浅析江西农民增收的影响因素

江西农民收入在新世纪以来有了可喜的变化,但必须看到,江西农民人均纯收入与江西生产总值的增长,以及与城镇居民可支配收入的增加相比,与东部发达省份的农民收入相比,甚至与中部地区大部分省份相比,其增加还是缓幔的。江西省委、省政府历来十分重视“三农”问题。新时期江西农民收入增长比较快,但幅度不大,具体情况是工资性纯收入和外出务工收入增加较快,一产纯收入仍占主要份额,地区发展不平衡。影响江西农民收入的因素有：二、三产的比重太少,农民非企业组织收入少,农民家庭收入增长慢。

Cation interdiffusion between thick film of YBa2Cu3O7-δ and ceramic substrate

Thick films of superconducting oxides, YBa₂Cu₃O_7-, were successfully made by conventional screen-printing technology on Al₂O₃, MgO, and ZrO₂ substrates. Interdiffusion between the superconductive film and substrate was investigated using analytical electron microscopy. The results indicate that MgO and ZrO₂ are superior to Al₂O₃ for substrate materials.
