钢铁研究学报(英文版)

In blast furnace (BF) iron-making process, the hot metal silicon content was usually used to measure the quality of hot metal and to reflect the thermal state of BF. Principal component analysis (PCA) and partial least-square (PLS) regression methods were used to predict the hot metal silicon content. Under the conditions of BF relatively stable situation, PCA and PLS regression models of hot metal silicon content utilizing data from Baotou Steel No6 BF were established, which provided the accuracy of 884% and 892%. PLS model used less variables and time than principal component analysis model, and it was simple to calculate. It is shown that the model gives good results and is helpful for practical production.

利用反应磁控溅射法制备了半导体锡锑氧化物薄膜 (TAO). 根据霍尔效应测试结果，当Sn/Sb 原子比处于0.22~0.33范围内时，TAO薄膜是p型导电的，在此范围之外，TAO薄膜是n型导电的. 光学带隙测量结果表明,不同Sn/Sb比的TAO薄膜的禁带宽度基本相同(~3.9eV).构造了一个全透明的PN结，其中n区为Sn/Sb原子比为0.5的TAO薄膜， p区为Sn/Sb原子比为0.33的TAO薄膜.n区TAO的电极用铟锡氧化物（ITO），p区TAO的电极用Cu薄膜.实验结果表明，由于两种导电类型的TAO薄膜具有相同的禁带宽度，上述透明PN结构具有典型的准同质PN结的整流特性.

Improved Nonlinear Equation Method for Numerical Prediction of Jominy EndQuench Curves

钢铁研究学报(英文版)

Without considering the effects of alloying interaction on the Jominy endquench curves, the prediction results obtained by YU Baihai′s nonlinear equation method for multialloying steels were different from those experimental ones reported in literature. Some alloying elements have marked influence on Jominy endquench curves of steels. An improved mathematical model for simulating the Jominy endquench curves is proposed by introducing a parameter named alloying interactions equivalent (Le). With the improved model, the Jominy endquench curves of steels so obtained agree very well with the experimental ones.
