-
Abstract : the reasonable distribution of mix bulk density and partical size on the transverse and lenghwise direction of sintering pallet, the relationship between segregation index and mix bulk density were discussed. the ways for improving mix bulk density, enhancing mix partical segregation, decreasing side wall effect and increasing bed surface flatness were proposed
文摘:論述了臺車上橫向、縱向混合料容積密度及粒度的合理分佈，偏析指數和混合料容積密度的關系，提出了改善臺車上混合料容積密度，加大混合料粒度偏析，降低邊緣效應及提高料面平整度的布料途徑。 -
The average partical size of bismuth ruthenate and pbo - b _ 2o _ 3 - sio _ 2 glass was researched. the smaller bismuth ruthenate partical is, sheet resistivity is lower and temperature coefficient of resistance ( tcr ) is more positive and the refiring change ratio is nearer to zero. the limit size of bismuth ruthenate partical is 0. 56 m
研究了各相粉體平均粒徑對膜層性能的影響，結果表明:釕酸鉍平均粒徑越小，膜層的方阻值越小，電阻溫度系數偏正，重燒變化率越接近零值，球磨工藝的極限平均粒徑為0 . 56 m 。 -
Ultrafine a - ahoa powder with average crystalline size of 27nm and spherical secondary partical shape of 40nm has been prepared by the method of adding dispersant before reaction. after discussing the agglomeration mechanism, the paper studies the way to eliminate the hard agglomeration. it thinks that main reasons to lead to agglomeration are larger specific surface area and high reactivity of nanopowder
認為導致團聚的主要原因是：納米粉體顆粒的表面有許多斷鍵，相互之間或與其它物質之間容易產生毛細管力、氫鍵、化學鍵等多種作用力，在採取措施消除團聚的過程中必須全方位考慮，實現全程式控制制。 -
The sheet structure of pvc was found in the rupture partical of pvc. the nanocrystalline pvc formed through jet - mill crashing. different crash condition had effect on particle morphology and melting point and crystallinity and particle size distribution
納米晶pvc是由氣流磨粉碎形成的，不同的粉碎條件對納米晶pvc的顆粒形態、熔點、結晶度、粒徑分佈形成不同的影響。 -
The results show that all of them have little different effect on the crystalline size of ultrafine powder of a - ahc ^, but they have greatly different effect on the secondary partical size. the azeotropic distillation is the most effective processing, it can prevent the formation of hard agglomerates and improve the sinter - ability of powder. the mechanism of drying stages preventing the formation of hard agglomerates has investigated
研究了三種不同的乾燥方法（直接乾燥法、酒精置換乾燥法和共沸蒸餾乾燥法）對粉體性能的影響。實驗表明三種乾燥方法對- al _ 2o _ 3粉體的一次粒徑的差別性影響不顯著，而對其二次粒徑的差別性影響則很顯著。 -
And the initial capacity is higher than that of doped - monoelement. in addition, a new modified calcination method was first put forward that is pretreatment + annealing. pretreatment makes it more easy to obtain pure phase and annealing makes the partical size distribution more even
03時產物有較好的綜合性能，比之單組元摻雜達到較佳性能時的摻雜量要減少，並且初容量升高，初容量為115m吶，第三次循環容量為114mah g 。 -
At the same time, a modified calcination method was first put forward, that is, after the first calcination, additional annealing was enforced. by the use of the thermal analysis, xrd, partical size, specific surface area and electrochemical measurement, the structure and performance of the product were studied, and the synthesis process was optimized by comparing structure and performance with one another
通過優化合成工藝，發現ph值在2 3之間、 paa與金屬離子的摩爾比為1 . 4 ： 1 、燒結溫度為550 、燒結時間在10h左右時所得產物有良好的結構和電化學性能。
