Method for the sensitometry of industrial x - ray films for energies up to 3 million electron volts 能量達3百萬電子伏工業(yè)用x射線膠片感光度的測定方法
Ionizing an atom of hydrogen takes an energy of 13 . 6 electron volts , an amount delivered by a photon of ultraviolet light 游離氫原子需要13 . 6電子伏特,相當于一個紫外光光子所能提供的能量。
In icf ecperiment , the x ray produced by laser plamsa mainly distributes in sub - kilo electron volt region , whose overall energy , energy - spectrum characteristic , projecting time and its distribution in space are basic dataes in theory and experiment 在icf實驗中,激光等離子體產(chǎn)生的x光主要分布在亞仟電子伏特區(qū)( 0 . 1 - 1 . 5kev ) ,它的總能量、能譜特征、發(fā)射時間過程和空間分布都是理論和實驗極為關(guān)心的基本數(shù)據(jù)。
Whereas string theory cannot be tested directly ? it deals with energies that cannot be created in the laboratory ? connes points out that noncommutative geometry makes testable predictions , such as the higgs mass ( 160 billion electron volts ) , and he argues that even renormalization can be verified 例如,弦論無法以實驗來檢驗,因為弦論所涉及的能量太高,物理學(xué)家在實驗室中造不出那麼高的能量,但是鞏訥指出非可換幾何所做的預(yù)測,譬如希格斯質(zhì)量( 1600億電子伏特) ,卻是可以檢驗的,他說甚至重整化也可以證實。
英文解釋
a unit of energy equal to the work done by an electron accelerated through a potential difference of 1 volt 同義詞:eV,
