其次,通過對現場、試驗場電連接器的失效情況進行統計和分析,總結出電連接器的四種主要失效模式:電接觸失效、絕緣失效、機械連接失效和其他失效,並對電連接器進行了故障樹分析,指出電接觸失效是電連接器失效的主要形式,而在正常的工作條件下,造成電接觸失效,即決定電連接器工作壽命的主要原因是氧化膜層的生長、接觸對磨損以及磨損腐蝕物的堆積,而影響氧化膜層的生長、接觸對磨損以及磨損腐蝕物堆積的主要因素是環境振動和溫度應力,為電連接器進行失效機理分析奠定了基礎。Typical temperature is 800 - 1000 in cvd diamond process, while the high temperature limits its application in optical window and coating such as gaas, zns etc. low temperature can not only make diamond crystal nucleus finer, reduce surface roughness of diamond films and lessen light dispersion, but also eliminate thermal stress
化學氣相沉積金剛石膜過程中,襯底的典型溫度為800 1000 ,這么高的溫度限制了其作為gaas 、 zns等低熔點光學材料窗口和塗層的應用。低溫沉積金剛石膜不僅可以使晶粒細化,降低表面粗糙度,減小光的散射作用,而且可以消除熱應力。It can be concluded that the performance differences between the plate membrane and the hollow fiber membrane can be attribute to difference of the stresses in the membranes when they were under pressure and the difference of the strain caused in the membrane, besides the possible reason that the surface curvature difference between a plate substrate and a hollow fiber one may cause structure difference in the dense functional layer when coating. the stresses in a hollow fiber composite membrane under an outside pressure are quite different from that in a plate one in that they exert on the hollow fiber in both the radial and circular directions, and the compress strain of the hollow fiber is thus much more complex, which may cause the top layer crinkle and a decreased salt rejection
分析認為造成平板復合膜( )和中空纖維復合膜( )性能差異的主要原因,除了平板基膜與中空纖維基膜因表面曲率不同可能引起在塗覆時形成的緻密功能層結構上的差異之外,由於中空纖維膜受外壓時,膜內部承受的應力形式與平板膜不同,會同時在徑向(膜厚度方向)和環向(膜面內方向)兩個方向產生壓應力,因此,所發生的形變也較為復雜,可能造成表面復合層的起皺或脫落,引起脫鹽率下降。The chemical composition, micro - structure and optical properties and its application of tio2 thin films deposited on k9 glass by using reactive electron - beam evaporation ( reb ) are studied through sem, tem, xps, xrd, spectroscopic ellipsometry ( se ) and uv - vis spectrophotometer in the dissertation, and the progresses of nucleation and growth of thin film are discussed from the point of view of dynamics and thermodynamics so that a structure model of tio _ ( 2 ) thin film is brought forward
