Production speed too slow, the bottom again, such as nickel oxide layerin gold slot oxidation (or gold reduction), peel tin.
产速太慢，底层再次氧化，如镍层在金槽氧化(或金还原)，剥锡。

A novel method based on potential function theory is given in this paper to formulate the analytic solution of slot antenna on electrical sphere coated with dielectric layer.
给出了用位函数方法推导介质覆盖导电球上缝隙天线辐射场严格解的过程。

In this paper set forth the method of symmetric design for three-phase double layer asymmetric fractional slot winding.
