查询词典 affinity

Koopmans theorem is an approximation in molecular orbital theory , such as density functional theory , or Hartree-Fock theory, in which the first ionization energy of a molecule is equal to the energy of the highest occupied molecular orbital, and the electron affinity is the negative of the energy of the lowest unoccupied, i.e.

如同密度泛函理论或者Hartree－Fock理论，分子轨道理论中常用到的Koopmans 定理也是一种近似。

The activities of carboxylesterase、glutathion-S-transferase and acetylcholinesterase per insect increase greatly and the properities of esterase and acetylcholinesterase change also throughout larval development from 1-day-old to 4th instar. The affinity for Asch and the sensitivity to insecticide of acetylcholinesterase in 3rd instar larvae are significantly lower than that in 4-day-old larvae.

幼虫从1日龄生长到4龄时，单头幼虫的羧酸酯酶、谷胱甘肽转移酶、乙酰胆碱酯酶活力急剧增长，4龄幼虫相对于1日龄幼虫，HJ-R、HD-S上述3种酶系的活力分别增长了148、172.6、65.6倍和203、60.9、77.4倍；生长过程中，全酯酶、乙酰胆碱酯酶的性质也发生变异，特别是从4日龄生长到3龄时，乙酰胆碱酯酶的米氏常数、双分子速率常数均发生明显的改变，3龄幼虫乙酰胆碱酯酶对底物的亲和力以及对杀虫剂的敏感性显著低于4日龄幼虫。

One may need to entertain the hypothesis that based on the affinity between the network-like structure of comprehension and that of hypermedia products, intensive interaction with the latter might facilitate the construction of rather shallow associationist cognitive networks. Such networks would consist of trivial, frail connections, having no intellectual merit.

我们或许需要思考这一假设：由于意义理解的网络结构与超媒体产品的结构具有相似性，因此，学习者与超媒体产品的深入交互可能会促使学习者建立一种很肤浅的联想性的认知网络，这种网络之中所包含的是一些不甚重要的、虚弱的联系，而没有任何智慧的价值。

In a period, most commonly the first ionization energy increases with increasing atomic mass, while the change in electron affinity does not show a clear trend.

P14 在一个周期内，通常第一电离能随原子量的增加而增加，而电子亲和能的变化却没有明显的规律。

When doping the rare earth elements in nano-TiO〓, the relationships between the photocatalytic activities and the ratio of electronic affinity to ionic radius of doped atomic ion were studied.

在稀土元素对纳米TiO〓光催化剂的掺杂研究中，发现催化活性与掺杂元素的稳定氧化态的电子亲和势与离子半径的比值Ea/r有较好的相关性，而与Ea/r〓的相关性相对较低。

It is simply an acute attunement to what I like to call, the "death energy", an affiliation and natural affinity some people have for the current of transition.

这是一个单纯的急性能配合我在此呼吁，"死亡能量"父亲和自然的一些人对当前的过渡。

他们拥有尼格利陀人的亲和力，是既害羞又好客的民族，原始语言则属于南岛语系。

The studies presented here provided the antifungal lead compounds. Because the affinity of the lead molecules for CYP51 was mainly attributed to their nonbonding interaction with the apoprotein, which was different from the azole antifungal agents.

先导分子通过与靶酶活性腔氨基酸残基的非共价键结合产生抗真菌作用，避免与血红素辅基Fe原子发生配位结合，为一类具有新作用机理的非氮唑类抗真菌先导化合物。

Because of their chemical affinity, one base must be paired with another, and this makes them very unstable.

由於盐基阴阳相吸的作用力，必须与另一半组合成对，所以很不稳定。

As it turns out, I have this affinity for beachfront property.
