成对

While the earring has been used alone or in pairs since the dawn of man, its use and acceptance has varied with cultural and fashion trends.

虽然耳环已开始采用曙光人单独或成对出现的，它的使用和接受都有不同的文化和时尚潮流。

Substances whose electrons are all spinpaired,by contrast,are weakly repelled by magnetic fields and are said to be diamagnetic.

物质的电子都是两两自我成对的，与此相反，是弱击退了由磁场，并说是抗磁性。

At the normal state, porphyrin molecules do not have EPR signal. However, light excitation may cause a transition of porphyrin molecules from singlet to triplet. At the same time, the change from diamagnetism to paramagnetism occurred to porphyrin molecules. In this case, the two un-paired electrons are nearby each other and cause a strong interaction, giving EPH signal with sharp peak at g = 2.000. The g value increased with an increase in electron cloud density.

常态下卟啉分子没有EPR信号，在光的激发下，卟啉分子由原来的逆磁性分子变成顺磁性的激发三重态分子，这种激发三重态分子在分子轨道上具有两个未成对电子，这两个电子相距很近，彼此之间发生很强的相互作用而产生电子，它的g值随卟啉共轭体系平均电子云密度增大而变大。

Any of various paired spherical bacteria, including those of the genus Diplococcus, some of which are pathogenic.

双球菌一种成对球形细菌，包括双球菌属的细菌，其中一部分是致病的

However, a left movement of the right eye allows the eyes to conjugate; hence the diplopia disappears.

然而，右边眼睛往左侧看的时候，眼睛可以成对的注视著，因为复视已经消失了。

Although the term is not a technical one, we can refer to these duplicated chromosomes as making up a doublet

虽然这个术语不是技术语，但是我们能称这些成对的染色体为正在组成骈联体。

The most highly prized sight in this Kapalai dive however is the dragonfish or pegasus found in pairs on the sandy floor.

然而，在这个卡帕莱潜点中最受高度评价的景象就是龙鱼或海蛾成对出现在海底沙地上。

Inform ation.If an aggregate data elem ent contains a lis t of values, then each of these values

如果集合资元素包含一组资值，则每一个资值应为成对的次元素值组

They often howl at the shining Endor planet in the night sky, and they typically hunt in pairs.

它们常在灿烂的安铎星夜晚嗥叫，并常成对的出猎。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
