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.

Stability Analysis for Time-delay Systems via a Novel Negative Condition of the Quadratic Polynomial function

This paper studies the stability analysis problem for time-varying delay systems. An appropriate Lyapunov-Krasovskii functional (LKF) is constructed where its derivative is a quadratic polynomial function of the delay. A novel negative condition of the mentioned quadratic function with two variable parameters is developed to ensure that the LKF derivative is negative, reducing conservatism on some similar results. Besides, an extended version of Bessel-Legendre inequality is introduced to be employed in the stability analysis of time-varying delay systems. Then, some stability criteria with less conservatism are derived for two kinds of the time-varying delay. Finally, the effectiveness of the proposed stability criteria is demonstrated through three examples.
