Gas - filled shock absorber injected with pure n2 , which not only keeps stability of damping force , but also reduce aerification and foaming , meanwhile , extend the effective life 氣壓式內充入純氮氣,不僅可保持阻尼的穩定性,還可減少油液汽化及泡沫化,延長產品有效壽命。
Sg 10 series transformer is harmless to environment , it is disassembled easily when useful life is end , the conduct material and core can be recycled , when protect environment well 對環境無害。當該種變壓器的有效壽命結束時,可方便地對其進行拆卸,并將導電材料連同鐵心一起回收,真正做到環保。
Radial usually adopts wind axis with grease lubrication , within its longevity , need not use lubrication , can collocate constant lubricating cap according to requirements and adopt thin oil to lubricate 軸承通常采用油脂潤滑的流動軸承,有效壽命期內無需添加潤滑脂,并可根據要求配置油位恒定的油杯,采用稀油潤滑。
But the life time of krf laser medium is only 2 ns while the pump time of e - beam pump krf laser is over 100 ns . when a 1 ps ultrashort pulse amplified by krf laser amplifier most pump energy is waste . technology of multi pulse amplify can solve this problem Krf激光器的工作介質是非儲能介質,上能態有效壽命約為2 - 3ns ,而電子束的泵浦時間一般為上百ns ,放大超短脈沖激光時絕大部分上能態的儲能沒有被利用。
At the base of getting a great deal of structure corrode damage data and through statistic fitting method , discovered the rule between outboard wing corroded depth and lifespan at different airport . then we can calculate the inoxidizing coating lifespan , basal body corroding expansion lifespan and first repair time 在獲得使用中結構腐蝕損傷的大量數據的基礎上,通過統計擬合的方法,取得不同機場飛機外翼長桁腐蝕深度與日歷壽命的統計規律的基礎上,進而可以求得防護層的有效壽命、基體腐蝕擴展壽命。
With this understanding , this paper chooses the longitudinal strength of hull girder as the disabled mode , by the calculation of fpso , predicts the ultimate strength and effective lifetime of the hull . expected results of examples are obtained , which provide the analysis data for the further risk assessment 在此前提下,本文選擇了船體梁縱向強度失效模式,通過fpso實船計算,分析消化了理想單元法程序軟件,預報了船舶極限強度和安全有效壽命期,并用一階二次矩方法對完整受損船體的結構安全性進行了可靠性的評估,取得了預想的結果,為進一步實施綜合安全評估提供了分析數據。
