    由於手寫板的引入，功能參數的增加，通過對這些參數的合理利用，開發出毛筆、鋼筆、鉛筆、濃淡筆、枯筆等一系列模擬真實筆的多種筆型功能。以這些功能為基礎，設計出功能豐富、更具表現力的電子白板系統，以增強視頻會議的實用性，使之更符合人們進行交流所需要的視覺、聽覺和手寫的自然習慣。
  2. The system is different from traditional silicon controlled dephasing method, such speedy modules as whole controlled electric and electronic equipment igbt and high frequency pwm controlling methods are employed, and the voltage of exchanging power supply of motor of beam pumping units can be controlled automatically, so there is no problem of power factor being decreased brought by silicon controlled phase single controlled, power factor in power net of beam pumping units " motor is enhanced really

    由於雙管齊下，電機電網側的功率因數得到了大大提高。與傳統的可控硅移相控制方式不同，本系統採用全控型電力電子器件igbt等快速模塊及高頻pwm控制方式，對抽油機電機的交流供電電壓進行自動控制，不存在可控硅相控角所帶來的功率因數變差的問題，真正提高了抽油機電網側的功率因數。
  3. The procedure is as follows : after the modeling of the electron quantum bit system and the control field, applying the lie - algebra, the control output is calculated by analogy with the classical optimal control method to achieve the target

    建立了該量子比特系統及其控制場的模型，藉助李群李代數，由經典最優控制的思想來獲得最優控制，從而實現了電子自旋量子系統任意量子態的最優制備。
  4. Since the concept of superlattice was proposed, vertical transport in superlattice has been investigated widely. the electric field domains and current self - oscillations which result from sequential resonant tunneling between different subbands of the superlattice are very significant phenomena. such kind of oscillation can be uesd to make tunable microwave oscillaors. in this thesis, low temperature transport problem, especially the formation of field domain and the condition of current self - oscillations in doped gaas / alas superlattice with weak coupling are investigated thoroughly and also by combining the macroscopic model with the microscopic one., the voltage - current characteristic and the current oscillation are simulated. the calculated result is nearly consistent with the experimental data

    由超晶格中子能級之間的順序多阱共振隧穿引起的電場疇及電流自維持振蕩現象是其中的一個非常有意義的分支，該現象可用來製作電壓調諧微波振蕩器。本論文對弱耦合摻雜gaaa alas超晶格中的縱向輸運特別是針對低溫下的場疇的形成和固定偏壓下電流自維持振蕩產生的條件進行了深入的探討，並結合宏觀模型和微觀模型對超晶格在時變電壓作用下的電壓-電流特性以及固定偏壓作用下的電流特性進行了模擬計算。
