In this study, new benzo[l,2,3]thiadiazole derivatives were designed according to relationship of structure and efficacy. The 9 novel compounds were synsthesized with following reactions. The chlorine atom in 2-chloro-3,5-dinitro-benzoic acid as beginning raw material was substituted by 2-methylpropane-2-thiol, esterified then with bromoethane, reduced by iron powder and cyclized to obtain ethyl benzo[l,2,3]thiadiazole-7 after diazonation reation.

本论文根据苯并噻二唑诱导剂的构效关系设计了新的苯并噻二唑的结构，并合成了9个未见文献报道的化合物，合成步骤如下：采用2-氯-3，5-二硝基苯甲酸为起始原料，苯环上的氯原子被叔丁基硫醇置换，羧酸由溴乙烷酯化，硝基由铁粉还原，随后经重氮化关环生成苯并[1，2，3]噻二唑-7-羧酸乙酯。

Thromboplastic function was improved after PE. The configuration of peripheral blood RBC remained stable.

凝血功能状态明显改善，而外周血细胞计数和红细胞形态则不受血浆置换治疗的影响。

Plasma exchange therapy can recover the liver function and improve the thromboplastic mechanism, and decrease the abnormal immunological reaction of patients with severe viral hepatitis, and maintain stabilization of inner environment. The PE therapy is safe and effective for severe viral hepatitis.

血浆置换治疗可以改善重型肝炎患者的肝功能和凝血功能状态，减轻异常免疫反应，维持内环境稳定。

Hyundai isn't keeping quiet about its future product line, with the company's U.S. chief previously revealing details about the company's future hybrid and electric plans and now details about the company's replacement for the Tiburon.

现代不是保持缄默其未来产品线，与该公司的美国首席此前透露详细了解公司未来的混合动力和电力的计划，现在详细介绍该公司的置换蒂伯龙。

Taiwan was a time of uncertainty and cultural heteroglossia from 1970s to 1990s. The transition from traditionality to modernity was a process of conflict, rise and fall, replacement and hybridization of these two forces.

一九七○年代至九○年代之间，台湾经历了不确定的、众声纷呈的年代，从「传统性」到「现代性」的过渡，其实是两种属性的冲突、消长、置换，乃至交杂。

The optimum conditions of PSE extraction of isoflavonoids from Pueraria lobata were as follows: methanol as solvent, temperature at 140℃, pressure under 8.27 MPa, 10 min duration and transpositional volume as 60%.

优选出最佳提取条件：溶剂为甲醇；温度140℃；提取时间10 min；压力8.27 MPa，置换体积为60%，并与葛根药典提取方法进行比较，结果表明：加压溶剂提取法具有提取时间短、溶剂消耗少、提取效率高、重现性好、操作模式多样化以及操作过程自动化等优点，将有助于中药质量控制提取过程的标准化。

The variations consisted of point mutation (transition,transversion and deletion).

变异主要为点突变，包括碱基置换和缺失。
