基于北京师范大学劳动力市场研究中心的调研数据,研究对“互联网+”能否促进返乡创业企业经营绩效进行实证检验。结果显示,“互联网+”能够显著提升返乡创业企业经营绩效,且返乡创业者的社会资本能够显著促进“互联网+”积极作用的发挥。异质性分析表明,“互联网+”可以从生产、销售、第三方服务三个方面提升返乡创业企业经营绩效,这一作用在中西部返乡创业企业,生存型返乡创业企业,以及处于第二产业、第三产业的返乡创业企业中更为明显。基于融资渠道、信息渠道和风险渠道的机制分析表明,“互联网+”能够显著增强返乡创业企业的再融资能力,降低融资成本,提升返乡创业者的风险承受能力。

阳明经腑热,大肠宿食糟粕、肠垢后胀气,热过极没有出路,形成了肠痈。肠热不是一朝一夕形成的,肺与大肠相表里,肺病不能离开大肠,肠病不能离开肺。肺居上,全靠脏腑的供养,外有太阳经保护。大肠热往上传,二阳热长期携带,二阳热往上传,加上少阳胆也有热,三阳热同时传给肺,肺就病了。葛根汤是是二阳合病的方中之祖,治疗三阳外感二阳病携带。从葛根汤的药物组成来看,它是太阳中风、太阳伤寒的合并方,是太阳病未尽、阳明又病的二阳合病之方。治疗肺癌用六经辨证的思路,五方合一,战胜外邪,方能起死回生。

柴达木盆地厚达万米的新生代沉积物记录了青藏高原东北部隆升和古气候变化信息.本文基于盆地北缘大红沟剖面高分辨率的磁极性年代标尺,对该剖面古‒新近纪河湖相沉积物进行了颜色测量,首次获得了柴达木盆地长时间尺度(52~7 Ma)的色度参数变化序列.在此基础上,综合沉积相与区域构造和古气候记录,探讨了影响河湖相沉积物颜色参数的因素及柴达木盆地古‒新近纪的气候演变.结果表明,大红沟剖面沉积物颜色的变化与全球温度变化趋势基本一致,说明温度是影响颜色参数,特别是红度(a*)的主要因素;沉积相变化,尤其是水面上、下的氧化‒还原环境变化对颜色参数也有重要影响.根据色度参数在时间标尺上的变化,将柴达木盆地的气候变化划分为8个阶段:(a)52.0~44.2 Ma湿热,(b)44.2~33.7 Ma在干湿波动中逐渐变干,(c)33.7~27.1 Ma进一步变干,(d)27.1~19.7 Ma逐渐变湿,(e)19.7~17.0 Ma较干旱,(f)17.0~13.3 Ma气候湿润,(g)13.3~9.5 Ma快速变干,(h)9.5~7.0 Ma进一步变干旱.影响柴达木盆地古‒新近纪气候变化的主要因素包括全球温度、副特提斯海、青藏高原构造隆升和东亚夏季风.
