查询词典 electrons

When voltage is applied and there is a path for the current, electrons move from the negative terminal along the path to the positive terminal.

若施加电压且有路径给电流，电子就会从负极沿著路径移向正极。负极排斥电子，而正极吸引电子。

Methane, oxygen and H_2O molecules are activated, ionized and dissociated into active particles such as CH_3~+, O~-, H_2O~+, CH_3, CH_2, CH, H,OH and O, by nonelastic collision with high energy electrons. The particles react with each other in the reactor to synthesize chemically products including gaseous oxy-hydrocarbons.We study the rule of reaction by changing electrical parameter, gas flow etc. Study the conversion of methane, selectivity of gaseous hydrocarbons and yield of methanol under different reaction condition.

针对常规甲烷催化转化和氧化偶联制备含氧化合物的问题，遵循国际化学科学研究前沿"绿色化学"原则，采用自然界存在丰富的CH_4、H_2O和O_2为原料，在绿色友好的常温大气压无任何催化剂的条件下，采用强电场电离放电加速电子及其激励气体分子的极端物理手段，在反应腔体内进行无任何环境污染的非平衡等离子体化学反应，将气体分子激发、电离、离解成CH_4~+、CH_3~+、CH_4~·、H_2O~+、H_2O~·、O_2~+、O(~1D)等活性粒子，生成气态烃及含氧碳氢化合物，整个反应过程实现零污染、零副产品。

次氯酸钠的不稳定性是由于次氯酸根离子价层电子对空间构型的高度不对称性和次氯酸根离子中阳离子C l+的高离子势所决定的。

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。

A body is negatively charged when it has electrons in excess of its normal number.

当物体所带的电子超过正常数时，该物体便带电。

Matter is composed of molecules, which are composedof atoms, which are composed of atomic nuclei and electrons.

物质是由分子组成的，分子是由原子组成的，原子是由原子核和电子组成的。

Matter is composed of molecules, which are composed of atoms, which are composed of atomic nuclei and electrons.

物质是由分子组成的，分子是由原子组成的，原子是由原子核和电子组成的。

The positive charges here is the nucleon with the neutrons and then we have electrons in a cloud around it.

在这里正电荷表示核子与中子，然后我们有一团云状的电子围绕著它。

Energy loss due to collision between electrons and ions never exceeds 20% of ohmic power.

在HT—7装置上，电子、离子碰撞而转移给离子的能量只占欧姆功率的百分之十几。

The results show that the sturcture of each of Tin clusters is obtained by capping one Ti atom to the Tin-1. The Natural bond orbital analysis show that the 4s , 4p, 4d orbitals hybridizes with 3d orbital, and about one electron transfer from 4s orbital to 3d orbital. Moreover, the electrons also transfer between different atom. The results also indicate that the average bond length of clusters were determined by the 4d and 3d orbitals except Ti7. But for Ti7, the average bond length only depend on 3d orbital.

研究结果表明： Tin(n=2~7)团簇都依带帽的形式在前一个团簇的结构基础上加一个原子变化而来；通过自然轨道分析发现，团簇原子的轨道存在sp-d杂化，有大约一个电子从4s转移到了3d，原子之间亦存在电子转移，而且除Ti7外，团簇键长由最外层4d轨道电子和3d轨道共同决定，在Ti7中，团簇键长由3d轨道决定。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。
