    刚过去的“十二五”时期中国经济总量稳居世界第二,人均国内生产总值增至7654美元。改革开放以来,我国经济发展成果世界瞩目,居民生活水平和质量得到显著提高。然而在经济高速发展的同时,我国城镇和农村二元经济结构愈发明显,特别是收入差距逐渐扩大,虽然近年来略有下降,但仍处于有风险的差距水平。城镇和农村收入差距导致了一系列的社会问题,农村消费不足、城乡心理失衡、二元特征更加明显等等。党和政府高度重视城镇和农村差距问题,在“十三五”规划中不仅提出了国内生产总值和城乡居民人均收入比2010年翻一番的总体目标,同时强调要推动城镇和农村协调发展,缩小城镇和农村的收入差距。要实现城乡协调发展,就得找到症结所在,...China has been remaining the largest economy stably over the Twelfth Five-Year Plan period.

    磷是生物体所必需的大量元素之一,其参与构成的化合物、生物大分子广泛参与到各种生命活动当中,有重要的生理功能。但是土壤中可供植物直接利用的磷含量十分的有限,致使磷成为植物生长和粮食产量的主要限制因素。因此,研究植物磷积累的分子机制,寻找促进植物磷营养的方法有重要的意义。 一氧化氮(NO)作为一种气体信号分子,参与调节植物多种代谢活动。虽然一氧化氮参与植物非生物胁迫的调节作用已经得到证实,但是其对磷吸收的调节机制尚不明确。本试验以水稻为材料,通过施加NO供体硝普钠(sodiumnitroprusside,SNP)、一氧化氮合成酶(nitricoxidesynthetase)抑制剂(Nw-nitr...As one of the most important macro nutrient for biology, phosphorus composes many materials showed a widely biological function in metabolism. In the soil, only phosphate can be used by plants directly and exists in a shortage, leaving phosphate one of the limits for plant growth and yield.

    公平性问题在不同时代、不同文化、不同宗教信仰与政治体制下,内涵与标准各不相同,对于公平的研究领域也涉及到人类社会的方方面面,其中就包括公共服务的公平性问题。在公共服务的公平性研究领域中,作为公共服务物质载体的公共服务设施具有很强的空间属性特征,因此公共服务公平性的研究更多将着眼点放在公共服务设施空间公平性的研究上。城市交通运输系统作为重要的公共服务设施,是整个社会经济发展系统中的重要组成部分,为物质资源的流通以及全体社会成员参与各类社会经济活动及社会交往活动提供基础条件与机会,因此交通公平一直是公共服务公平性研究的热门领域。 在国家提出“基本公共服务均等化”发展战略的大背景下,通过对国内外有...In different times, different cultures, different religions or political systems, the connotation and standards of equity is different.
