  1. In the study, six different ecotype varieties of common wheat and f1 derived from 6 6 complete diallel crossing system were selected for the research on the characteristics and heterosis of spike differentiation. the results showed that heterosis existed in most key spike differentiation phases and varied with different ecotype varieties. heterosis of spike differentiation was positively correlated with heterosis of hybrid yield. finally, the author concluded that it was the best way to produce strong heterosis combination by selecting the mode of “ spring wheat winter wheat ” in huanghuai winter wheat region

    對6個不同生態類型小麥品種及其完全雙列雜交f1幼穗分化特點和穗分化雜種優勢的研究表明，雜種幼穗分化各主要時期普遍存在雜種優勢；不同生態類型組配方式的雜種穗分化優勢不同；穗分化雜種優勢與產量雜種優勢具有一定相關關系；黃淮麥區雜交小麥最佳生態組配方式為春性品種冬性品種。

  3. Reactive power are calculated using the new algorithm. on the basis of analyzing different kinds of control strategies of var compensation, the paper applies the criterion of voltage and var to control switching and illustrates a improved mode of switching capacitor which can prevent the switched - capacitor from the impacting of instantaneous rush currents by means of zero - crossing triggering of scr components, and can realize auto - tracking var and auto - switching shunt capacitor bank. initial operating parameters are stored in information flash memory of the mcu using flash self - programming technique in order to decrease complexity of the circuit and improve stability

    高壓智能無功補償控制器以flash型16位單片機msp430f149為控制核心，採用了一種相角實時測量的新演算法，並在此基礎上計算出了功率因數、有功和無功，減少了運算量提高了精度；在分析了各種無功補償控制策略的基礎上，以母線電壓和無功功率復合判據控制投切，並提出一種改進的電容器投切方式? ?暫態投切控制晶閘管過零觸發，避免了電容器投切時的電流沖擊；穩態運行時接觸器替代晶閘管，實現無功補償的自動跟蹤和電容器的自動投切，解決了投切時的暫態電流沖擊和穩態時可靠運行的難題；控制器的原始運行參數採用flash自編程技術，將其保存在msp430f149片內的信息flash中，簡化了硬體電路，大大提高了系統的可靠性。
  4. The function of instructional research is that : ( 1 ) it rea lizes a communication crossing time, space and people, ( 2 ) it promotes the professional development of teachers, ( 3 ) it provides abundant, dynamic instructional resource bank, ( 4 ) it establishes a dynamic, web - class. the organizational and managing way of virtual instructional research is discussed in three aspects : the managing mode in technology and resource, the managing mode in human resource and the managing mode in organization

    虛擬教研活動的組織管理方式： （ 1 ）對一線教師組織的教研活動而言，其組織管理方式的特點是，由教師個體的自我管理，逐步發展到教師自發組建的團隊管理； （ 2 ）對依託教研部門開展的虛擬教研活動而言，其組織管理方式的特點是分各層級進行管理，即，由上下級教研部門相互配合開展教師虛擬教研活動。
