利用系统科学反馈基模分析理论，提出了系统成长上限模型上限逐步生成与消除法，通过构建江西电子信息产业市场需求成长上限子基模、人力资源不足成长上限子基模、政府支持有限成长上限子基模、资金不足成长上限子基模、创新能力不足成长上限子基模等5个基模，并对其做并运算，得到了江西电子信息产业系统成长上限基模，刻画了资金、市场、技术创新、人才与政府支持相互制约的关联关系。

By using Roche kit as standard, the amplification efficiency of different reagents were compared by Roche Light Cycler instrument for establishing real-time PCR reaction system. The primers were designed based on signature sequence of chromosomal DNA fragment and caf 1 gene in plasmid pMT1 of Y.pestis. And sensitivity and specificity assay were done with serial diluted Y. pestis EV76 strain and other bacterias. Then 275 Y.

采用SYBRGreenI随机掺入法，以Roche试剂盒为标准，比较两公司的DNA聚合酶，用鼠疫菌310 0 4建立荧光PCR反应体系；针对鼠疫耶尔森氏菌特异的染色体标识序列和质粒上F1抗原基因设计引物，检测其灵敏度和特异性，以盲测试验进行验证；在此基础上鉴定2 75株鼠疫耶尔森氏菌，并测试该法检测脏器污染模拟标本的灵敏度。

The present dissertation reviews the total synthesis of biotin, particularly on Hoffmann-La Roche\'s Lactone-Thiolactone approach. The Lactone-Thiolactone approach is presently the most competitive commercial route, which gives an excellent illustration of the gradual construction of the functionalized skeleton with the simultaneous solution of the stereochemical issues in a minimal number of steps.In 1970, Gerecke etc. of Roche Corp.

论文对生物素全合成的文献进行了综述，重点讨论了目前工业上最有竞争力的内酯—硫代内酯路线，展示了生物素是如何以最少的步骤去逐步构建目标产物的官能团骨架并同时解决立体化学问题的。1970年，Roche公司的Gerecke等报道了一条通过手性内酯，以较高收率并保持构型得到手性硫代内酯，从而直接合成d-生物素的方法后，该中间体内酯(3aS，6aR)-1，3-二苄基。

detectability：检测限

检出限(detection limit,limit of detection)、测定限(determination limit,limit of determination)与检测限(detectability)是分析化学中常见的名词术语,近年来,国内外一些文献多有论述[1~6].但目前国内出版物中对三者的定义、使用仍存在一些混乱现象,
