玻璃狀固體 的英文怎麼說
中文拼音 [bōlízhuànggùtǐ]
玻璃狀固體
英文
vitreous solid-
A crystalline solid is characterized by a unit cell containing an arrangement of atoms repeated indefinitely ; noncrystalline or glassy solids do not have a unit cell
晶狀固體的區別特徵是，它有一個單位晶格，這個單位晶格包含著無限重復著的原子排列。非晶體或象玻璃的固體沒有這樣的單位晶格（或晶胞）The influence of nano - al2o3 on the sintering and the properties of the si3n4 ceramics was researched in this paper. the samples with different amount of nano - al2o3 were obtained by using pressureless sintering at 1600, 1650, 1700 in the nitrogen atmosphere. the microstructure and the composition of the ceramics were determined by the means of x - ray, sem, micro - hardness meter etc. it is show that the sisty ceramics can be densified at 1650c to % percent of the theory density through the addition of nano - al2o3 ( the value could be 90 percent by other technique ). the crystalline growth of the cylindrical - si3n4 and the ratio of its longitude to its diameter are increased with the addition of nano - al2o3. a uniform microstructure and an fined crystal as well as more sialon phases can be obtained in the si3n4 ceramics through the addition of that
實驗結果表明：在碳管爐中、氮氣保護下進行燒結，添加劑為納米al _ 2o _ 3粉末時，由於納米粉末的高活性、高燒結驅動力，在1650就可使si _ 3n _ 4完全地燒結，並使其緻密度可達理論密度的96以上（比其它工藝高6左右） ；同時，納米al _ 2o _ 3地加入大大促進了長柱狀? si _ 3n _ 4的生長和發育及柱狀晶長徑比的提高，使微觀結構均勻、細化，形成了更多力學性能優異的固體? sialon相，減少了不利於陶瓷材料性能的晶間玻璃相，凈化了晶界。To make cds / k4nb6o17 powder on the base of the k4nb6o17 powder which by the courses of ion exchanging, amine intercalation, sulfuration etc. to obtain cds / k4nb6o17 thin film through the same course of making cds / k4nb6o17 powder on the base of k4nb3o17 thin film on the quartz which made by the spin coating and after heat treatment. to make experiments with additives ( na2so3, 0. 1mol / l ) of photocatalytically decomposing water into h2 and o2 to evaluate the photocatalytic activities of the catalyst knb6o17 powder, cds / k4nb6o17 powder, k4nb6o17 film, cds / k4nb6o17 film. the crystalline structures of the midst powder and film productions were investigated by using the x - ray diffraction ( xrd )
本課題的主要內容是：高溫固相反應合成具有層狀結構的k _ 4nb _ 6o _ （ 17 ）晶體材料，然後以此為母體材料，通過離子交換、層間胺插入、硫化處理等過程制備出cds / h _ 4nb _ 6o _ （ 17 ）粉末形式的光催化材料；通過旋轉塗覆法在石英玻璃基片上制備了k _ 4nb _ 6o _ （ 17 ）薄膜，採用一定的熱處理制度后對薄膜分別進行離子交換、層間胺插入、硫化處理等處理過程制備了cds / h _ 4nb _ 6o _ （ 17 ）薄膜形式的光催化材料。Containers for pharmaceutical dispensing - specification for glass and plastics containers for solid dosage forms, semi - solids and powders
