氦泄漏试验作为一种致密性试验，它的检漏灵敏度远远超过了气密性试验和氨渗漏等试验方法。
As a seal test, sensitivity of helium leak test is higher than other test methods as gas seal and NH_3 leak test.
选择合理的氦泄漏试验方案，可做到既能检漏又能及时发现漏点，有效地保证钛制容器安全性和可靠性。
If appropriate helium leak test plan is selected, it will be of benefit to improving detectability and effectively secure titanium vessel safety and reliability.
