铸铁在700℃时氧化过程的观察

利用光学显微镜、电子探针以及扫描电镜研究了灰铁、球铁和蠕铁在７００℃时的氧化过程。结果表明：（１）灰铁的氧化主要沿石墨与基体的相界面进行，初生奥氏体枝晶对氧的侵入具有一定的阻碍作用；（２）球铁是沿晶界比先氧化来实现其间接氧化的；（３）蠕铁氧化的模式主要取决于蠕化率的高低。     

人胎盘泌乳素的提纯及裂解片断免疫学特性的研究

采用人胎盘泌乳素（hPL）-亲和层析和抗人血清抗体-亲和层析技术，从胎盘匀浆中提取hPL纯品，经圆盘电泳、免疫电泳及交叉试验证实为单一成分。溴化氰水解后的产物，以高效液相色谱分析。分离出7个肽链片断峰，分别用hPL和人生长激素（hGH）放免法检测其活性，其中第6肽链片断无hGH免疫活性，若用此片断制备特异抗体，可避免与hGH出现交叉反应。     

Effect of additives on formation of natural gas hydrate

The formation of natural gas hydrate (NGH) is studied in this work. Kinetics data of hydrate formation with no agitation were collected at various concentrations of the aqueous solutions with different additives such as alkylpolyglucside, sodium dodecyl benzene sulfonate and potassium oxalate monohydrate. Various kinds of additive increased the formation rates of NGH and its storage capacity and reduced the induction time of NGH formation. Moreover, the storage capacity, the induction time and the hydrate formation rate were influenced by the concentration of the aqueous solution.
