中文拼音 [fēijūnyúnxínghé]
非均勻形核
英文
heterogeneous nucleation-
The fracture and spheroidization of cementite shows obvious anisotropy. there are two possible mechanism about spheroidization of cementite : the fracture cementite lamellae grows up non - uniformly and the fine spherical cementite particles grows up as the core
滲碳體的破碎和球化表現出明顯的各向異性。滲碳體的球化可能以兩種機制進行：破碎滲碳體片的非均勻長大和細小球狀滲碳體顆粒的形核長大。The fipwa based on electric integral equation ( efie ) is presented firstly, the green ’ s function expansion with sommerfeld identity ( based on bessel kernel ) is studied and the msdp for two cases is formulated. in order to improve the iteration property and avoid inner resonance, the combined field integral equation ( cfie ) fipwa is then constructed successfully
首先研究了基於電場積分方程的快速非均勻平面波演算法，對索末菲恆等式（基於貝塞爾積分核）展開的格林函數進行了深入研究，分兩種情形解決了修正最陡下降路徑的設計問題。By the analysis of coating ratio, oxidation ratio, micrograph and particle size of composite particle, it was found out that factors such as ph value, coating temperature, concentration of premonitory matter solution mainly affect the coating layer forming
通過包覆率、氧化失重率、形貌觀察、粒度和比表面積等分析發現，非均勻成核過程中溶液ph值、包覆溫度、覆層前驅物濃度等這幾個因素對石墨表面覆層形成有著重要影響。As foamer, had been made with buffer ph solution. in which the composition and reaction rale of combination process must be controlled. with scanning electron microscopy ( sem ), it is clear to observe that the shape of tih2 powder is changed from sharp after coated
試驗分析表明，以ph溶液作為緩沖沉澱液，通過控制反應成份濃度和速度，利用非均勻形核法可以實施al _ 2o _ 3包覆，其中溶液濃度和ph值對包覆效果影響最大，是保證非均勻形核包覆的關鍵。The thermodynamic conditions of decomposition of the foaming agent tih2, homogeneous and heterogeneous nucleation in high - temperature solid and liquid, growth and movement were achieved to demonstrate the trend of pore evolvement in this paper. moreover, according to the characteristics of in - situ gas foaming, the equations of the height change of foaming samples with heating time were primarily established to study the behavior of foams and to guild the experiment processes
另外，論文通過大量的熱力學分析，得出了發泡過程中發泡劑分解以及氣孔在固液態時的均勻形核和非均勻形核、氣孔的生長和運動等熱力學條件，揭示了氣孔演化的趨勢；論文還根據內生氣源發泡的特點，初步建立了高溫熔體中氣體發泡高度隨時間變化的方程，為進一步深入的研究發泡機理奠定了一定的基礎。分享友人
