稳定化

In an acetate buffer of pH 6.0,and in the presence of CTMAB,a stable complex,having the mole ratio of 1 to 3,was formed between cobalt ion and nitroso R salt,which was concentrated on C18 solid phase extraction column,achieving a concentration multiplication of 100 times.

研究了用亚硝基R盐离子对固相萃取光度法测定钴，在pH 6.0的HOAc-NH4OAc缓冲介质中，溴化十六烷基三甲基铵存在下，亚硝基R盐与钴反应生成3∶1稳定络合物，该络合物可用C18固相萃取小柱富集，富集倍数达100倍，小柱上富集的络合物用乙醇洗脱后用光度法测定，钴的质量浓度在0.05~5.0 mg.L-1内符合比耳定律。

Problems exist in the structure of staff and organization and managing system as follows: personnel examination and managing structure are strongly dependent; managing system of personnel examination is not scientific and keeps in disorder; the working staff of examination comes from different sources and are not well qualified; professional managing staff in charge of examinations, stable invigilators and high-leveled experts making and checking exams are not sufficient.ii.

在人员、组织结构及管理体制方面存在的问题有：人事考试及管理机构依附性强、独立性差；人事考试管理体制不顺，存在着多头管理、各自为政的混乱局面；考务工作人员来源杂、素质差，号业化、职业化程度较低，缺少专业的考务管理队伍、稳定的专业监考队伍和高水平的命题评卷专家队伍。

The influence of Pb-contamination on microstructure and shear strength of SnAg/Cu and SnSb/Cu solder joints prepared by SMT were studied by mixing eutectic SnPb solder paste into leadfree solder pastes.

与常用的Sn62Pb36Ag2焊点对比，Sn96.5Ag3.5和Sn95Sb5焊点在高温时效过程中组织结构更稳定，界面金属间化合物的生长速率和体焊料的粗化程度均低于SnPbAg焊点；同时，焊点的剪切强度较高。

Then, in analogy with the annealing of metals, the temperature is made high in the early stages of the process for faster minimisation or learning, then is reduced for greater stability.
