有很高的穩(wěn)定性。
( 2 ) according to lambert - beer law and related optical signal processing technology , analysis formula is presented to express the relationship between spectrum intensity and gas density after the two widely used semiconductor light resource led and dfbld functioned with inferred absorption spectrum line ( 2 )依據(jù)朗伯比爾( lambert - beer )定律和光學(xué)信息處理技術(shù),給出了兩種常用半導(dǎo)體光源led和dfbld與紅外吸收線作用后,光譜分量強度與氣體濃度關(guān)系的解析表達(dá)式。
