质子

Today, besides the electrons, protons and neutrons, many more particles have been discovered .

今天除了电子、质子和中子外，还发现了更多的粒子。

Even protons and neutrons do not exist, for those things contain quarks as parts.

甚至质子和中子也是不存在的，因为这些东西包含夸克作为其部分。

The nucleus of an atom is the small core of protons and neutrons.

原子的核是由质子和中子组成的小核心。

With the same number of protons, all nuclei of a given element may have different numbers of neutrons.

译：虽然某个元素的所有原子核都含有相同数目的质子，但它们含有的中子数可以不同。

With positively charged protons and neutrons without charge of the nucleus.

带正电荷的质子和不带电荷的中子组成原子核。

They have the same number of protons in their nuclei (this is the defining characteristic of an element), but different numbers of neutrons.

在它们的原子核中质子数是相同的（这是一个元素定义性的特征），但是中子的数量不同。

Atoms are made from a nucleus of protons and neutrons and a cloud of electrons.

原子是由质子和中子组成的原子核与围绕原子核的电子云构成的。

Although all nuclei of a given element contain the same number of protons, they may have different numbers of neutrons.

虽然，给定元素的所有原子核都含有相同数目的质子，但它们的中子数可以不同。

Suitably inspired by such thoughts, in the 1960s Chinese physicists invented a sort ofonion-layer theory of particles called the straton model, in which both protons andelectrons have a common constituent.

受这个思想指导，在六十年代中国物理学家们发明了一种洋葱式的粒子理论，称为层子模型（火车注：估计大家上中学的时候都学过），其中质子和电子具有共同的组成成分。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
