The round trip flow time is cut short from two hours to ten minutes and the method adopts silver nitrate-bismuth nitrate united screening method to eliminate the disturb of chorine ion instead of strenuous noxious mercury sulfuric.

本方法适当提高硫酸浓度，强化了重铬酸钾的氧化效率，使回流时间由 2h缩短到 10min ；并且用硝酸银和硝酸铋联合掩蔽法能消除氯离子的干扰，代替剧毒的硫酸汞。

Adopting TPB as catalyzer of solidifying chemical reaction,it can distinctly quicken reactive rate. It is relatively reasonable for controling reactivetemperature at 50℃. Vacuumized and deposited one day at normal temperature before hightemperature solidifying chemical reaction, which is propitious to remove air bubble frompropellant columniation.

采用三苯基铋作固化催化剂，可明显加快固化反应的速度，固化反应的温度控制在50℃比较合理，在高温固化前抽真空和常温下放置一天有利于排除药柱中的气泡。

The effect of cold-deformation amount and annealing temperature on the dezincification of the unleaded free-cutting brass were investigated.

采用脱锌腐蚀深度测量方法，光学显微镜分析和SEM等分析方法，研究了不同的冷变形量和退火温度对无铅易切削铋黄铜的耐脱锌腐蚀性能的影响。

A white, crystalline, brittle, highly diamagnetic metallic element used in alloys to form sharp castings for objects sensitive to high temperatures and in various low-melting alloys for fire-safety devices.

铋：白色、晶状、易碎、高度抗磁的金属元素，用于高温敏感物体的合金中，以铸成锋利物件，多种用于防火安全设施的低熔点合金。

Through systematic field survey, sample collection, indoor ICP-MS analysis and SEM energy spectrum analysis, the authors have reached the conclusion that along the Bangong Co-Nujiang metallogenic belt bismuth content of single samples in 12 ore deposits or ore spots can meet the requirement of the cut-off grade, and that in 9 ore deposits or ore spots can meet the requirement of the industrial grade.

本文通过系统的野外调查与样品采集、室内ICP-MS与扫描电镜及电镜能谱方法分析，确定班公湖-怒江成矿带12个矿床单件样品铋含量达到边界品位的要求， 9个矿床单件样品达到工业品位的要求，最高达到9575×10？

Diffuse-reflectance UV-visible spectroscopy and Raman spectroscopy analysis show that bismuth atoms in Bi-SBA-15 exist in a highly dispersed state, and locate mainly at tetrahedrally coordinated sites.

此外，为了考察进入分子筛中的铋原子的分布，对所合成的样品进行了XPS表征。
