氧化价态

作者认为，在La-Sr-Cu-O超导体中，类低氧化价态的Sr可能对高Tc有利。

We believe that the low valence-like oxide state of Sr may be beneficial to high Tc .

实验结果表明：正交晶体结构、氧含量、Cu的氧化价态，以及金属&半导体（绝缘体）相变等都只是决定Tc的表观因素；

It is shown that all the orthorhombic crystalline structure , oxygen content , oxidation state of Cu atoms , and metal-semiconductor ( insulator ) transition etc. are only the extrinsic factors determining Tc .
