质子的

Although all nuclei of a given element contain the same number of protons, they may have different numbers of neutrons.

虽然，给定元素的所有原子核都含有相同数目的质子，但它们的中子数可以不同。

Suitably inspired by such thoughts, in the 1960s Chinese physicists invented a sort ofonion-layer theory of particles called the straton model, in which both protons andelectrons have a common constituent.

受这个思想指导，在六十年代中国物理学家们发明了一种洋葱式的粒子理论，称为层子模型（火车注：估计大家上中学的时候都学过），其中质子和电子具有共同的组成成分。

Fluorescence spectra, absorption spectra and protonation properties of Chinese herbal medicine—Cortex Fraxini and its effective components—aesculin and aesculetin have been studied in this thesis. Based on the spectroscopic properties of aesculin and aesculetin at different pH values of their water solutions, a fluorescence method for the determination of aesculin and aesculetin in Cortex Fraxini was developed.

本文详细研究了中药秦皮及其有效成分秦皮甲素和秦皮乙素的荧光光谱与吸收光谱，深入探讨了秦皮甲素和秦皮乙素的光谱性质和质子化作用，制定了秦皮药材中秦皮甲素和秦皮乙素的荧光分析方法。

Similarly the positively charged proton has a negatively charged antiparticle, the antiproton.

同样的，带正电荷的质子具有其带负电荷的反粒子—即反质子。

A stable, positively charged subatomic particle in the baryon family having a mass1, 836 times that of the electron.

质子重子族群中一种稳定的带正电的中子核，质量为电子的1，836倍

Only about 5% of our universe is made of normal matter as we know it, consisting of protons and neutrons, or baryons, which along with electrons, form the building blocks of ordinary matter.

我们知道我们的宇宙只有约5%是由质子和中子以及电子这些普通物质构成，剩下的由难以捉摸的暗物质（23%）和暗能量（72%）组成。

Such cases as hydride ion transfer from reduced nicotinamide coenzymes or the carbanion generated by base abstraction of a substrate proton may lead to attack at the flavinN-5 positions; some nucleophiles, such as the hydrogen peroxide anion, are added on the C-4a position with its frontier orbital.

从减少烟酰胺辅酶或基片基抽象所产生的质子氢离子负离子转移这种情况可能会导致攻击的flavinN - 5的位置；例如过氧化氢负离子一些亲，被添加在C - 4A条位置其前线轨道

The research of catalysts is important to reduce the cost of PEMFC.

催化剂的研究对于降低质子交换膜燃料电池的成本，促进其商业化有极其重要的意义。

Although the LHC isn't the first collider ever to be built, it attains the highest energy.

尽管这个大型粒子加速器不是建造得最大的对撞机，但它可以使对撞的质子获得最高的能量。

An Energy Amplifier, which is composed of three cyclotrons, is one type of ADS. It will be used to produce 14.4 MW proton beam (12 mA, 1.2 GeV) and to operate a 1500 MW nuclear reactor.

能量放大器是一个基于回旋加速器组合的ADS方案，由三级回旋加速器组成约加速器系统可以产生流强为12mA和能量为1.2GeV的质子束（束流功率14.4MW），用以驱动1500MW的核反应堆。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
