质子

The 400nm femtosecond laser photoionization and dissociation of pyridine-(water 〓 cluster was studied.

在吡啶-水团簇的质谱中同样看到了在纳秒激光下看不到的非质子化产物〓。

Moreover, the process of magnetic loop formation due to the foot point twist in the photosphere is reproduced by three-dimensional MHD numerical simulation.

考察了磁场重联时质子和电子的加速过程和轨道特征，提出拾起过程是一种有效的加速机制。

In an electrolytic cell with proton exchange membrane as the diaphragm, it was found from the electrooxidation of 3-picoline at a PbO2 electrode in acetone/water mixed solvents that the current density at the same anode potential not only increases remarkably, but also the selectivity and the current efficiency of electrooxidation from 3\|picoline to nicotinic acid increase obviously compared with the pure water as the solvent.

在以质子交换膜为隔膜的电解槽内，通过3-甲基吡啶在PbO2电极上的电氧化研究，发现在丙酮-水混合溶剂中，与纯水作溶剂相比，不仅在相同阳极电位下电流密度大幅度上升， 3-甲基吡啶电氧化生成烟酸的选择性和电流效率也明显提高。

When a proton moves to a new point, a unit charge has been increased at the new point.

当一个质子从上一点移动到下一点时，下一空间点上就增加了一个单位电荷，根据现有的电动力学理论判断，会发生势的推迟。

The other kind of electricity is positive electricity. Its ultimate particles are called protons.

另一种类型的微粒带正电，我们把这种终极微粒称为质子。

It is in electricity can one kind form,including negative electricity and positive electricity two kinds, made up of electron and proton they respectively, may be made up of the electron and positive electron too, usually with the static unit such as the static Coulomb(C or the tolerance of electromagnetic unit such as Coulomb(C , from the frictional electricity thing

电是能的一种形式，包括负电和正电两类，它们分别由电子和质子组成，也可能由电子和正电子组成，通常以静电单位或电磁单位度量，从摩擦生电物体的吸引和排斥上可以观察到它的存在，在一定自然现象中也能观察到它，通常以电流的形式得到利用。

Once the number of the positive proton and electron doesn't equalize, the particle will become positive ion.

当其中的质子与电子的数量不成等比，无法对等时，那麼粒子就会转化为正离子。

For instance, the antimatter opposite of an electron, known as a positron, is positively charged.

例如，电子的反物质就是带正电的质子。

The characterization of planar waveguides fabricated in X-cut LiNbO_3 by proton exchange and the post annealing is studied.

质子交换技术是制作高折射率、低损耗、具有偏振特征的LiNbO3光波导器件的非常成熟的方法[1]。

It is my great honor and pleasure to accept a professorship to be of any help for the proton therapy at Wanjie.

我非常荣幸和高兴能够受聘为教授，为万杰的质子治疗提供一些帮助。

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％。
