漏失試驗 的英文怎麼說
中文拼音 [lóushīshìyàn]
漏失試驗
英文
leakage test-
By physical and chemical testing and comprehensive analysis, it is suggest that deposited sands and rubber relics lead to local clogging of the pipe, so vortex around the clog lead to erosion abrasion
通過理化試驗和綜合分析后認為,海水中沉積的泥砂和管內橡膠殘片集結成一體,對傳熱管形成局部阻塞,水流在阻塞物周圍產生渦流,發生沖蝕磨損,造成鈦管泄漏失效。By compared with the simulation results and the experiment results, we come to the conclusions that : ( 1 ) circuit with assistant network can widen soft - switching extent in lagging arm, reduces duty - cycle loss on the secondary, diminishes switching dissipation of inverter spot - welding power source. ( 2 ) the range of resonant capacitor, the important factor to soft - switching process, not only affects zero - voltage turn - off of power switches, but also affects the range of zero - voltage turn - on of power switches. so resonant capacitors must be considered according to many aspects ; ( 3 ) it easily fulfils soft - switching condition in lagging arm as leakage inductance of power transformer increases, but bigger leakage inductance of power transformer increases opening dissipation of transformer and decreases efficiency of soft - switching inverter power source
通過模擬結果與軟開關點焊逆變器試驗結果的對比分析,得到了如下主要結論:採用輔助網路可以完全拓寬全橋軟開關逆變器的滯后橋臂軟開關范圍,減小了次級占空比丟失,降低了逆變電阻點焊電源的開關損耗;諧振電容是影響軟開關工作狀態的重要因素,其大小不僅影響開關管的零電壓關斷,同時也影響開關管的零電壓開通范圍,因此,諧振電容應該綜合考慮;功率變壓器漏感越大,越容易滿足滯后橋臂的軟開關條件,但是大的漏感也使變壓器的通態損耗增加,降低了軟開關逆變器的效率。Fire hazard testing - part 5 - 3 : corrosion damage effects of fire effluent ; leakage - current and metal - loss test method
著火危險試驗.第5 - 3部分:燃燒廢氣的腐蝕破壞效應.漏泄電流和金屬損失試驗方法According to the sample theory, applied the time terminated test plan, the reliability compliance test plan was brought forward. the reliability compliance test plan was divided into two parts, residual current protection test and operation reliability test. in this paper, the test plan, the failure criterion and the program of reliability test were introduced
