查询词典 proportion

In terms of absorption proportion, element N was the nutritional limiting factors in spring, summer and autumn, while element P in winter. However, both became the nutritional limiting factors in all years in term of absolute absorption.

从浮游植物吸收N、P 的配比分析， N为春、夏、秋3 季的营养限制因子， P 为冬季的营养限制因子，但从N、P 的绝对值看， N 和P 都是全年的营养限制因子，因此其水质营养类型属于亚热带贫营养型。

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。

In the research of prescription, through the experiments we knew the influence from the Nb_2O_5 or Y_2O_3 single donor doped on high-temperature PTC ceramic, and got the curve graph drawing the resistivity and mixing quantity. In order to restrain lead volatilize and mix the rang of donors to neutralization the harmful acceptor impurity in raw materials, adopt the prescription design of Nb_2O_5 and Y_2O_3 double donors-doped. From the result, we know that regulation proportion of Nb , Y double donors, can make high-temperature PTC ceramics semiconducting, the pottery demonstrates good electric performance.

为了能够更有效的抑制铅挥发，并且使掺杂范围能够更好的调节，以"中和"原材料中的有害受主杂质，在配方设计中采用了Nb_2O_5和Y_2O_3双施主掺杂的配方，由结果可知，适当的调节Nb、Y双施主掺杂总量及Nb、Y掺杂比例，可以使高温PTC陶瓷充分的半导化，陶瓷表现出良好的电性能。
