As a global leader in the field of Bismuth chemical, we had set up Representative Office and Sells Company in Shenzhen and Shanghai.

作为全球铋化工行业的龙头企业，本公司已在中国深圳和上海分别成立了办事处和销售公司。

The classification, characteristics, and application results of tin, tin lead and tin bismuth electroplating were summarized.

总结了电镀锡、锡铅合金和锡铋合金的分类、特点及应用情况。

This change has influence on both the rate of extraction and the recovery of silver, gold and bismuth from used concentrates.

这一变化对银、金和铋从被采用的精矿中萃取速率和回收速率都有影响。

RESULTS:In the Chenxiang Lubailu table,the identification of bismuthic salt positive result with dilute nitric acid instead of hydrochloric acid and the white precepitation formed in identification of magnesian was bismuth hydroxide sediments,it was easy and accurate to identify bismuthic salt by adding ascorbic acid.

结果：该片中的铋盐碘化钾鉴别反应，用稀硝酸代替盐酸做溶剂，呈正反应；镁盐氯化铵-磷酸氢二钠鉴别反应，加氨试液后，析出的白色沉淀不是Mg2，而是Bi3，该沉淀在氯化铵试液中不溶，干扰镁盐鉴别；铋盐含量测定项，用加抗坏血酸掩蔽剂的方法，排除Fe3+的干扰，使终点颜色稳定，易于准确判断。

On the basis of investigating the developments of inorganic mesoporous material's syntheses and applications, mesostructured tin oxide, bismuth oxychloride, lead sulfide, bismuth sulfide, titanium phosphate and zinc phosphate were synthesized by Sol-Gel and hydrothermal techniques, employing the neutral surfactant organic amine and anion surfactant alkyl sulfonate as templates.

The SBT thin films with STO seeded layer on MFIS structure also appear prefer (115),(006) orientation and good crystallinity. The seeded layer of STO effectively resists the diffusion of Bi into Ir bottom electrode on MIM structure. The remanent polarization and leakage current density of Sr0.8Bi2.6Ta2O9+x thin films with STO seeded layers are significantly improved. In MFIS structure, the Sr0.8Bi2.6Ta2O9+x thin films with STO seeded layer are improved memory window and lead to lower leakage current at low voltage.

在具有STO晶种层基材上沉积之钽酸锶铋铁电薄膜於700℃淬火后，无论在MIM和MFIS结构上皆可得完美(115)方向之SBT结晶相，而STO的种晶层在MIM结构中确实可以有效的阻止铋原子扩散进入底电极，而降低漏电流，在MFIS结构中虽然得到一较小极化值，但由於铁电层所分配到的电场值反而因介电常数值降低而增加，因而得到较大的记忆窗。

The dynamic variation in content of cndogenous abscisic acid,indoleacetic acid,gibberellinsand isopentenyladenodines of normal juvenilefruit and dropped fruit was measured with enzyme linked immunosorbent assayin the course of physiological fruit drop of 'Shuizhang Longan.

应用酶联免疫法测定了水涨龙眼生理落果期间正常幼果和脱落幼果中内源激素ABA、IAA、GAs及iPAs含量的变化。
