明天又要开盘，说回行情，先从周五的尾盘开始讲。 国家队又一次在收盘前出手护盘，比较明显的标的还是华夏沪深300etf（代码510330），分时线很明显的看到最后10分钟买了将近40亿，本来靠着这笔资 金可以把上证指数从-0.3%抬到红盘，但这次遇到了一些小意外，最后3分钟突然汹涌而出大量卖盘，把大盘又砸回去了一些，导致最终收盘的时候上证指 数绿了，下跌0.11%。 再细节一点，就是关注510330的交易量，突然来了连续的大额买单，就跟着一起买，快收盘了赶紧抛。这么干的人多了，波动就会放大，包括最后三分钟 的回落幅度也比以前大，因为这种搞偷鸡的资金不愿意持仓过夜去承担额外的风险。 总之上证指数的8连涨在一片混乱中被终止，那跌了有什么不良后果吗？其实也没有，就是宣传上不好说贸易战之后中国股市每天都涨了，这种不必要的 包袱早点卸下了也好。 你们看周五的成交量，都缩到9100亿，没眼看了，这种僵尸行情真就是浪费时间，表面上每天尾盘拉升mini涨，其实市场并不认可指数的有效性，纷纷离 场观望。总不能贸易战一天没打完，大盘就一直立正罚站吧。 反正我是无所谓的，现在年化贴水率挺高，哪怕一直僵硬到年底也不白给，就这么耗着好了 ...

卫星技术的演进 即便如此， 高盛研究部认为LEO卫星非常有潜力成为主流技术，对传统电信公司带来负面和正面影响 。在早期阶段，LEO卫星将可以 增补偏远 地区的宽带 ，与农村地区的传统宽带形成竞争。从长远来看， 卫星技术可能会纳入移动网络中 ，通过卫星和电信运营商之间的合作实现通信系 统无缝连接。 卫星发射的成本 由于所处轨道高度较低，LEO卫星的覆盖范围亦较窄。此外，为了支持相当数量的人口能够同时使用LEO卫星通信， 需要更多的卫星来确保每个 用户都有足够的速度和带宽 。如果一颗卫星提供每秒960吉比特的带宽，并以大约每秒100兆比特的速度传输数据，则需要大约46万颗卫星才能覆 盖世界一半的人口。 发射的成本也可能很高 ：每公斤卫星有效载荷或将高达12,000美元。与地面传输系统相比，卫星可能有更长的延迟或通信速度的滞后。LEO 卫星的寿命较短，会产生大量的太空碎片，需要 积极的碎片管理 。 高盛大中华区科技研究主管 张博凯(Allen Chang) 近期发布研报， 预测未来五年内全球各地将发射多达70,000颗低轨道 (Low Earth Orbit, LEO) 卫星 。这些卫星通常位于距地球100-1,2 ...
