Method for the sensitometry of industrial x - ray films for energies up to 3 million electron volts 能量达3百万电子伏工业用x射线胶片感光度的测定方法
Ionizing an atom of hydrogen takes an energy of 13 . 6 electron volts , an amount delivered by a photon of ultraviolet light 游离氢原子需要13 . 6电子伏特,相当于一个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实验中,激光等离子体产生的x光主要分布在亚仟电子伏特区( 0 . 1 - 1 . 5kev ) ,它的总能量、能谱特征、发射时间过程和空间分布都是理论和实验极为关心的基本数据。
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,弦论无法以实验来检验,因为弦论所涉及的能量太高,物理学家在实验室中造不出那麽高的能量,但是巩讷指出非可换几何所做的预测,譬如希格斯质量( 1600亿电子伏特) ,却是可以检验的,他说甚至重整化也可以证实。
英文解释
a unit of energy equal to the work done by an electron accelerated through a potential difference of 1 volt 同义词:eV,
