浅圆仓通风储粮技术研究   总被引:1,自引:1,他引:0  
浅圆仓通风储粮技术在我国尚属一门新的科学技术,过去很少有人研究和报道,但随着浅圆仓仓型的建造,浅圆仓储粮管理上一系列技术问题需要急待解决,从而为新仓储粮管理和粮食安全度夏提供有效保证。本项研究正是从这方面开始,探讨浅圆仓通风储粮技术上一系列问题,供今后浅圆仓通风储粮作为技术参考,使浅圆仓储粮管理更合理、更科学。  相似文献

目前浅圆仓在使用中存在主要问题有:进粮时产生的柱状杂质区和粮食自动分级、结拱、挂壁、局部粮情监测困难、结露、出仓时粮食残留多等.所以浅圆仓要安全储藏粮食,尚需粮食工作者不断地发现、解决问题,不断地探索、总结经验,不断地改进、完善浅圆仓的建造工艺、储粮设施.根据国内近几年浅圆仓储粮的经验,结合浙江省舟山储备中转粮库浅圆仓储粮实际情况,探讨浅圆仓在设计建造及使用时应该注意的问题,以便在源头上解决问题.  相似文献

1概述 浅圆仓又称矮圆仓,是一种仓体高度与直径之比小于1.5的圆筒式地上粮仓。浅圆仓多为平底仓,仓壁主体多为钢筋混凝土结构,厚度为250-270mm。 浅圆仓在国外已有几十年的应用历史,但在国外多用于中转或短期储藏。90年代以后,我国利用世界银行贷款改善粮食流通项目,将浅圆仓作为一种新的仓房类型引入国内,主要用于粮食流通。1998年以来在中央直属储备粮库建设中新建了一部分主要用于粮食储备的浅圆仓。 浅圆仓具有直径大(20~40m)、粮层深(12~40m)、单仓储量大(5000-20000t)、单位…  相似文献

FDI(Foreign Direct Investment),a component of a country's national financlal accounts,is investment of foreign assets into domestic structures,equipment,and organizations.It does not include foreign investment into the stock markets,concession and subcontract.FDI iS thought to be more useful to a country than investments in the equity of its companies because equity investments are potentially "hot money"which can leave at the first sign of trouble,whereas FDI is durable and generally useful whether things go well or badly.  相似文献

Not long ago, the National Bureau of Statistics released its 2007 Macro Economy Index. Social consumption retail sales reached RMB 8.9 billion, increased by 16.8 percent over the previous year, or 3.1 percentage points higher; the whole investment in social fixed assets was valued RMB 13.7 billion, a year-on-year increase of 24.8 percent, that is 0.9 percentage points higher; and trade surplus amounted to RMB 24.7 billion, rising by 47.7 percent compared with the same period last year, 26.3 percentage points falling over the increasing speed last year. According to preliminary estimates, GDP for the year was RMB 24.67 trillion, up by 11.4 percent from the previous year,  相似文献
