緻密堆積
英文
dense packing-
The effects of main process factors such as feeding mode, reaction ph values, and ratio of ammonia and nickel ion, reaction time, agitation, reaction temperature and aging et al on the crystallization course and physical properties of nickel hydroxide were studied in detail. at last, we acquired the optimal preparation parameters, the spherical nickel hydroxide with high tap density and crystalloid degree, perfect flow ability were prepared
在研究加料方式，氨水的加入量，反應時間、體系ph值、反應溫度、攪拌、陳化等主要工藝條件對ni （ oh ） _ 2結晶過程和物理性能影響的基礎上，確定了較優的工藝參數，制備出了堆積密度和結晶緻密程度較高、流動性較好的球形ni （ oh ） _ 2 。The experimental data has been used to validate pdm and low temperature sintering mechanics. the advantage and disadvantage of pdm have been discussed also. for the first time, the pdm is used to study the low temperature sintering mechanics of uo _ 2, and the research results indicate : 1
3 、基於燒結頸長大速率與緻密化動力學方程得出，影響二氧化鈾低溫燒結的因素有原始粉末粒徑、粉末堆積方式、坯塊原始密度、燒結溫度、燒結時間、燒結氣氛等;粉末壓坯一定時，燒結溫度、燒結時間和燒結氣氛就成為控制低溫燒結的關鍵因素。Determined by dsc. whereafter, the surface micro - morphology of both sides of tini sma thin film deposited on glass was investigated by atomic force microscope ( afm ), and the difference of morphology between the two sides is observed. it has been shown that, in the growing surface of sputtered tini film, the trend of grain to accumulating along the normal direction like a column is clearly observed, and the grain is very loose which resulted in more microcavities, but in the surface facing to glass substrate, grain is so compact that there are hardly microcavities
通過濺射法，在玻璃襯底上淀積了tini薄膜，並在600進行了真空退火， dsc法測得其馬氏體逆相變峰值溫度為75 ，利用原子力顯微鏡，對玻璃基tini形狀記憶合金薄膜的襯底面與生長面進行了表面微觀形貌分析，發現：生長面晶粒呈現出沿薄膜法線方向柱狀堆積的趨勢，晶粒緻密性差，微孔洞多；而襯底面晶粒緻密，幾乎沒有微孔洞存在。Sem results show tin films appear compact and plane in different n2 partial pressure, and there is no big crystal grain appearance on the surface of tin films. tem and afm results tin films have the column structure, and the surfaces of the films are accumulated by crystal grain. in the second part of the thesis the effect of heat treatment processing on the optical properties and structure of the tin films is studied
Tem測試結果顯示，薄膜表面是由tin晶體顆粒堆積在一起，呈柱狀結構afm測試結果表明， tin薄膜呈柱狀結構；在氮氣分壓較小時， tin薄膜表面比較平整，顆粒細小；隨著氮氣分壓的增加， tin薄膜表面顆粒逐漸增大；相同氮氣分壓下，氬氣分壓較小時制備的tin薄膜較為緻密。Its dense metal membranes produce high purity hydrogen over a wide range of pressure and load
以緻密堆積金屬製成的薄膜可在大范圍的壓力與進料負荷下均可分離出燃料電池所需純度的氫氣。分享友人
