A. 大盤指數是什麼意思
大盤指數是指滬市的「上證綜合指數」和深市的「深證成份股指數」，屬於股票指數。
股市指數可以說是，就是由證券交易所或金融服務機構編制的、表明股票行市變動的一種供參考的數字。
如何能直觀地知曉當前各個股票市場的漲跌情況呢？通過觀察指數就可以。
股票指數的編排原理還是比較錯綜復雜的，我就不做過多的解釋了，點擊下方鏈接，教你快速看懂指數：新手小白必備的股市基礎知識大全
一、國內常見的指數有哪些？
會根據股票指數的編制方法及其性質來進行分類，股票指數大致分為這五種類型：規模指數、行業指數、主題指數、風格指數和策略指數。
在這當中，規模指數是最經常見到的，譬如大家都知道的「滬深300」指數，它說明的是在滬深市場中交易活躍，且代表性和流動性都很好的300家大型企業股票的整體情況。
另外，「上證50 」指數也是一個規模指數，其具體作用就是能夠表達出上海證券市場代表性好、規模大、流動性好的50隻股票的整體情況。
行業指數其實就是對於某一個行業的整體情況的一個整體表現。例如「滬深300醫葯」就屬於行業指數，代表滬深300指數樣本股中的17個醫葯衛生行業股票整體狀況，也對該行業公司股票整體表現作出了一個反映。
某一主題的整體情況是用主題指數作為代表的，就好比人工智慧、新能源汽車這些方面，這是有關聯的指數「科技龍頭」、「新能源車」等。

二、股票指數有什麼用？
根據前文內容可得，指數選取了市場中具有代表性的一些股票，所以，如果我們就可以通過指數比較迅速的獲得市場整體漲跌狀況的信息，那麼我們就能順勢看出市場熱度如何，甚至對於未來的走勢也可以預測一二。具體則可以點擊下面的鏈接，獲取專業報告，學習分析的思路：最新行業研報免費分享

B. Panasonic HDC-TM80GK 和SONY HDR-CX180E 高清攝像哪個好望高手指點
如果是動態像素的話，兩款機器都是1920×1080的，不過畢竟是攝像機，靜態像素就遠遠不如照相機好了，靜態索尼的高一些（我剛剛買）。防抖效果是松下的好，但畢竟索尼是大品牌，CCTV都採用它。個人建議購買索尼HDR-CX180E。我剛買完，效果還不錯！還有，索尼有什麼降噪、內置USB功能、高爾夫球模式等很多功能，做工也精細。
C. 截圖API函數
我寫過一個VB寫的截圖軟體,自定義矩形截取特定區域,需要的話把你的郵箱告訴我,我發源碼給你.
主要的API:
Public Const PM_REMOVE = &H1
' 滑鼠相關消息
Public Const WM_MOUSEFIRST = &H200
Public Const WM_MOUSELAST = &H209
Public Const WM_RBUTTONDOWN = &H204
Public Const WM_LBUTTONDOWN = &H201
Public Const WM_RBUTTONUP = &H205
Public Const WM_LBUTTONUP = &H202
Public Const WM_MOUSEMOVE = &H200
' BitBlt 函數常量
Public Const SRCCOPY = &HCC0020
Public Const SRCINVERT = &H660046
' PatBlt 函數常量
Public Const DINV = 3
Public Const DSTINVERT = &H550009
