摘要
With the advent of high-T<sub>C</sub> superconducting（HTS）materials whose superconducingtransform temperature supasses 77K which is the boiling temperature of LN<sub>2</sub>,the high tideof research of HTS materials comes along in order to develop the HTS materials withhigher superconducting critical temperatures,less surfaced resistances at microwavefrequencies,and stabler superconducting properties.Through great efforts of
