1.2) Study of stress reaction to injured soybean cotyledon:The changes of UBC were observed with high sensitive single photon counter device in the stress reaction experiments of the soybean cotyledon (etilolation and green) after being injured.
4.This paper takes construction in loess tunnel of an expressway as example,analyzes deformation damage system to mountain and tunnel when excavating shallow buried side stress loess tunnel via finite element calculation,and it suggests the counter measure of back pressure back fill.
