基于能值的鄂尔多斯市水资源生态经济系统可持续发展动态分析

运用能值理论和分析方法,分析了鄂尔多斯市2000-2009年水资源生态经济系统能量流动规律,构建了其能值综合图,计算评价了水资源开发利用状态及其系统可持续发展状况。分析结果表明,鄂尔多斯市经济社会发展主要依靠不可更新资源的投入,且对不可更新资源投入的依赖程度不断增大,水资源投入能值所占比重逐渐减小;鄂尔多斯市在市场贸易中处于明显不利地位,经济发展尚处于高消耗、高增长的发展阶段,工业化水平还有待提高。2000年以后鄂尔多斯市经济系统虽然富有活力和发展潜力,但是随着当地经济发展对不可更新资源的依赖不断增大,系统有向消费型经济系统快速发展的趋势。鄂尔多斯市应加快重点工业产业技术更新和产品升级,延长产业链。

胺鲜酯(DA-6)浸种对盐胁迫下白三叶种子萌发及抗盐性的影响

以白三叶(Trifolium repens L.‘Haifa’)为研究对象,研究了0.8 mmol·L^-1胺鲜酯(DA-6)浸种处理对白三叶种子在盐胁迫条件下萌发的影响,并对DA-6诱导的耐盐机理进行初步研究,为白三叶的栽培管理提供参考。结果表明,DA-6浸种显著提高了盐胁迫下种子的发芽势、发芽率、活力指数、发芽指数、茎长和鲜干重(P<0.05)。盐胁迫显著诱导了游离脯氨酸和可溶性糖的积累,降低了细胞渗透势(P<0.05)。此外,盐胁迫导致了萌发种子中活性氧(超氧阴离子和过氧化氢)和膜脂过氧化产物丙二醛含量显著增加,电导率显著升高(P<0.05)。DA-6浸种前处理显著提高了胁迫下抗氧化酶(SOD、POD和APX)的活性,增幅分别为33.0%、31.9%和49.1%,这有效地缓解了由盐胁迫引起的氧化损伤,有利于幼苗稳定细胞膜(P<0.05)。本研究表明DA-6浸种处理通过增强抗氧化防御并降低细胞氧化伤害,从而提高盐胁迫下白三叶种子的萌发特性和胁迫耐受性。     

继电保护压板的智能校核方法

继电保护压板位置一般与一次设备运行方式相关,在一次设备运行方式改变时,有时需要改变压板的位置进行匹配。实际运行操作中因压板位置投退错误,已导致多起事故发生。为了避免保护压板出现漏投、误投现象,从搜索一次元件状态、运行方式的角度出发,在采集压板位置信息基础上,提出了一种压板位置与一次元件运行方式匹配状态的智能校核方法。根据一次元件的运行状态及相应的压板整定规则,生成一次元件压板位置关联规则库,利用变电站开关状态信息在变电站倒闸操作后自动识别一次元件状态,与一次元件压板规则库进行比较,当出现不一致时给出报警提示信号,实现了压板位置的智能校核。通过对实际工程中变压器运行转检修操作任务的分析,验证了所提方法的有效性。     

Antioxidant,anti-amylase and anti-glycation potential of brans of some Sri Lankan traditional and improved rice (Oryza sativa L.) varieties

Brans of 23 traditional and 12 improved (both red and white) rice varieties in Sri Lanka were screened for anti-amylase and anti-glycation activities in vitro. Varieties which showed the highest inhibitory activities at screening were further investigated for anti-glucosidase and glycation reversing as anti-diabetic properties. The same varieties were studied for selected antioxidant properties. Significantly high anti-amylase and anti-glycation activities were observed for bran extracts of red varieties compared to white varieties at screening. Traditional red rice varieties, Masuran, Sudu Heeneti, Dik Wee and Goda Heeneti, exhibited significant and dose dependent anti-amylase, anti-glycation and glycation reversing activities. These varieties also showed marked antioxidant properties. It is concluded that brans of Sri Lankan traditional red rice varieties Masuran, Sudu Heeneti, Dik Wee and Goda Heeneti may be potential food supplements for diabetes.     

The analysis of China wind power industry

The development course of China wind power industry is reviewed by six stages. National policies on wind power industry are elaborated from the aspects of laws & regulations, planning, finance & taxation and electrovalence policy. And these policies have played an important supporting and regulating role in the development of wind power industry. The development status of China wind power industry is analyzed based on wind turbine installed capacity, wind power output and their growth rate. It is explained that national wind turbine manufacturers have kept developing and become strong by the data of new global installed capacity share of mainland wind turbine manufacturers in 2013 and the new global market share of 8 domestic enterprises among the world top 15 wind turbine manufacturers. But there are still 5 key problems which influence the development of national wind turbine need to be solved, including lack of top-level design, abandon and restriction wind power seriously, lack of R&D abilities, some of the key parts relying on imports and wind turbine facing a quality guarantee dilemma. Taking Sinovel Wind Group Co. Ltd. and Xinjiang Goldwind Sci & Tech Co. Ltd., the two leading companies as an example, their performance is analyzed and it’s pointed out that the wind industry must keep vigilant after the overspeed development. The enterprises should try to avoid neglecting cultivating their inner core competitive ability, including technology advancements and products reliability. Occupying the market with low price competition and expanding blindly is also not desirable. At last, the development prospects of our country’s wind power industry are analyzed and three proposals are put forward.     

桃铁离子吸收动力学研究
