隨濃度增加，大部分亞穩區合金沉澱非經典形核長大的特徵增強，有序相臨界晶核序參數分佈曲線降低，且分佈更加平緩，沉澱序列為：過飽和固溶體非化學計量比有序相化學計量比相長大，非化學計量比有序相併非熱力學意義上的亞穩相，研究工作明確了這一點。Following these two examples of two and three phases, regarding ternary and quarternary metallic melts involving eutectic as melts consisting of three and four non - homogeneuos solutions correspondingly, and using thermo - dynamic parameters of binary metallic melts involving eutectic, calculating models of mass action concentrations for ternary symmetrical melts formed from similar metastable compounds, ternary unsymmetrical melts formed from unsimilar metastable compounds and quarternary metallic melts involving eutectic have been formulated
仿照這兩個二、三相熔體的例子，將含共晶體三、四元金屬熔體看作由3 ， 4個溶液組成的非均相熔體，並利用含共晶體二元金屬熔體的有關熱力學參數，針對由同類亞穩態化合物組成的對稱型三元系、不同類型亞穩態化合物組成的非對稱型三元系及四元系含共晶體金屬熔體，制定了相應的作用濃度計算模型。Catalysts were prepared by impregnation reduction, thermal reduction, advanced thermal reduction and sol - gel methods from these metals. electrochemistry measurements, xrd, tem were used to test these catalysts. the results showed that these metals have some electrocatalysis activities towards hydrogen oxidation reaction
本文選擇了w 、 mo 、 co等金屬，採用浸漬還原法、熱還原法、改進的熱還原法以及溶膠凝膠法分別制備了這幾種金屬的碳載催化劑，對制備出的非貴金屬催化劑進行了電化學測試、 x -射線衍射（ x - raydiffraction ， xrd ） 、透射電子顯微鏡（ transmissionelectronmicroscopy ， tem ）等測試，研究結果表明:這些非貴金屬在硫酸體系中對氫氣的氧化反應均有一定的催化活性。In addition, the effective combination technologies of ultrasonic, microwave, alternating current deposition, supercritical fluid drying with traditional liquid methods is the most promising one to prepare high purity, small size and well - proportioned dispersing nano - particles
而超聲技術、微波輻射技術、交流電沉積技術、超臨界流體乾燥技術、非水溶劑水熱技術等新技術與傳統液相法的有機結合，是制備高純度、小粒徑、均勻分散的金屬氧化物納米粉體的最有前途的方法。By using x - ray diffraction ( xrd ), scanning electron microscopy ( sem ), transmission electron microscopy ( tem ), differential scanning calorimeter ( dsc ) and optical microscopy, mechanical activation is investigated. and during the study, two new innovative processes or thoughts, " dual activation reactive milling " and " in situ synthesis in salt bath activated by ma " has been presented for the synthesis of nanometer - sized powder. the phase transformation and oxidation control of cu - cr system during ma is also investigated
