  • Furthermore , by integral method , all test data at different aging temperatures can be analyzed as an integration , so the prediction precision of storage life can be increased with the same specimens , or specimens can be saved in the same precision by this method
    而且,固體推進(jìn)劑貯存壽命整體預(yù)測(cè)方法能將各個(gè)老化溫度下的固體推進(jìn)劑試驗(yàn)數(shù)據(jù)作為一個(gè)整體進(jìn)行統(tǒng)計(jì)分析,具有更大的信息量,可以提高壽命預(yù)測(cè)精度或節(jié)省大量試樣。
  • A reliability experiment of thermal aging was carried out for the two types of joints , scanning electron microscopy , energy dispersive x - ray spectrometer and micro x - ray diffractomer were adopted to investigate the interfacial evolution behavior of joints , and kinetics model of imc formation was established . the results show that imc growth follows the parabolic law as a function of aging time at certain aging temperature , imc growth is more sensitive to the aging temperature than the aging time , the activation energy of cu - al imc growth is 97 . 1kj / mol and the major forming cu - al imc are cual2 and cu9al4 , the activation energy of au - al imc growth is 40 . 1kj / mol and the main au - al imc are au4al and au5al2 , with au2al and aual at the interfacial periphery of joints , the rate of cu - al imc growth is about 1000 times slower than that of au - al imc , and kirkendall voids and cracks are easily appeared during thermal aging in gold ball bonds while voids and cracks are absent in copper ball bonds even after aging at 200 for 2900 hours and 250 for 169 hours
    研究結(jié)果表明:金屬間化合物厚度與老化時(shí)間的關(guān)系符合拋物線法則,金屬間化合物的生長(zhǎng)對(duì)老化溫度比老化時(shí)間更加敏感; cu - al金屬間化合物生長(zhǎng)的激活能為97 . 1kj / mol ,老化后金屬間化合物呈層狀分布,主要相為cual2和cu9al4 ; au - al金屬間化合物生長(zhǎng)的激活能為40 . 1kj / mol ,主要相為au4al和au5al2 ,同時(shí)在界面周邊區(qū)域生成了au2al和aual ;老化過程中cu - al金屬間化合物生長(zhǎng)速率比au - al金屬間化合物生長(zhǎng)速率小103數(shù)量級(jí);金絲球鍵合點(diǎn)200老化96小時(shí)出現(xiàn)了明顯的kirkendall空洞和裂紋,但銅絲球鍵合點(diǎn)200老化2900小時(shí)和250老化169小時(shí)都沒有形成空洞和裂紋。
  • During the preparation process of the solid solution , a series of effect conditions were discussed such as ph value , si / h2o , the content of ligant , the surface active agent , the aging temperature , the drying means , the drier gel calcine and their effects on the gel quality , the process of sol - gel , the granular of powder and the density of the pellets , from which the best reaction condition was found
    在制備過程中系統(tǒng)地研究了各種反應(yīng)條件如ph值、 sal ; o 、絡(luò)合劑的添加量、老化溫度、干燥方式、干凝膠的鍛燒方式等對(duì)溶膠“的質(zhì)量、溶膠凝膠過程、粉體粒度及燒結(jié)體密度等的影響,確定了最佳反應(yīng)條件:三、以li 。石i 。 。
