结晶不明显的

But the crystal shows no change, only the crystallinity of aluminum hydroxide changes weakly.

细化现象明显：但添加剂对铝酸钠溶液种分产品的晶型不产生影响，仅产品的结晶度发生微弱变化。

Of all materials available, calcium phosphate cement is an important biomaterial for hard tissue repair because of its chemical and crystallographic similarity to the carbonated apatite in bones and has received considerable attention. CPC consists of a mixture of fine particles of calcium phosphate salts, the CPC powder can be mixed with water to form a thick paste that can conform to osseous defects to form degradable hydroxyapatite, therefore, CPC's moldability, together with its excellent biocompatibility and osteoconductivity, make it a highly desirable material for orthopaedic repair.

磷酸钙骨水泥是一种非陶瓷型羟基磷灰石类材料，生物学特性与骨的化学组成相似，其良好的生物相容性和骨传导性引起人们的广泛重视，同时具有可吸收性，良好的蛋白亲和性，可复合骨形成蛋白而具有骨诱导性，制备简便、固化迅速、易塑形、在结晶过程中不产热等许多明显的优势使其广泛用于骨缺损修复、骨强化和骨替代。

No entire nitrendipine crystals were observed visually in SEM photos. The results of X-ray diffraction and differential scanning calorimetry analysis indicated that the crystalline form of nitrendipine was highly dispersed in microspheres, so as amorphous state. The drug release rate of microspheres could be controlled with adjusting the ratio of solid dispersion carriers and retarding agents formulated. The agitation speed and temperature of the preparation process have distinct effect on micromeritic properties of microspheres. The release profiles of the microspheres were mainly affected by the stirring rate of paddle, the concentration of SDS and pH of dissolution medium. Cooling speed and time, however, have no evident influence on the drug release rate of the microspheres. The dissolution data showed that the mechanism of drug release from microsphers was mainly diffusion-controlled. The incorporation efficiencies of 3 batches sample were exceed 96. 8％, which implied that the current method was suitable for design sustained-release dosage form for poorly water-soluble drug.

在扫描电子显微镜下观察，在微球内外未发现尼群地平的完整结晶，X-射线粉末衍射和差示扫描量热试验结果也显示，尼群地平已经被高度分散在微球中；微球的释药速度可通过调整处方中固体分散体载体和阻滞剂的比例控制；制备温度和搅拌速度对微球的质量影响较大；溶出仪的搅拌速度，释放介质的浓度和pH对微球的释放有较大的影响；制备过程中的冷却速度和冷却时间对微球的释放行为影响不很明显；方程拟合的结果表明缓释微球的释药行为符合扩散机制；测定三批微球样品的包封率均在96.8％以上，表明该法适合于制备难溶性药物的缓释微球。

However, analysis results of SEM, WAXD, and mercury porosimeter demonstrated that the granule\'s topological morphology, crystal form and porosity were almost intact after the annealing treatment.

退火处理只是引起原生态聚丙烯粒子部分熔融和再结晶，使得结晶缺陷或者不完善部分趋于完善，其中150℃退火处理的效果最为明显。

The number and intensity of peaks of the thermoluminescent cutves are obviously related to stages of gold mineralization:the curve of the early barren quartz shows nearly Symmetric pattern; that of the major stage auriferous quartz is of multimodal type; the curve of the late quartz, low in gold, is marked by unimodal--bimodal type with rather intense luminescence.

石英热发光曲线的发光峰的数量和强度与金成矿阶段有着明显的关系：早期成矿阶段结晶的基本不含金石英，热发光曲线常为近对称的单峰型，发光强度较大；主成矿阶段形成的含金石英，热发光曲线为多峰型，常具最大的发光强度；晚期成矿阶段生成的含金性较差的右英，热发光曲线呈单峰-双峰型，发光强度亦较大。
