摘要：随着人民币跨境使用的深入发展,人民币离岸市场迅速成长,对国内宏观经济产生了一定的影响。本文通过实证研究人民币跨境流动对国内宏观经济的影响,从人民币升/贬值预期对离岸市场发展的影响、境外市场人民币自循环不畅和离岸市场缺乏人民币流动性补充安排等三个方面对人民币离岸市场与在岸市场发展过程中存在的问题进行了分析。针对人民币离岸市场与在岸市场发展过程中存在的问题,通过设计人民币离/在岸市场间的循环机制,提出了促进离/在岸市场人民币资金良性循环的建议。

摘要：针对斜井钻井成本相时常规油井造价昂贵,对斜井钻井及修井设备要求较高等问题,南 阳石油机械厂研制了国内第一台斜井修井机,并设计制作了斜井井架。已成功通过现场工业性试验。

摘要：In order to investigate characteristics of nitrogen use efficiency of CMS line Rong 18A, four hybrid rice combinations （Rong18 You188, Rong18 You198, Rong18 You662, Rong18 You908） derived from CMS line Rong 18A were used as experimental materials with Ⅱ You838 and Gangyou725 as controls. A split-plot experimental design was performed with four nitrogen fertilizer application rates to analyze the effects of different nitrogen fertilizer application rates on the yield and yield component factors of rice. The results showed that nitrogen fertilizer could significantly increase effective panicle number to improve rice yield. The increment in rice yield per unit nitrogen fertilizer application rate demonstrated a descending trend with the increase of nitrogen fertilizer application rate. Under low nitrogen levels, hybrid rice combinations derived from Rong 18A exhibited relatively high nitrogen use efficiency and showed remarkably high nitrogen use efficiency under low nitrogen levels.
