长江经济带工业能源效率空间差异及影响因素研究

运用能源强度、离散系数、莫兰指数综合测度1999—2013年长江经济带工业能源效率空间差异及发展趋势,并建立面板托宾模型探索工业能源效率影响因素,分析表明：长江经济带省际工业能源效率从下游至上游存在梯度差异,空间差异由趋异向趋同转变,省际工业能源效率呈现空间集聚特征;长江经济带工业能源效率与经济发展水平、工业比重、政府影响力（财政支出比重）、电力消费比例、研发投入力度呈正相关,与能源消费比例、煤炭消费比例呈负相关,与对外开放水平的关系不明确。提高工业能源效率,长江经济带上游地区应提高研发投入在国民经济中的比重,下游地区要加快能源消费结构的优化升级,而中游地区工业能源效率受能源消费比例影响明显,提升潜力较大。

多源媒体情绪传播影响了企业策略性专利行为吗？

以我国2008—2020年A股上市公司为样本,考察多源媒体积极情绪传播对企业策略性专利行为的影响。研究发现,多源媒体积极情绪传播通过管理层迎合和管理层防御机制对企业策略性专利行为产生正向影响。进一步研究表明,控股股东两权分离强化了管理层迎合效应的发挥,证监会减持新规的出台并未弱化管理层防御效应的发挥。多源媒体积极情绪传播引起的企业策略性专利行为使得企业产品竞争力和企业竞争地位下降。

电源故障处理几例

武钢轧板厂二棍辅传动辊道采用17英寸的插件板可控硅直流调速模拟系统。调试完后几年的运行一直都比较稳定。后出现不操作，辊道也会自己转起来。首先检查操作电源，由220VAC整流成24VDC，发现24VDC的零线是接地的，在检查插件板基板的零线时却发现与系统24VDC的零线不通，而且对系统地有电压存在。估计是零线断开了，模拟系统没有地，也无法将速度锁零，重新接好地后，系统恢复正常。
