查询词典 dissolution

To distinguish the fake whitened nephrite jades from the natural ones becomes a challenge to archeologists and antiquaries. This study mainly inquires into the reactions of nephrite during different conditions of acid/base/heat treatments, to find out the characteristics of fake whitened nephrite jade. The surface structure, whitening conditions of nephrite and elements dissolution in acid/base solutions are examined. Non-destructive Raman spectroscopy is also used to observe their crystal structure changes in each stages of treatments.

目前一般市面上玉器仿古白化的方法主要为酸处理、碱处理及热处理，因此本研究主要探讨在酸、碱处理及热处理作用之下，各阶段新鲜闪玉样品外表白化的情形、表面的显微结构变化，元素於酸、碱溶液的溶出情形，并以拉曼光谱非破坏性的分析来建立在酸、碱处理及热处理下的闪玉拉曼光谱资料。

Just like local pollutants or dissolution of the conglobated material, generally speaking it is a lower surface tension crater receptor of surface tension.

就像局部污染物质或溶解不完全的球形物质，一般来说其表面张力都要低于缩孔受体的表面张力。

The results showed that after the adding starch to the sheet, the viscosity of the PVA solution increased, the dissolution time of the sheet got longer, the rate of enlargement in water was smaller, the rate of moisture became smaller, stretch intensity enhanced and the change of shape diminished; also it could be seen from the surface of sheet that the starch existed in PVA sheet as the shape of conglomerating particle.

结果表明，加入淀粉后，PVA溶液的粘度增大，膜的溶解时间变长，水上伸长率变小，含水率变小，扯断强度增强，形变缩小；通过膜表面观察，发现淀粉在膜中以聚集颗粒状态存在。

Secondly, spinnability of SF dope was studied. The results indicated that the higher concentration of the dope and the less content of H2O would result in the better spinnability. And higher concentration of the dope had good spinnability whether the dissolution system containing minim EDTA or not. Pure EtOH and LiBr/EtOH (40/60, w/w) were used as solvent, to which minim EDTA was added. Then certain degummed SF was dissolved in the above mixed solvents to prepare the dope (21.7wt%) containing minim EDTA or not, respectively.

二、丝素溶液纺丝成型特性，结果表明纺丝液浓度较高及纺丝液中水分含量较少时再生丝素溶液有较好的可纺性，且无论体系中是否含有微量EDTA，较高浓度纺丝液均具有较好的可纺性，因此采用无水EtOH 及LiBr/EtOH (40/60，w/w)作为纺丝溶剂，制得了纺丝液浓度为21.7wt%含微量EDTA 及不含EDTA 的可纺性良好的丝素溶液。

The L2 glass with 30 mass% Al2O3 filler (L30A) can be fully densified at 800oC in 1 h and devitrified at 850oC for 10 min. The sintering scheme has been optimized to achieve limit dissolution of Al2O3 grain and crystallization of equi-axial LaBO3 and flaky LaAl2B3O9 crystals. The final matrix has limited glassy phase.

L2玻璃添加30 mass%的氧化铝（简称L30A）於800oC持温一小时并於850oC作十分钟的结晶处理可达完全致密，整体的烧结流程设计亦已最佳化，微结构观察中可发现等轴LaBO3及片状LaAl2B3O9之结晶体，其烧结后之基地仅残存有限的玻璃相。
