质子的

Due to different influences of various factors, each of these protons show different motion characteristics.

不同位置的质子，因主要影响因素的不同，表现出各自特殊的运动特征。

Matter is usually electrically neutral,that is,it has as many protons

物质一般为不带电的，就是说，它的质子和电子数量是相等的。

We use statistical method and assume that the proton in a series different Fock state that every Fock state has definite number of partons .

研究的方法是用系综统计的方法，认为质子是处在一系列的Fock态上。

By examining the type and momentum of the displaced nucleons, the authors determined that most of the pairs were mixed neutron-proton pairs.

通过检测分离出的核子的类型和动量，笔者得出结论：绝大部分的核子对是由中子和质子混合组成。

Fermilab has added the two-mile Main Injector accelerator to increase the number of proton-antiproton collisions in the Tevatron, greatly enhancing the chances for important discoveries in Run II.

费米实验室增加了两英里长的主要喷油加速器增加质子反质子碰撞的Tevatron ，大大增强了机会，重要的发现在运行二。

The elements K, Ca, Fe, Cu, Zn, Se and Rb in erythrocyte of 78 cases with different thyroid hormone status have been measured by PIXE and INAA .

用质子激发X荧光和中子活化分析方法测量了不同甲状腺激素水平的甲状腺病人红细胞中的微量元素K、Ca、Fe、Cu、Zn、Se和Rb等的含量。

Abstract?The elements K, Ca, Fe, Cu, Zn, Se and Rb in erythrocyte of 78 cases with different thyroid hormone status have been measured by PIXE and INAA.

用质子激发X荧光和中子活化分析方法测量了不同甲状腺激素水平的甲状腺病人红细胞中的微量元素K、Ca、Fe、Cu、Zn、Se和Rb等的含量。

It is a long-baseline experiment: the beam from the Main injector, Fermilab's high-intensity source of protons feeding the Tevatron accelerator, can be sent from Batavia 735km away to the Soudan mine in Minnesota.

这是一个漫长的基准实验：梁从主喷嘴，费米实验室的高强度来源喂养Tevatron质子加速器，可以发送从巴达维亚七百三十五公里以外的苏丹排雷在明尼苏达州。

Results The mean dose to 90% of the cochlea was reduced from 39% of the prescribed posterior fossa boost dose to 1.6%,and the 90% mandibular joint volume was 26.1% and 0.4% for the Xrays and proton respectively.Mean dose to the 50% heart volume was reduced from 63.3% to 0.8%,and 90% thyroid volume was 72.2% and 0.5% for the Xray and proton respectively.

结果 X线与质子适形放射治疗计划相比，右侧耳蜗90%的体积平均受照剂量分别为后颅窝加量野的39%和1.6%，右颞颌关节90%体积平均受量分别为26.1%和0.4%， 50%心脏平均受照剂量分别为脊髓野处方剂量的63.3%和0.8%，90%甲状腺平均受量分别为72.2%和0.5%。

Chiral amine-protonic acids are highly efficient and excellent enantioselective organocatalysts developed in recent years. They have been successfully applied to a number of enantioselective organic reactions, such as asymmetric aldol condenstion, Michael addition, Diels-Alder cycloaddition, Strecker reaction and so on.

手性胺-质子酸是近年来发展起来的新型高效、高对映选择性的有机催化体系，已成功应用于催化不对称Aldol反应、Michael加成反应、Diels-Alder反应和Strecker反应等许多重要的有机合成反应。

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％。
