漏气率是磁流体真空动密封组件的关键技术指标。
The leak rate is the key specification of vacuum dynamic sealing with magnetic fluid.
结果表明：通过熔炼速度、漏气率、预真空等关键因素的严格控制，可大幅度提高大规格纯钛铸锭中氧元素的均匀性。
The results show that, through controlling the melting rate, leak pressure and pre-vacuum rigidly, the oxygen homogeneity can effectively improve.
