write magnetic tape

With the number of dots in the screen becoming larger,the period of writing data into OLED is certainly becoming longer.

在協調數據的寫入和讀取方式上,提出了一種雙節拍模式的控制驅動方法,即外設RAM設立雙套模式,兩套RAM交替對數據進行讀寫操作,并且采用兩組驅動芯片分奇偶列同時向屏寫數據。

The relation between threshold voltage and writing time,programming voltage,tunnel area and floating area is simulated.

介紹了 EEPROM的電學模型 ,模擬分析了閾值電壓變化與寫入時間、寫入電壓、隧道孔面積、浮柵面積的關系 。

Experimentally,diffraction efficiency of photon crystal lattice was measured in different read-in angle.

測定了雙光束耦合時不同入射角度光子晶格的衍射效率,實驗曲線表明,衍射效率隨寫入角度(光子晶格周期)的變化也有極大值存在,并且與數值模擬所對應的角度是吻合的。

The examination,parameter read-in and the unit calibration of the combined meter board were implemented,suiting for kinds of digital instrument.

論述了系統設計中的幾個主要模塊,實現了組合儀表總成校驗、參數寫入及電路板檢測,該系統適合各類數字儀表檢測。
