查询词典 proton

The photocatalytic processes and the production of intermediates and by-products are examined by means of UV-vis spectra, proton-NMR profile, trapping ESR technique, GS-MS, Ion Chromatography,ξ-potential measurements, peroxide measurements and chemical oxygen demand measurements, etc. Some surprising fruitions are acquired for the first time.

借助紫外可见波谱、核磁、自旋捕捉ESR、色质联用、离子色谱、ξ-电位仪、过氧化物以及化学需氧量的测量等技术，对光催化过程及中间产物和付产物的生成进行了检测，获得了一些显著的成果。

Another important issue associated with these processes is their close relation to the off-diagonal gluon distribution of the proton.

另一方面，这些过程对off-diagonal的胶子分布函数很敏感。

It is shown that either the deep Compton or the double photon production processes can be used to probe the structure of photon and proton, as well as to test the mechanism of quark and gluon fragmentation to photon.

我们证明了，在HERA条件下，无论是深度Compton过程，还是双光子产生过程都能够用于研究光子、质子的结构函数，以及研究夸克或胶子的光子碎裂机制。

We shall see later that gluons are essential to the dynamics of the quarks inside the proton.

后面将会看到，胶子对于质子内夸克的动力学机制来说是必需的。

In simplest terms, the proton comprises three quarks with gluons zipping between them to convey the strong force.

简单来说，质子由三个夸克和拉紧它们的胶子组成来传送强力。

In simplest terms, the proton comprises three quarks with gluons zipping between them to convey the strong force.

最简单地说，质子含有三个夸克和胶子，胶子快速穿梭于夸克间来输送强力。

Thanks to the uncertainties of quantum mechanics, however, myriad gluons and quark-antiquark pairs flit into and out of existence within a proton in a frenzy that's nearly impossible to analyze but that produces 95% of the particle's mass.

但是，由于量子力学的不确定性，在一个质子中无数胶子和夸克-反夸克对极速的流入和流出，这几乎是不可能分析的，但这些产生了粒子95％的质量。

Starting from a theoretical description of its innards, physicists precisely calculated the mass of the proton and other particles made of quarks and gluons.

从理论描述内部结构开始，物理学家精确计算出了质子和其他由夸克和胶子形成的微粒的质量。

Starting from a theoretical description of its innards, physicists precisely calculated the mass of the proton and other particles made of quarks and gluons.

物理学家从对质子内部结构的一个理论描述出发，精确计算出了质子和其它一些由夸克和胶子构成的粒子的质量。

Thanks to the uncertainties of quantum mechanics, however, myriad gluons and quark-antiquark pairs flit into and out of existence within a proton in a frenzy that's nearly impossible to analyze but that produces 95% of the particle's mass.

但是，由于量子力学的不确定性，无数胶子和夸克-反夸克组合在质子内部不停地出现又消失，这种狂乱状态几乎不可能分析，但是这种状态生成了粒子95%的质量。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
