质子

We thought of a nucleus as make up of neutron and proton.

我们认为原子核是由中子和质子构成的。

The NIEL induced by low energy proton in Si and GaAs have been calculated using analytical method and Monte-Carlo code. Thin_target approximation was used when calculating NIEL by SRIM code and the result compared with that of other authors'. The results show that thin_target approximation is reasonable and NIEL scaling is feasible. The NIEL values become lower after taking into account the screening effect.

In the condensation process, a phase transfer catalyst is added, the mother liquor is recycled, proton polarity solvent crystallization is used to improve the purity of nitryl coumpounds, and the yield is above 98.0%.

缩合反应中加入相转移催化剂，母液循环使用，并采用质子极性溶剂重结晶，提高了硝基化合物的纯度，收率达到98.0％以上。

In a normal atom, the number of protons is equal to the number of electrons present .

在一个正常的原子中，质子数等于存在的电子数。

The development of new experiments for neutron halo is briefly described, while the isospin and energy dependence of Glauber theory and its importance in describing halo nuclei -nucleus scattering are discussed.

简要介绍了中子晕和质子晕研究的最新实验进展，同时，讨论了近年来发展的同位旋，能量有关的具有晕核结构的 Glauber理论及它在描述晕核与核散射时的重要性。

The_n and_ are the neutron proton ratio of the nucleon emission and that of the fragment emission respectively.

这里 n 和 frag分别是核子发射和碎片发射多重性的中子质子比。

There is more than one proton in the nucleus.

有超过一个以上的质子在核子里。

At some point the stability of the orbital electrons in the ordinary sense must be destroyed as more protons are added to the nucleus.

某些电子轨道稳定性的要点在一般判断必需要破坏如大多质子增加到原子核之中。

In the PEMFC system, the oscillogram of the current is stable while the current is 1A; however, when the current is changed into 2.1A (subject to the power is 230W), the current output fluctuates and twists. After comparing the result generated from the simulation test of PSIM and experiment with the real data, this theory of the dissertation is proved to be workable.

本论文之研制之质子交换膜燃料电池电能转换系统，当电流为1A与1.9A时，电流波形图相当稳定，而当电流改变成2.1A时，此时功率约为230W，其输出电流波形及产生扭曲变形较不稳定，经由PSIM软体模拟与实验比较得出稳定燃料电池发电系统，并且与实际量测结果互相比较，以验证本文研究系统之可行性。

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％。
