质子

Atomic nuclei consist of combinations of protons, or positively-charged particles, and neutrons, or uncharged particles.

原子核是由质子与种子相结合而构成；之子也叫带正电荷的粒子，中子也叫不带电荷的粒子。

Since the neutron is uncharged, it is not affected by the charged electrons and protons of the target atom, and is therefore more likely to be captured than any other particle, provided that it is in resonance with an energy level of the nucleus.

由于中子不带电荷，所以不受带电粒子和靶原子的质子的影响。而且，如果中子同核的能级协调一致，就会更易于被其他任何粒子俘获。

An acid/base indicator is a weak organic acid or a weak organic base whose undissociated from differs in color form its conjugate base or its conjugate acid form.

酸碱指示剂一般是弱的有机酸或有机碱，其中酸式及其共轭碱式具有不同的颜色，当滴定至等当点时，过量的酸或碱使指示剂得到或失去质子，由碱式变为酸式，引起颜色的变化。

And yet no one would suggest that an unobserved proton is an abstract entity.

但是没有人会建议说，不可观察的质子是抽象实体。

Since the side chains on the polymers bear nitrogen atoms with an unshared electron pair, the polymers become protonated in acidic solution to generate polycationic species.

由于侧链对聚合物承担氮原子与一取消共用电子对，聚合物成为质子在酸性溶液中产生polycationic物种。

The chemical shifts of the carbon atoms connected with the nitrogen atoms in the protonated pyridines were moved upfield in comparison with those of the pyridines.

在质子化的吡啶中，与氮原子相连的碳原子的化学位移与吡啶相比移向高场。

A dye recycled photosensitization system has been designed. As a result of studies in the mechanism of electron transfer reaction of xanthene iodonium salt, it is proposed that the dye-recycled process consists of three-step reactions during the photosensitization: The oxidative fading product of dye is formed through electron transfer under irradiation; In the presence of H-donor, product changes into acidic leuco dye product; Product undergoes deprotonization under action of base to regenerate initial dye.

本文设计了染料循环再生的光敏反应体系，通过对占吨碘翁盐电子反应机制的深入研究，提出了占吨染料在光敏反应过程中的染料再生循环，它依次由三个反应过程组成：在光作用下，通过电子转移反应，产生染料氧化褪色体；在H给体存在下，通过H转移反应，使产物转化为染料酸式隐色体；在碱作用下，发生去质子反应，染料再生回复到染料的起始结构。

By diffusion of heavy metal ion into zinc oxide crystal,ACR-1 white antistatic thermal control coating is developed with acrylic resin.The space environment effects on the solar absorbtance of the coating and comparison with silicon white thermal control coating are investigated.

通过在氧化锌晶格中掺入重金属离子，得到具有防静电功能的白色颜料，再以丙烯酸树脂为粘合剂制备出空间飞行器外表面用的 ACR-1防静电白色热控涂层；研究了空间环境效应(包括紫外辐照，电子和质子辐照)对该热控涂层太阳吸收率的影响并与有机硅白色热控涂层进行了比较。

The acidimetric supernatant was considered as the system blank to compensate the influence of particle dissolution and complex reactions between soluble components on estimation of proton consumption.

将酸量滴定上清液作为体系空白以补偿固体颗粒溶解和组份间络合反应对定量估算质子消耗的影响。

Results The consumption sum of the drugs for antiacid and peptic ulcer diseases increased year by year,whose average annual incremental rate was faster than that of the west medicine,i.e.25.77%and 12.02%...

结果该院抗酸药及治疗消化性溃疡病药的销售金额逐年增长，其增长率较西药总体增长率高，平均年增长率分别为25.77%和12.02%；质子泵抑制剂和胃黏膜保护剂的销售金额排序各年均位于抗酸药及治疗消化性溃疡病药的前2位；磷酸铝凝胶在3年中均占据用药金额的首位，奥美拉唑的用药频度增长显著，平均年增长率为43.8%。

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％。
