结晶化

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。

It usually aims at material reinforcement, enhanced crystallization rates and plasticizing for easier processing.

它通常旨在材料加固，提高结晶率和塑化更容易处理。

Firstly, polyunsaturated fatty acid was enriched from saponified single cell oil by means of low temperature solvent crystallization, which gave a PUFA-rich fatty acid fraction with 74.71 wt% arachidonic acid and a corresponding yield of 97.1%.

首先，用低温溶剂结晶从皂化单细胞油中浓缩多饱和脂肪酸，结果可得到一富含PUFA之脂肪酸，其中花生四烯酸之含为74.71 wt%，产则为97.1%。

Although CdS and NiSe belonged to the same crystal system, they had a great difference in the morphology of products produced in ethylenediamine by a solvothermal process. By making a crytallographic comparison between CdS and NiSe, I thought that fourcoordinated crystals were more prone to grow one-dimensionally in the stacking direction of tetrahedrons. This hypothesis could also be embodied in many examples.

硫化镉和硒化镍的晶体结构都为六方晶系，但在以乙二胺为溶剂的溶剂热条件下合成出的产物形貌有很大的差别，我们通过对两类晶体结构的结晶学比较，我们认为4配位的晶体更趋向于生成一维纳米材料，并提出生长方向即为四面体堆积方向，这一假设也能得到许多例子的证实。

The contamination of the different target, the oxidation and the carbonization during the sputtering process and the crystal structure of Pd all have the significant influence in the performance of the rare earth films.

研究结果表明，衬底温度为150℃，Ar~+的溅射气压为4.5×10~(-1)Pa时比较适宜；溅射过程中，不同溅射靶之间的相互污染、氧化、碳化以及Pd保护层结晶性能的好坏等都对稀土薄膜的性能有很大影响。

Cellulose acetate butyrate,which is widely applied as coatings additive, is synthesized in the heterogeneous system. The activation is required because of the strong hydrogen intramolecular and intermolecular bondings and the regulation of the crystalline region in cellulose microfibrils.

中文摘要纤维素醋酸丁酸酯（Cellulose acetate butyrate是一种广泛应用于涂料工业的添加剂，由于纤维素具有分子内与分子间强氢键作用以及纤维素纤维的局部规整的结晶序列等特征，一般纤维素在酯化反应前都需要进行预活化处理，工业上纤维素醋酸丁酸酯的合成方法一般都在非均相体系中进行的。

The test results show that the crispest HAZ occurs in the process of welding of the 14MnNbq steel on the first heat circulation submerged welding overheat zone and the second heat circulation submerged welding overheat zone plus the not entirely re crystallized zone. The 14MnNbq steel has a tendency of being crisper due to overheat than the SM490C steel is. In order to ensure the toughness of the welding HAZ′s, the welding wire capacity should be properly controlled during welding.

由试验结果表明，14MnNbq钢焊接HAZ最脆区出现在一次热循环的埋弧焊过热区及二次热循环的埋弧焊过热区+不完全重结晶区；14MnNbq钢比SM490C钢有更强的过热脆化倾向，为确保焊接热影响区韧性，焊接时应适当控制焊接线能量。

Controlling the unidirectional solidification process and using passivation and impurity gettering treatments are the main approaches to improve the solar cell properties.
