Moreover, over the years, I have enjoyed looking through the issues of the existing Chinese Journal of Rock Mechanics and Engineering （CJRME）. The content of this Journal, initiated in 1982, is partially accessible to foreigners because the Contents, paper Abstracts and Figure captions are published in English. The number of rock mechanics articles in each monthly issue of the Journal is far more than any other country can produce. This activity is also reflected in the fact that China now has more ISRM members （502） than any other country -- and the number is no doubt continuing to grow! Furthermore, the Editor-in-Chief of the CJRME, Professor Feng Xiating, will be the next ISRM President for the period 2011-2015.展开更多

Scharnowski, C.J KalerThe separating/reattaching flow over an axisymmetric backward-facing step is analyzed experimentally by means of particle image velocimetry. The main pur- pose of the measurements is the investigation of the mean flow field as well as of the Reynolds stress distributions at Ma.7 and at Re33 × 10 5ed on the step height. Due to the strong progress of optical flow measurements in the last years it was possible to resolve all flow scales down to 180 μm （≈ 1% step height） with high precision. It was found for the first time that the Reynolds stress distribution features a local minimum between the first part of the shear layer and a region inside the recirculation region.展开更多
