球團粒度 的英文怎麼說
中文拼音 [qiútuánlìdù]
球團粒度
英文
pellet size-
After the vacuum dry and the sphere mill, the level of agglomeration is low, the particle size is very small, spherical and the nanometer stannic dioxide powder with the aspects of good scattered nature is achieved
經真空乾燥和球磨粉碎后得到團聚程度低，粒度細小均勻，達到納米水平並具有較好分散性的球形二氧化錫粉體。This edta route has several remarkable advantages in comparison with other method. because of the greater ability of edta anions to chelate metal cations, and forming very stable and soluble complexes, all of the starting materials are mixed at the molecular or atoms level in a solution, it is easy to control the composition and a high degree of homogeneity is achievable
傳統的合成方法是高溫固相反應，由於灼燒溫度高、灼燒時間長，形成硬團聚體，產物粒徑較大，一般為m級，需進行球磨粉碎以減少其粒徑，很難制得均相、均一粒度分佈的氧化物粉體，在研磨過程中容易引入雜質且晶形破壞使得發光亮度減小。In the system of the online measuring of pellets diameters, the disturbed noises during the process of collecting pellets images are mainly impulse noise and white noise
摘要在球團礦粒度在線檢測系統中，球團圖像採集過程的干擾噪聲主要是脈沖噪聲和白噪聲。Abstract : the crystal structures obtained by static solidification and vibration solidification were compared. it was showed that, in the case of vibration solidification, the orientation growth of the columnar crystal was not obvious, the equiaxial crystal appeared more early. the grains of both types of crystals were quite fine, hardness in the full section was relatively high, and the hardness distribution was uniform. in the former case, the solute segregation in dendritical austenite more severe, and there were lumps of distortion inclusion
文摘:對球鐵金屬型靜凝固與振動凝固的結晶組織對比表明：後者柱狀晶方向性生長較弱，等軸晶出現較早，且兩者的晶粒均較細，全斷面硬度較高且分佈均勻；前者枝晶奧氏體內溶質偏析大，有畸變夾雜團塊。We consider : ( a ) boron particles agglomerated with technology in wet condition are high spherical, small and well - proportioned, ( b ) the technology with dry condition is simpleness and the radius of boron particles are big. 3
研究認為： （ 1 ）濕法聚團技術制得的聚團硼真球度高，粒徑均勻且粒徑較小： （ 2 ）干法聚團工藝簡單，制得的聚團硼粒徑較大。Under the condition of 1000 ~ 1200, study the effect of the carbon - bearing pellet strengths and metallization rate with different iron ore concentrate size, matching carbon ratio ( carbon oxygen mol ratio ), kind of additive and reduction temperature
摘要在1000 ~ 1200條件下研究了不同的礦粉粒度、配碳比、粘結劑、還原溫度等對含碳球團強度及金屬化率的影響。The samples were characterized contrastively by sem, tem, saed, positron annihilate and the different mechanism for two methods were preliminarily discussed. the experimental results showed that nano - cuo prepared by sol - gel method was spherical, which was agglomerated badly and can aging easily. however, nano - cuo prepared by pressure - hydrothermal method has loose and thin - piece appearance structure
結果表明，溶膠-凝膠法制得的氧化銅粉末呈類球形，團聚嚴重，易老化；而壓力-熱液法制得的氧化銅具有疏鬆的、薄片狀的外觀結構，粒子厚度約為20nm ，分散性較好、抗老化能力強；壓力-熱液法制備的氧化銅比溶膠-凝膠法制備的氧化銅缺陷濃度小。分享友人
