元素的

Nature, most elements have two or more isotopes, the same kinds of elements in the quality of the various isotopes of different, but the types and proportion constant (except for radioactive elements). In 1961, the carbon content of the most abundant in nature, a kind of isotope, carbon-12 atom of a quantity and quality of C as a 12 mass units to it as "benchmarks" for all isotopes of an element according to the average abundance The ratio of the benchmark is the atomic weight of this non-prime, that is listed in the periodic table of atomic weights.

自然界中大多数元素都有两种或更多的同位素，同种元素的各同位素质量不同，但其种类和比例是恒定的。1961年，把碳在自然界含量最丰富的一种同位素，碳12的一个原子的质C量定为12个质量单位，把它作为"基准"，某种元素的所有同位素按丰度的平均值与基准之比，就是这种无素的原子量，即元素周期表列出的原子量。

论文的第一部分在分析了金属半径、阳离子半径、元素标准熵、原子折射度等与元素电子构型的定量关系后，鲜明地提出：晶体化学参数与元素的电子构型之间存在定量关系，元素的一些性质与周期表之间可以有统一的定量表述方式。

The spontaneous fission is primary factor restricting numbers of transuranium elements .

超铀元素的存在受到诸多因素的限制，而自发裂变是限制超铀元素数目的最主要因素，从自发裂变限制方面分析，超铀元素的存在界限大体在Z＝120号元素以内。

The results show that dynamic leaching of heavy metals increases with decreasing pH values on the whole, but the relativity is not significant. The leaching concentration is negatively correlated with time. The calculation results show that the elements with the largest cumulative leaching amount are Fe, Mn, Zn and As, and those with the smallest amount are Pb, Sn, Hg and Cd. The elements with the highest stage lixiviating rate are Ni, Co, Cr, Mn, Cd and Cu, and that with the lowest rate is Fe. The elements with the highest values of cumulative lixiviating rate and cumulative lixiviating intensity are Cr, Mn, Co, Ni and Zn, and that with the lowest ones is Fe.

结果表明，重金属元素的动态浸出整体随pH值下降而升高，但相关性不明显，浸出浓度与时间整体上呈负相关关系；浸出总量效果较好的元素为Fe、Mn、Zn、As，较差的为Pb、Sn、Hg、Cd，其他元素中等；阶段浸出率较高的元素有Ni、Co、Cr、Mn、Cd、Cu，较低的元素有Fe，Sn、Zn介于中间水平；累积浸出率和累积浸出强度较高的元素有Cr、Mn、Co、Ni、Zn，较低的元素为Fe，Cu、Cd、Sn居于中间水平。

Oxygen plays critical roles in lubrication mechanism. Oxygen affects the lubrication mechanism of additives all along, whether in sulfurized vegetable oil fatty acids containing active element or not in hydroxy vegetable oil fatty acids with pure carbon, hydrogen and oxygen not containing active element.

氧元素在润滑机理中有着关键作用，无论在含活性元素的硫化植物油脂肪酸，还是在不含活性元素的纯碳、氢和氧的羟基植物油脂肪酸中，氧元素始终影响着添加剂的润滑性。
