spin pairing

The temperature dependence of the spin-lattice relaxation rate and the Knight shift indicate d-wave pairing, which brings about the extended quasiparticle states outside the vortex cores.

核自旋晶格弛豫率以及奈特位移的实验结果显示，超导态的电子配对是d波单态配对.d波能隙函数里存在节点，使得准粒子从涡线中心漏到涡线外面。

Spin Pairing and Chemical Bonding

自旋配对与化学成键

In the low density region, superconducting pairing of singlet and triplet state will open up a spin energy gap and form a spin gap state.

在电子占据密度较小的区域，单重态与三重态超导配对会打开一自旋能隙，形成一自旋能隙态。

Therefore, the spin pairing is not cause of the formation of covalent bond, it is not also condition of first determining, the spin pairing is the only particularity of covalent bond of two electrons.

因此，电子自旋配对不是共价键形成的原因，也不是先决条件，电子自旋配对只是双电子共价键的一个特点。
