MOSFET has higher working speed and smaller voltage and current than IGBT's. MOSFET has been selected for study the solid state switch technology working on higher repetition rate.
MOSFET的工作速度比IGBT高，耐压和电流比igbt小，本文采用MOSFET研究工作在更高频率下的固体开关技术。
Results showed that sugar removing rate decreases as solid concentration increases and that the higher the enzyme dosage, the larger is the sugar removing rate.
结果表明，随着固形物浓度的增加，除糖率逐渐降低；木聚糖酶用量越大，除糖率越高。
