ALGORITHMIC SYNTHESIS OF GENERAL NON-SHARP SIMPLE DISTILLATION COLUMN SEQUENCES

An algorithmic approach was used to select recoveries for non-sharp sequence designs. Simple distillation columns were employed. The non-key component distribution was modeled using the Fenske equation. The combination of producing impure products and allowing non-key component distribution, results in a large search space. With this large search space size and software limitations, five problems were solved (see summary table in the Design Examples sub-section). The optimal non-key component distribution was found to be significant but not necessarily maximal. Parallel processing was selected as optimal in contrast to the more traditional sequential processing.

室温磁制冷材料La（Fe0.94Co0.06）11.7Si1.3在去离子水中腐蚀行为的研究木

针对La（Fe0.94Co0.06）11.7Si1.3磁制冷材料在去离子水中的腐蚀行为进行了研究，结果表明，腐蚀速率随时间的变化而变化，开始时腐蚀速率较快，随着时间的延长，腐蚀速率逐渐变慢。XPS能谱分析表明，腐蚀产物主要由γ-Fe2O3、Co（OH）2及H2SiO3组成，产物形态较为疏松，不足以对基体形成有效保护。腐蚀产物中没有发现La的信息，其具体原因有待在后续工作中进一步深入探讨。     

纸上色层分离重量法测定铌铁合金中铌的改进

以国标《GB3654．1—83》方法为基础，试样采用氢氟酸、硝酸溶解后，适当调整展开剂配制比例，将其加大HF的浓度，降低HNO，的浓度，使用效果良好，缩短了密闭展开时间，提高了分析速度。     

Distribution of diethylstilboestrol in pigs

The synthetic growth promoter diethylstilboestrol (DES) administered orally to pigs can be detected by radioimmunoassay (RIA) analysis of kidney, liver, faeces, bile and urine from animals fed continuously to slaughter, but not in muscle, fat or plasma. If treated animals are fed on material not containing DES for 72 h prior to slaughter, then the levels of parent compound and metabolite in all products decrease to become not significantly greater than those in control animals. The gross metabolism of DES in pigs and bovines appears to be similar.
