A. 大盘指数是什么意思
大盘指数是指沪市的“上证综合指数”和深市的“深证成份股指数”，属于股票指数。
股市指数可以说是，就是由证券交易所或金融服务机构编制的、表明股票行市变动的一种供参考的数字。
如何能直观地知晓当前各个股票市场的涨跌情况呢？通过观察指数就可以。
股票指数的编排原理还是比较错综复杂的，我就不做过多的解释了，点击下方链接，教你快速看懂指数：新手小白必备的股市基础知识大全
一、国内常见的指数有哪些？
会根据股票指数的编制方法及其性质来进行分类，股票指数大致分为这五种类型：规模指数、行业指数、主题指数、风格指数和策略指数。
在这当中，规模指数是最经常见到的，譬如大家都知道的“沪深300”指数，它说明的是在沪深市场中交易活跃，且代表性和流动性都很好的300家大型企业股票的整体情况。
另外，“上证50 ”指数也是一个规模指数，其具体作用就是能够表达出上海证券市场代表性好、规模大、流动性好的50只股票的整体情况。
行业指数其实就是对于某一个行业的整体情况的一个整体表现。例如“沪深300医药”就属于行业指数，代表沪深300指数样本股中的17个医药卫生行业股票整体状况，也对该行业公司股票整体表现作出了一个反映。
某一主题的整体情况是用主题指数作为代表的，就好比人工智能、新能源汽车这些方面，这是有关联的指数“科技龙头”、“新能源车”等。

二、股票指数有什么用？
根据前文内容可得，指数选取了市场中具有代表性的一些股票，所以，如果我们就可以通过指数比较迅速的获得市场整体涨跌状况的信息，那么我们就能顺势看出市场热度如何，甚至对于未来的走势也可以预测一二。具体则可以点击下面的链接，获取专业报告，学习分析的思路：最新行业研报免费分享

B. Panasonic HDC-TM80GK 和SONY HDR-CX180E 高清摄像哪个好望高手指点
如果是动态像素的话，两款机器都是1920×1080的，不过毕竟是摄像机，静态像素就远远不如照相机好了，静态索尼的高一些（我刚刚买）。防抖效果是松下的好，但毕竟索尼是大品牌，CCTV都采用它。个人建议购买索尼HDR-CX180E。我刚买完，效果还不错！还有，索尼有什么降噪、内置USB功能、高尔夫球模式等很多功能，做工也精细。
