摘要：

New　TA(NIM)　System　used　to　produce　standard　Time　&Frequency　signal　was　set　in　T&F　lab　of　NIM(National　Institute　of　Metrology).　The　frequency　difference　data　past　year　between　NIM4　Fountain　clock　and　Hydrogen　maser　and　predicted　the　frequency　for　hydrogen　maser　of　next　week　by　liner　fitting　in　this　paper.　After　compare　of　prediction　and　real　frequency　difference　data,　it　finds　a　reasonable　method　which　could　predict　well　next　week　frequency　for　hydrogen　maser.　This　prediction　method　overcomes　the　limit　in　continuous　operation　of　NIM4　Fountain　clock　to　some　extent,　and　improves　the　continuity　and　stability　of　New　TA(NIM)　time　scale.
