Deep-seated rock fracture of valley slopes in China:A review
《Journal of Mountain Science》2023年第7期1984-2002,共19页PENG Yi ZHAO Qi-hua HAN Gang CHEN Yu-shu 
supported by the National Natural Science Foundation of China(Grant Nos.41272333);the National Key Research and Development Program of China(Grant Nos.2011CB013501)。
Deep-seated rock fractures(referred to as DSRF hereafter)in valley slopes are uncommon geological phenomena that challenge our previous understanding of slope unloading processes.These fractures weaken the strength an...

Non-undercutting condition and parameter optimization for cycloid ball planetary transmission
《Journal of Chongqing University》2017年第2期51-58,共8页张鹏 wang meng bao bing-bing 
Funded by the National Natural Science Foundation of China(Grant No.51405003)
The transmission performance of cycloid ball planetary transmission(CBPT) is affected by cycloid tooth undercutting directly, and the design of CBPT can be optimized by the non-undercutting condition. Firstly, the the...
