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。

The results showed that the aluminum plates had a much better effect than zinc plates in identifying crystalline free silica. The all open-faced samples had good uniformity in the filter no matter how many middles were used, but not so good for the closed-faced sampling. The calibration curve had a good correlation coefficient (r=0.995). Due to different industrial operating patterns, the distribution of crystalline free silica concentration varied by the industrial environment. The dust consisted of 10- 30% of crystalline free silica in all samples obtained from the foundry environments. The crystalline free silica was accounted for less than 10% in the respirable dusts.

结果显示，因为铝板对於结晶型游离二氧化矽具有较良好的补正系数，因此做为本研究的基底标准吸收校正的校正元素；SKC铝制旋风分离器搭配开匣式滤纸匣於一阶中环、二阶中环、三阶中环均有良好之均匀度，反之，搭配闭匣式滤纸匣其均匀度均不佳；分析检量线具有良好线性关系(r=0.995)，因作业型态不同，作业环境会有不同的浓度分布，综观作业环境中可呼吸性结晶型游离二氧化矽之含量均小於10%以下，总粉尘结晶型游离二氧化矽之含量约为10 – 30%之中。

Rifampicin is bright red or dark red crystalline powder, scentless and odourless combined with other anti tuberculosis drugs, in the mean time rifampicin is also a refill of drugs which is drug-resistant to isoniazid or streptomycin.

本品为鲜红色或暗红色结晶性粉末，无臭，无味。利福平为高效广谱抗生素，主要与其他抗结核药合用，用于各种核病重病患者，也可作为对异烟肼和链霉素耐药菌株的替换物。

A large quantity of valuable data and results were obtained, which is of great importance to develop the theory for the designing and controlling of the properties of the crystallizable aromatic polymers.

研究过程取得了大量有价值的数据和结论，可为设计，调节及控制结晶性芳香族高聚物材料的性能提供必要的理论基础，并使得聚合物伸直链晶体应用于功能器件成为了潜在的可能。

The results of CRYSTAF test showed,along with the increment of the ethylene content,an increase in the tacticity of propylene homopolymers and decreases in the isotacticity、long crystallizable sequence content.

结晶分级分析测试结果显示，随着乙烯含量的增加，聚丙烯均聚物部分链结构规整性提高，结构规整、可结晶的长序列含量在减少，可见乙烯含量的变化规律直接决定上述参数的变化规律。

In the thin films of semicrystalline block copolymers there exist three driving forces: the interaction between substrate and block copolymer, crystallization of crystallizable component and microphase segregation between unlike blocks. The relative strength of these three driving forces can be regulated by various methods.

在这两类结晶性嵌段共聚物薄膜中存在三种作用力：基体和嵌段共聚物之间相互作用力、可结晶链段的结晶以及不同链段之间的排斥作用力。
