The hardware mainly includes light , image sensor , image collector . the improvement of hardware , which can realize gate control of the 9 cmos by the two - way communication with the computer , and can improve the mtf measurement accuracy of the whole field of view , is introduced in detail 硬件部分主要包括光源、圖像傳感器、圖像采集設備等,并詳細介紹了系統硬件的完善部分,即通過與計算機的雙向通信,實現了9個cmos的選通控制,從而提高全視場mtf的測量精度。
Give education at traditional area relatively , long - range education has a few such striking features : during whole study , teachers and students allows permanent depart ; educational orgnaization or organization pass study data and support to serve two respects to bring to bear on to the student ' s study influence ; use all sorts of technologies to media contacts teachers and students and bear the weight of curricular content ; provide two - way communication communication ; during whole study , do not set study collective permanently definitely , the student basically is with individual chemistry be used to is given priority to 相對于傳統的面授教育,遠程教育有這樣幾個顯著的特征:在整個學習期間,師生準永久性地分離;教育機構或組織通過學習材料和支持服務兩方面對學生的學習施加影響;利用各種技術媒體聯系師生并承載課程內容;提供雙向通信交流;在整個學習期間,準永久性地不設學習集體,學生主要是以個別化學習為主。
The thesis deeply analyses and studies the issue of how to communication between com component and its clients in com model . component and its clients is communicated by interface . com mechanism shields its rock - bottom realization , provides a application communication platform , and realizes the two - way communication of component and its clients 本文主要針對com組件模型中客戶與組件間如何通信這個問題進行了深入分析與研究,兩者間以接口的形式通信,其通信機制屏蔽了底層的網絡通信協議,提供了一個應用級的通信平臺,可以很好的完成客戶與com組件間的雙向通信。
