您要查找的是不是:
- electron pair bond(e.p.b.) [化] 电子对键
- electron pair bond 共价键,电子对键
- Another is the Lewis definition (also 1923): An acid (see electrophile) is a chemical that can accept an electron pair from a base (see nucleophile), which they share to form a covalent bond. 另一种理论是路易斯(Lewis)理论(也是在1923年发表):酸(参阅electrophile)就是能由碱(参阅nucleophile)接受一个电子(electron)对形成一个共价键(covalent bond)的化学物质。
- The number of electron pairs an atom can share with other atoms. 共用电子对数,共价一个原子与其他原子共用的电子的对数
- This paper analyzes shell electron pair repulsion theory, valence-bond theory and molecular orbital theory on molecular structure of noble gas compounds. 对稀有气体化合物的分子结构分别用“价层电子对互斥理论”、价键理论”和“分子轨道理论”进行了分析处理。
- An axial electron pair meets at right angles with 3 neighboring pairs. 轴向电子对与三个相邻的电子对相交成直角。
- An electron pair. 电子偶电子对
- He believes that the release of the so-called "pair bonding" hormone oxytocin might explain the calming effect. 他认为所谓的配偶融合荷尔蒙催产素的释放或许能够解释这种缓解效应。
- By calculating the number of va-lence electron shell,we can gain the geometry array of the electronic pair,and then judge the molecular structures. 计算出价层电子对数,得到电子对的几何排布,从而判断出分子的几何构型。
- I bought a pair of tan leather shoes the other day. 前几天我买了双棕褐色的皮鞋。
- l electron pair repulsion theory 价层电子对互斥理论
- And women, as it turns out, are more prone to the "crush high" than men.Blame it on the neuropeptide oxytocin, sometimes known as the "cuddle hormone" because of its influence on pair bonding. 研究发现,女性比男性更容易“意乱神迷”,这是由于神经肽催产素(由于它对配偶联系产生的影响,有时也称作“拥抱荷尔蒙”)的缘故。
- In this model the arrangement of bonds around the cetral atom is considered to depend upon how many valence-shell electron pairs. 在这个模型中,认为围绕中心原子的化学键的排列取决于价层中电子对的数量。
