protonation

If the incident proton collides with a proton bound in a nucleus, the threshold energy is lower because the target proton is bound . 如果入射質子是與束縛在原子核內的質子相碰撞,那么閾能會低一些,因為作為靶的質子是束縛著的。

Since fulvenes show no evidence of ring currents, the chemical shifts of the protons will be found in the normal definite region . 既然富烯不顯示環電流存在的跡象,所以質子的化學位移仍然發生在正常的鏈烯區。

The atomic number represents the number of nuclear protons or, in the undisturbed state, the number of extranuclear electrons . 原子序數表示原子核內質子的數目,也是在未被干擾的狀態下核外的電子數。

The net charge of a body might be described by a statement of the excess number of electrons or protons in the body . 一個物體所帶凈電荷的量,可以用在這個物體內的過剩電子數或過剩質子數來表示。

Note the e stands for two different things in (6. 76) and (6. 77): the base of natural logs, and the proton charge . 注意(676)和(677)中的e分別代表兩種不同的意思:自然對數底和質子電荷。

Standard theory predicts that two neutrinos are produced for every fusion of four protons into a helium nucleus . 標準理論預言,在由四個質子變成一個氦核的每一次聚變過程中要產生兩個中微子。

From time to time, scientists have speculated that the proton and electron charges might not be exactly equal in magnitude . 屢次地,科學家們推究質子與電子的電荷大小可能不恰好相等。

The energy equipartition time is longer than the interparticle collision time by the mass ratio of proton and electron . 由于質子與電子的質量比很大,能量平衡時間比粒子間碰撞時間長。

At the briefest glance at a table of elementary particles, we can see straight away that the neutron and proton are very similar . 查閱基本粒子表,立刻就可看出,中子和質子非常相似。

For example, we know that within a certain time period neutrons decay into protons and some other particles . 試舉一例:我們知道,中子在一定的時間里會衰變成質子和某些其他粒子。

This conclusion is consistent with the idea that all atomic nuclear are built wholly of neutrons and protons . 這個結論與如下的思想是一致的:所有的原子核全部由中子和質子組成。

When the total number of protons equals the total number of electrons, the body as a whole is electrically neutral . 當質子總數等于電子的總數時,這個物體就整體來說是電中性的。

Heavier nucleus was believed to be formed of a number of protons and electrons packed closely together . 人們相信,較重的原子核是由若干個質子和電子緊密聚集在一起而形成的。

A rudimentary description of a nucleus consists in specifying the number of protons and neutrons it contains . 對某個原子核的初步描述,在于確定它所含的質子和中子的數目。

The incoming streams of solar protons and electrons are affected by the earths magnetic field in a complicated way . 太陽的質子和電子的入射流,受到地球磁場的復雜作用。

When the protons strike the air, nuclear collisions occur, giving rise to a shower of various particles . 當質子撞擊空氣時,發生原子核碰撞,產生各種各樣的粒子的簇射。

Two protons brought together will also fly apart-if neutrons are not present to hold them together . 兩個靠攏的質子也會飛開--如果不是有中子把它們保持在一起的話。

The gravitational interaction is disregarded when interactions between individual protons are considered . 在考慮單個質子間相互作用時,萬有引力可以忽略不計。

We shall see later that gluons are essential to the dynamics of the quarks inside the proton . 后面將會看到,膠子對于質子內夸克的動力學機制來說是必需的。
