  1. The temperature rise at the center of a massive concrete wall is calculated by using the adiabatic rise of temperature and heat conduction equations of concrete based on the equivalent time, and considering effects of temperature on the hydration heat reaction ratio and creep characteristics of early - age concrete

    摘要基於等效時間的混凝土絕熱溫升、熱傳導方程,考慮溫度對早期混凝土水化熱化學反應速率和徐變特性的影響,計算了大體積混凝土墻中心的溫升。
  2. Furthermore, this dissertation also gives a comprehensive analysis and comparison to the torque ripple factor, torque - current ratio and other aspects for pseudo - sinusoidal emf bldcm drived by 120 conduction mode, 180 conduction mode and self - synchronous svpwm mode respectively. the simulation and the experimental results indicate that self - synchronous svpwm method is more effective for minimizing the torque ripple without any expense of the torque - current ratio when the crest width of the back - emf waveform is less than 107 electrical angles

    對準正弦波反電動勢無刷直流電動機在120導通方式、 180導通方式和自同步svpwm三種控制方式下的轉矩脈動系數、轉矩電流比等方面進行了全面的分析與比較,模擬研究和實驗結果表明,當反電動勢的平頂寬度小於107電角時,採用自同步svpwm控制方法可以在不損失轉矩電流比的基礎上,更有效地抑制電磁轉矩脈動。
  3. The n type carrier was provided by interstitial zn atom, and zn / o ratio and crystalline quality of zno thin film effeted its hall mobility. when zno thin film was annealed in the ar ambience, p conduction type was founded in the zno thin film which grew in oxygen enrichment condition. this might be excess oxygen in zno thin film entered interstitial position of crystal lattice ( oi ), and p type carrier was from oi

    在ar氣保護下,對富氧條件下生長的zno薄膜的退火后的霍爾測量中發現, zno薄膜呈現p型導電狀態,分析認為,這可能是由於富氧狀態下生長的zno薄膜中過量的o在ar氣保護下退火沒有逸出薄膜,反而進入了zno薄膜的間隙位置,成為正電中心,使zno薄膜呈現p型導電。
