    • The present disclosure relates to a hybrid working vehicle which determines the change of load by using a displacement of a flyweight or flyball in a governor, and controls a motor-generator according to the change of load, and a control method thereof. The hybrid working vehicle detects the change of load based on the displacement of the flyweight or flyball measured by a displacement measuring device, operates a motor-generator as a motor to supplement the power in a case where the load increases, and operates the motor-generator as an electric generator to collect energy in a case where the load decreases. In this way, revolution per minute (RPM) of a diesel engine may be detected rapidly and accurately based on the displacement of the flyweight or flyball without installing any complicated apparatus such as a torque measuring device which measures torque of a load, and accordingly controls the motor-generator so as to enhance the energy efficiency of the hybrid working vehicle and to improve the comfortable feeling of a driver.
    • 本公开涉及通过使用调速器中的飞重或飞球的位移来确定负载变化的混合动力车辆,并且根据负载的变化来控制电动发电机及其控制方法。 混合动力车辆基于由位移测量装置测量的飞重或飞球的位移来检测负载变化,在负载增加的情况下操作电动发电机作为电动机来补充功率, 发电机作为发电机,在负载减少的情况下收集能量。 以这种方式,可以基于飞重或飞球的位移快速且准确地检测柴油发动机的每分钟转数,而不需要安装任何复杂的装置,例如测量负载扭矩的扭矩测量装置,因此控制 电动发电机,以提高混合动力车辆的能量效率,提高驾驶员的舒适感。

    • A biodegradable polyester is formed by carrying out esterification and polycondensation with a carboxylic acid monomer group comprising at least one aliphatic dicarboxylic acid containing 2 to 14 carbon atoms and at least one aromatic or alicyclic carboxylic acid, and at least one glycol in the presence of a composite catalyst comprising a titanium compound, a zinc compound, an antimony compound and a phosphorous compound. The composite catalyst significantly improves the reaction rate of polyester polymerization as well as increases the production amounts of the polyester, as compared with conventional catalysts. The polyester is high in molecular weight, excellent in thermal and mechanical properties by virtue of the introduction of the aromatic or alicyclic carboxylic acid or its derivative, in addition to showing good biodegradability. This polyester can replace preexisting, expensive aliphatic polyesters.
    • 可生物降解的聚酯通过与包含至少一种含有2至14个碳原子的脂族二羧酸和至少一种芳族或脂环族羧酸的羧酸单体组和在至少一种二醇的存在下进行酯化和缩聚而形成 复合催化剂,其包含钛化合物,锌化合物,锑化合物和磷化合物。 与常规催化剂相比,复合催化剂显着提高聚酯聚合的反应速率以及增加聚酯的生产量。 除了显示出良好的生物降解性之外,聚酯具有高分子量,由于引入芳族或脂环族羧酸或其衍生物而具有优异的热和机械性能。 这种聚酯可以代替预先存在的昂贵的脂肪族聚酯。
