  1. Experimental result shows that cavitation can destroy metal cyanogen preparation and chemical property of bearing cyanide wastewater is changed ; it intensify the fiber ' s adsorption progress and reduce the time of adsorption equilibrium, the general cyanide adsorption rate is increased 5 % or so, but it strength the different effect on different metal - cyanide negative ions ; strengthen effect of copper cyanide complex is stronger than zinc and iron cyanide complex, so ultrasonic wave may strength the fiber ' s adsorption processes

    實驗結果表明，功率超聲的空化作用能破壞金屬氰配合物鍵，從而改變含氰廢水的化學性質，另外也可縮短吸附平衡時間，強化纖維的吸附過程，使總氰的吸附率可提高5 %左右；功率超聲對不同金屬氰配合物離子的強化效果是不同的，對銅氰絡離子的強化效果要強于鐵氰、鋅氰絡離子，所以功率超聲可以強化纖維的吸附過程。
  2. Microstructural change and thermal shock performance of metal / ceramic graded thermal barrier coatings in thermal shock experiments were studied by scanning electron microscope and energy - dispersive spectrometry. the results showed : 1 ) metal microstructure kept intact while ceramic microstructure had been destroyed ; 2 ) thermal shock performance of coatings was interrelated with its function to relax residual stresses, therefore thermal shock performance of gradient thermal barrier coatings was better than that of terraced thermal barrier coatings ; 3 ) thermal shock performance was concerned with metal content in metal / ceramic thermal barrier coatings, which would be improved when metal content was increased

    利用掃描電子顯微鏡和能譜成分分析技術研究了金屬/陶瓷梯度熱障塗層在熱震過程中的顯微組織變化及其抗熱震性能.結果表明： 1 ）金屬顯微組織保持完好，陶瓷顯微組織有明顯的破壞； 2 ）塗層抗熱震性能與其熱應力緩和功能密切相關，梯度熱障塗層比階梯熱障塗層具有更高的抗熱震性能； 3 ）金屬/陶瓷熱障塗層抗熱震性能與其中金屬相含量有關，金屬相含量增加可改善塗層抗熱震性能
  3. 16mnr and 45 # steel are taken as examples. the obtained results have been applied to analyze the safety of operation pressure and rationality of design of a kind of engineering structure - a flange joint of hemispherical head to cylindrical shell. try to seek a sort of new method to assessment the capability of structure to load beyond the traditional method which regards stress and strain as main parameters

    本文以45 ~ #調質鋼和壓力容器常用鋼材16mnr為研究對象，對金屬材料韌性斷裂的斷裂模式進行細觀機理上的研究，進而分析一種工程結構? ?採用與筒體厚度不同的半球形封頭的壓力容器的筒體連接結構? ?的靜載變形特點和破壞形式，嘗試在以應力應變為主要參數的傳統方法之外，尋求一種新的結構承載能力分析的方法。
  4. The results at normal temperature have shown that klc of high polymer bonded explosive are very low comparing to metals and some high polymer materials, thus the ability of pbxs to resist crack expanding is very poor, and once some cracks occur inner a structural part of pbxs, the structure will fail very soon and easily. so in the process of machining and production, cracks should be avoided carefully in pbxs parts. some important laws about klc of the three typical pbxs above changes with temperature have been obtained as follows : a

    對三種具有代表性的高聚物粘結炸藥j1 、 j2和j3在常溫下的平面應變斷裂韌度進行了測試與研究，研究結果表明：相對于金屬及某些高分子材料而言，高聚物粘結炸藥的k _ （ ic ）值很低，即高聚物粘結炸藥的抗裂紋擴展能力是極差的，一旦炸藥構件中產生了裂紋，炸藥構件將極易破壞，因此，在高聚物粘結炸藥構件的生產及加工過程中，應避免裂紋的產生。
