在高速搅拌池中，分别采用界面吸附法和显微照相法测定ＴＲＰＯ（三烷基氧膦）－煤油／１．０ｍｏｌ／ＬＮａＮＯ３溶液体系两相接触界面积。界面吸附法是采用有机相取样器取出本体有机相，通过测量搅拌前后有机相中ＴＲＰＯ浓度的变化，结合ＴＲＰＯ界面吸附参数计算出两相界面积。采用界面吸附法测定了微量ＴＲＰＯ浓度体系在搅拌池中的界面积，根据实验结果回归了两相界面积关联式，计算值与实验值的相对偏差小于５％。采用显微照相法测量了低浓和高浓ＴＲ－ＰＯ两组体系在不同搅拌条件下的界面积，其结果与界面吸附法关联式计算值基本符合。对两种测定方法的优缺点进行了比较、评价。

W/Cu Functionally Graded Materials (FGM) was designed not only for reducing the thermal stress caused by the mismatch of thermal expansion coefficients, but also for combining the features of W, Mo - high plasma-erosion resistance and the advantages of Cu - high heat conductivity and ductility. Four different fabrication processes for W/Cu or Mo/Cu, including hot-pressing, Cu infiltration of sintered porosity-graded W skeleton, spark plasma sintering and plasma spraying, were investigated and compared. It was foundthat the hot-pressing process is difficult to keep the designed composition gradient, while the other three processes are successful in making W/Cu or Mo/Cu FGM. Meanwhile, microstructures and composition gradients are analyzed with SEM and EDAX.

作者： WU Zhangwen, GOU Chengjun, YANG Dailun, PENG Xiufeng, HE Fuqing & LUO Zhengming Key Laboratory for Radiation Physics and technology of the Education Ministry of China institute of nuclear Science and technology, Sichuan University, Chengdu 610064, China Key Laboratory for Radiation Physics and technology of the Education Ministry of China China institute of nuclear Science and technology Sichuan University Chengdu China

The electron-induced L-shell X-ray par- tial production cross sections, total production cross sections and mean ionization cross sections for Ho and Os have been measured as functions of electron energies from near threshold up to 36 keV by using a thin target with thick substrate technique. The influ- ence of the electrons reflected from the substrate was corrected by using the electron transport biparti- tion model. Also, the corrected measured results were compared with theoretical predictions proposed by Gryzinski and McGuire.
