求翻譯：(1) Since PH-2201 and DV-2201 is operated at high temperature and vacuum,hot bolting by heating should be done before start-up.vacuum test should be done by starting the vacuum pump and leakage is checked.是什么意思？ 待解決

（1）自PH - 2201，DV - 2201是在高溫和真空，加熱螺栓熱的操作應該做啟動up.vacuum測試前應啟動真空泵和泄漏檢查。

(1)自 PH -2201和 dv -2201經營是在高溫和真空冷熱水加熱以前要做的螺栓開辦。真空測試工作應由開始的真空泵和滲漏是檢查。

(1)從PH-2201和DV-2201被管理在高溫度和真空，熱閂上由熱化應該完成，在開始up.vacuum測試應該由發動真空泵完成之前，并且漏出被檢查。

（1） 由于 PH-2201年和 DV-2201年操作在高溫和真空，加熱的熱錨應完成之前應該通過啟動真空泵開始 up.vacuum 測試和檢查泄漏。
