9299百瑞彩票液压技术是涉及液体流动和液体压力规律的科学技术。近几十年来.液压技术发展非常快。广泛应用于工业、农业和国防等各个部门。如机械制造业、起重设备、矿山机械、工程机械、农业机械以及化工机械;又如军舰上的舵机、雷达扫描设备、坦克、火炮、飞机、导弹等都采用了液压技术。特别是在机床行业中，由于采用液压传动可以实现无级变速、自动化和在往复运动中实现频紧的换向等，所以它的应用正在不断地扩大和完善。

Hydraulic technology is a scientific technology involving the law of liquid flow and pressure. In recent decades, hydraulic technology has developed very fast. Widely used in industry, agriculture and national defense and other departments. Such as machinery manufacturing, lifting equipment, mining machinery, construction machinery, agricultural machinery and chemical machinery; and such as warship steering gear, radar scanning equipment, tanks, artillery, aircraft, missiles and so on, all use hydraulic technology. Especially in the machine tool industry, because the use of hydraulic transmission can achieve stepless speed change, automation and frequency-tight commutation in reciprocating motion, so its application is constantly expanding and improving.
