单质分子和氮化物与卤化物,其核间距与力常数都表现有相似的行为。
The internuclear distances and force constants of the elementary molecules as well as of the nitrides and halides, exhibit a similar behavior.
而我们就能更清楚地看到这些,如果我们画出,能量随核间距的变化曲线。
And we can actually better visualize this if we plot how that energy changes as a function of internuclear distance.
因此,当我们考虑一个键的长度的时候,这就应该是我们的键长,这是合理的,因为体系会在核间距达到这一距离时,能量到达最小值。
So, when we think about a bond length, this is going to be the length of our bond here, that makes sense because it's going to want to be at that distance that minimizes the energy.
所以,比如这有一个钠离子,和一个氯离子,它们中心与中心间的距离,我把它设为,这是原子核和原子和的间距。
So, for example, if I have a sodium ion over here, and I have a chloride ion over here, where the distance from center to center r I'm denoting as r, this is nucleus to nucleus separation.
目的探讨肿瘤内毛细血管间距(ICD)和增殖细胞核抗原(pcna)与宫颈癌放射敏感性的关系。
Objective To investigate the correlationship between proliferating cell nuclear antigen (PCNA), intercapillary distance (ICD) and radiosensitivity in uterine cervical cancer.
另外,基于(核)最大间距准则,本文提出了一组具有统计不相关性的最优(核)鉴别矢量集的计算方法。
Besides, based on the (kernel) maximum margin criterion, new algorithms of statistically uncorrelated optimal (kernel) discriminant vectors for feature extraction is presented in this paper.
