The results show that for collectors of the same kind, their selectivity is in linear relationship with HOMO energy and can be predicted well. For collectors of different kinds, it can be concluded from shape of HOMO and atomic HOMO density that the selectivity of ethoxycarbonyl thionocarbamates is better than the one of xanthogen formates.

结果表明：对于同种类型的捕收剂，其选择性与HOMO能量呈线性关系，依据HOMO能量能较准确地预测这两种捕收剂的选择性能；对于不同种类的捕收剂，通过对HOMO形状以及组成原子的HOMO密度的讨论可知，乙氧羰基硫氨酯类捕收剂的选择性能要比黄原酸甲酸酯类捕收剂的强。

We have discussed the changes of spin density and atomic charge on B-site as the crystal parameters are individually expanded or compressed from 0.02% to 0.2%(and, from 0.5%~5.5%).

单晶格及双晶格的计算中，虽然随著晶格膨胀或压缩的维度的增加，Mn中的电子自旋密度和原子电荷的变化均趋缓，但整体而言电子自旋密度仍然受到晶格参数的高度影响。

It can be seen that the bulk modulus depends mainly on electrons per atomic volume and mass density, while covalent structure of chemical bonding and N content make more contribution to theoretical hardness, and appropriate content N—N covalent bonding in the same direction tends to increase the shear modulus of nitrides.

说明在Tc的氮化物中，其体弹模量与材料的晶体结构、平均每个原子上的电荷密度和材料的质量密度有关；化学键的共价性结构和氮元素的含量对理论计算硬度有正作用；而剪切模量的极大值则与其层状结构及体系中一定量的方向基本一致的N—N键相关。

Early chemists had to use indirect means for determining the atomic mass of an element .

早先的化学家只得用间接的方法来确定某种元素的原子质量。

If one was to look at the Table of Periodic Properties of the Elements, one would notice that the atomic structure of each element is illustrated.

如果是看表的周期性质的元素，人们会发现，原子结构的每个元素说明。

Results consistent with those based on molecular dynamic and atomic finite element methods confirm the feasibility and validity of the presented constitutive model.

所获得的与分子动力学模拟和原子有限元计算相一致的结果证明了目前所发展的模型的可行性和正确性。

The fact that only certain colors appear in an element's atomic emission spectrum indicates that only certain frequencies of light are emitted.

事实上，只有特定的颜色在一个元素的原子发射出现光谱表明，只有根据某些频率的发射。

Of course, a periodic table cannot be complete unless it has the atomic mass of the element and so this table uses the rank of the web page as it's "mass".

当然，在元素周期表中，可以是不完整的，除非它拥有原子质量的元素，所以本表使用秩该网页，因为它的"地下"。

The second part of this thesis mainly deals with the classification problems of heavy element atomic spectral energy levels.

本文的第二篇论述了将模式识别-人工神经网络方法的PCA-BPN（主成分分析-反传神经网络）和PLS-BPN应用于CmⅠ、UⅠ、CmⅡ等重元素原子光谱能级的分类研究工作，明确指认了许多前人应用早期模式识别方法以及CPN方法无法确认或错误指认的未知能级所属的电子组态，取得了较好的效果。

Atomic element number 101, ends in ium.

"|它的原子序号码是101 字尾是"IUM

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。
