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。

The results indicate that the effect of alloying elements V and Cr on mechanical properties at room-temperature, creep behavior and microstructures are similar. With increasing contents of V and Cr, their mechanical properties produce little change, the creep resistant property decreases and microstructure grows, which is mainly due to their characteristics of β-stability element and smaller atomic radius compared with Ti. On the contrary, the effects of V and Cr on the thermal stability are quite different. With increasing V content or decreasing Cr content the thermal stability for the alloy becomes better, which may be due to the different solution characteristics of V and Cr element in titanium alloy that V belongs to isomorphous β-stability element and Cr belongs to eutectoid β-stability element.
结果表明:合金元素V和Cr对Ti40合金室温力学性能、蠕变行为和组织的影响具有相似性,即随V和Cr含量的降低,合金室温综合力学性能变化不明显、抗蠕变能力减弱、组织粗化:这与V和Cr同属于β稳定元素、且原子半径都小于Ti原子有关;而V和Cr对于热稳定性能的影响则完全相反,V含量的增加或Cr含量的降低含金热稳定性能优化,其主要原因可能与V属于同品型β稳定元素而Cr属于共析型β稳定元素有关。

Total percent of carbon, nitrogen and phosphorus in Engraulis japonicus varied from 46.3% to 60.5%. And carbon content of Engraulis Japonicus was increasing and phosphorus was decreasing when growing from larvae to adult. However, there was not significant difference to nitrogen in different stages. Differences of nutrient contents in different life stages may be caused by changes in allocation of materials for growth within the body.

Abundances of compatible and weakly incompatible elements in melt vary greatly when P values chanse, so P values of these elementscan not be replaced by D0 in the melting model. However, abundances of moderately and highly incompatible elements only show small variation when P values are different. It is thoughtthat P values of moderately and highly incompatible elements are equal to D0 values in the nonmodal partial melting model.
当P值不同时,相容元素和弱不相容元素在熔体中的浓度出现大的变化,因此,在模型中这些元素的P值不能用D0代替;然而,P值的变化仅造成强不相容及中等不相容元素的浓度小的变化,可以认为强不相容与中等不相容元素的P值约等于D0。
