Standard practices for resistance of adhesives to cyclic laboratory aging conditions 膠粘劑耐周期性實驗室老化條件的標準試驗方法
The physical mechanical performance under the aging condition of 250 was superior to the normal formula of fluorubber carbon black 250老化條件下物理機械性能優于標準氟橡膠炭黑配方。
2 interlaboratory comparisons are valid only when all laboratories use the same design of fluorescent uv device , lamp , and exposure conditions 只有當所有實驗室都采用同樣設計的紫外熒光設備、燈和老化條件時,實驗室間的比較才是有效的。
Iso 4618 - 1 , 2 : 1984 , “ paint and varnish ? vocabulary , ” part 1 : general terms ; part 2 : terminology relating to initial defects and to undesirable changes in films during ageing 1984 “涂料、清漆?詞匯”部分1 :總則;部分2 :最初缺陷和在老化條件下,漆膜不合適變化的術語“ 。
The optimal aging conditions for the sensors investigated are : u 200 mv , f1 khz , t24 - 48 h , rh 81 - 87 % , t 3 80c ii the sensing mechanism of the humidity sensors has been explored by means of complex impedance analysis 合適的老化條件為:施加電壓200mv , 1khz , 24 48h , 38 , 81 87 rh 。采用復阻抗譜分析法,研究元件感濕機理,認為napss濕敏元件感濕機理為離子導電,其電導隨濕度的變化可由改進的onsager方程描述。
