Whereas the record-breaking ortho-diethynylbenzene dianion has a proton affinity of 440 kilocalories per mole.

而破纪录的邻二乙炔基苯双阴离子的质子亲和力为每摩尔 440 大卡。

More precisely, oxygen binding increases the affinity of hemoglobin for oxygen.

更准确地说，氧结合增加了血红蛋白对氧的亲和力。

The affinity of hemoglobin for oxygen is decreased in our tissues by several physiological factors.

血红蛋白对氧气的亲和力在我们的组织中由于多种生理因素而降低。

The affinities of all the beings of the same class have sometimes been represented by a great tree.

同一类所有生物的亲缘关系有时用一棵大树来表示。

At a low PO2, where the affinity of hemoglobin for oxygen is also low, the curve rises slowly.

当PO2较低时，血红蛋白对氧的亲和力也较低，曲线上升缓慢。

Hemoglobin exhibits what we call cooperative binding, as oxygen binding increases the affinity of hemoglobin for more oxygen.

血红蛋白表现出我们所谓的协同结合，因为氧结合增加了血红蛋白对更多氧的亲和力。

The real affinities of all organic beings, in contradistinction to their adaptive resemblances, are due to inheritance or community of descent.

与适应性相似不同， 所有有机生物的真正亲缘关系是由于遗传或血统共同体造成的。

As PO2 increases and oxygen binds to hemoglobin, the affinity of hemoglobin for oxygen increases, and now we see the curve rise sharply.

当PO2增加，氧与血红蛋白结合时，血红蛋白对氧的亲和力增加，现在我们看到曲线急剧上升。

On these same principles we see how it is that the mutual affinities of the forms within each class are so complex and circuitous.

根据这些相同的原则， 我们可以看到每个类中形式的相互亲和力是如何如此复杂和迂回的。

It is important to note that the increased affinity of hemoglobin results from a conformational change, or a change in the structure of hemoglobin when the oxygen binds.

重要的是要注意，血红蛋白的亲和力增加是由构象变化或氧结合时血红蛋白结构的变化引起的。

In the literal sense of the word, no doubt, natural selection is a false term; but who ever objected to chemists speaking of the elective affinities of the various elements?

毫无疑问，从字面上看， 自然选择是一个错误的术语；但是谁曾反对化学家谈论各种元素的选择性亲和力呢？

It would be difficult to give any rational explanation of the affinities of the blind cave-animals to the other inhabitants of the two continents on the ordinary view of their independent creation.

按照它们独立创造的普通观点，很难对盲眼洞穴动物与两大洲其他居民的亲缘关系做出任何合理的解释。
