  1. We find the chimeric protein in leaf epidermal cells, stomatal guard cell and root epidermal cell. actin filaments can be visualized clearly in guard cell, in guard cells of open stomata under light, actin filaments arrange reticulate randomly in cytoplasm. in guard cells of closed stomata under darkness, actin filaments arrange curly along the longitude of guard cell

    在葉片的表皮細胞、保衛細胞、根部的皮層細胞中有融合蛋白的表達,保衛細胞中微絲標記狀況良好,經光誘導處于開放態的氣孔的保衛細胞微絲呈網狀結構,在細胞內無規則分佈;經黑暗誘導處于關閉態的氣孔保衛細胞中微絲束沿保衛細胞縱軸排列,呈捲曲狀分佈。
  2. The steady - state errors of current closed loop system with pi current regulator in stationary and synchronous frames are compared using complex vectors. also, the corrector of rotor displacement control is studied by the root locus method

    應用復合矢量概念,對比了靜止坐標系和同步旋轉坐標系pi電流調節器組成電流閉環系統的穩態誤差,並用根軌跡法對轉子位移控制系統的校正環節進行了研究。
  3. This thesis presents an effective way to design pid controller through a combination of adverse deduce and genetic algorithm. the relationship between pid parameter and the root of the characteristic equation of the closed loop control system has been found out directly

    本文直接找出pid參數與閉環控制系統的特徵方程的根之間的關系,只要使特徵方程的根在z平面的單位圓內任意取值,然後再求出相應的pid參數,則閉環控制系統必然是穩定的。
  4. As long as the root of the characteristic equation is within the unit circle of z - plane and the corresponding pid parameter is got, the closed loop control system is sure to be stable. although the root of the characteristic equation can vary within the unit circle of z - plane, different value may affect the control property differently. therefore, it is better to optimize the root, here the optimizing method is carried out by genetic algorithm

    本文所採用的這種確定pid參數的方法,雖然可以使特徵方程的根在z平面的單位圓內任意取值,但各種取值情況對變風量空調系統的控製品質的影響卻不同,因此,要對各種特徵方程的根的取值情況進行尋優,本文採用遺傳演算法對特徵方程的根進行尋優,從而使控制器的參數得以優化。
  5. But the noise made when the door is closed is far beyond national correlative standards, and make serious noise pollution. the article put emphases on the mechanize of the electric control door through experiments on the spot and emulation of computer, then advance that the root of noise is that the design has defects. the safe close of the door is depended on the impulsion of door normal impacts

    本文密切關注了這種與大眾生活相關的研究課題,通過實測實驗和計算機系統模擬,重點研究了電控門工作的機理,提出了電控門噪音產生的根源是設計存在重大缺陷?電控門的安全閉合必須依靠門體正撞產生的沖擊力,並且沒有相關降噪措施,必然在使用造成巨大噪音的結果。
