  1. There are five parts are as follows : in part one, the concept of switching function is introduced first to establish the nonlinear mathematical model of the induction motor variable frequency speed adjustment system which is fed by a sine pulse width modulated ( spwm ) inverter and takes the effect of the main magnetic circuit saturation into consideration, then the low frequency oscillation of the system is simulated according to the model. next, from the view point of energy conversion of the inverter - induction system, a criterion for the low frequency oscillation is proposed to determine whether the system is in low frequency oscillation which is judged by whether the interval of the negative current component of the inverter input current is more than 1 / fc ( fc is the carrier wave frequency of the inverter ) or not

    首先引入開關函數概念，建立了正弦脈寬調制（ spwm ）逆變器供電異步電動機，考慮主磁路飽和時的變頻調速系統整體數學模型，模擬系統的低頻振蕩；其次從逆變器-異步電動機系統能量轉換角度出發，提出通過檢測逆變器輸入電流中負電流的間隔時間是否大於1 / f _ c （ f _ c為逆變器載波頻率）來判定系統是否出現低頻振蕩；最後的實驗結果驗證了系統低頻振蕩建模和判據的實用性和正確性。
  2. This d format can show the range of the data intuitively and express the real time data, which improves the speed and precision of svpwm arithmetic greatly. the ratio of carrier wave is increased and the blend of current is reduced, as a result the performance of the system is ameliorated. this thesis project has finished the debugging of the ac motor control system, and the result shows that hardware and software of the designed system is in reason

    在實現svpwm演算法的匯編程序中採用了一種新型的d定標法對標幺化的數值進行定標，這種d定標法能直觀的表示數值的大小范圍，可以實時的對數值進行定標，提高了svpwm演算法執行的精度和速度，增加了逆變器的載波比，減少了電流諧波，因而改善了交流變頻調速系統的性能。
  3. The gr series metal carrier catalyst, gwmc series motorcycle exhaust catalyst and gcp series motor exhaust muffler were appraised as high - tech products

    Gr系列金屬載體催化劑gwmc系列摩托車排氣凈化器gcp系列汽車排氣凈化消聲器被評為高新技術產品。
  4. We abide by the safety regulations set forth by the u. s. department of transportation for the motor carrier

    我們的司機會絕對遵守交通局訂立的交通規則保證行車安全。
  5. We have built the fist auto - production line of our country, which can produce 1, 000, 000 mental carrier catalysts per year. and built the half - auto production line that able to manufacture 300, 000 litre pottery beehive catalyst annually. catalyst product are used in motor exhaust gas control and petroleum chemic industry and environmental industry. any other business

    請問： 1 .貴公司產品用在摩托車上的工作原理？以及控制閥在什麼時候起作用？ 2 .控制閥上的負壓介面應該接到什麼地方？
