铁矿石中铁含量无汞法测定实验的改进

采用H3PO4-H2SO4-HNO3分解试样，改变Na2WO4的浓度和加液顺序，明确了TiCl3还原试样时的温度．此法与经典的无汞法相比，无显著性差异，且随机误差小、成功率高，可在实验教学中推广采用．     

基于交际法的课堂英语词汇教学

传统的语法翻译法词汇教学是以教师为主体进行讲授,学生听讲,参与度很低,教学效果不甚理想.而交际法词汇教学强调的是以学生为主体,将词汇应用于语境,通过提高学生对词汇的使用频率,实现学生对所学英语词汇的掌握.实践表明,通过课堂交际活动与教材及其它多种媒介的结合,可以在提高学生口头交际能力的同时,培养学生的书面表达能力.

HIs classification in HCR model for operator reliability study of nuclear power plants

The human cognition reliability model is used to study time-related human response interaction (HI). The classification of HI types is an important base. At present, the two types of HIS classification (i.e. SRK classification and CP classification) are based on subjective or objective characteristics respectively by which some phenomena can be hardly explained. Since the types were limited, they could not meet the requirements. The integrate approach of HIs classification is compatible with the original methods, and HIs are classified according to subjective and objective characteristics. The integrate approach contains more detailed types and has higher precision. It is more advantageous and convenient for the classification of HIs. The integrate approach has been used in the study of operator reliability for nuclear power plants in China. The results were satisfactory, and by which the integrate approach was verified.

The tectonic uplift of the Hua Shan in the Cenozoic

Six granite samples were collected from six difference elevation locations at the Hua Shan in a main ridge of the Qinling Mountain. Apatite and zircon separated from these six samples were dated by the fission track technique. An assessment of the Cenozoic uplift or exhumation rate was obtained from the altitude difference of sampling samples dated by fission track, and from the difference of fission track dates of both apatite and zircon for a sample. The preliminary results suggest that the beginning of uplift of the Hua Shan was as early as 68.2 MaBP and the uplift rates for different periods are 0.02–0.19 mm/a (from the elevation difference) or 0.12–0.16 mm/a (from two mineral fission track dates). The average uplift rate is 0.12 mm/a (from the elevation difference) or 0.14 mm/a (from two mineral fission track dates). The uplift of the Hua Shan might accelerate since (17.8±2.0) MaBP, and the average uplift rate is about 0.19 mm/a.
