Nitrogen fixation of faba bean interacting with a non-legume in two contrasting intercropping systems，范分良，余常兵，A field experiment was carried out to quantify biological nitrogen fixation (BNF) using the 15N isotope natural abundance method in maize (Z
Amelioration of nitrogen difference method in legume intercropping，余常兵，李隆，Nitrogen difference method is commonly used to appraise biological nitrogen fixation, which is a well established aspect of plant condition. In an intercropping system, belowgr
In the process of eye tracking , a subject may focus on a point for a longer time, we call it fixation points, theprocess between fixation points is a saccade. Here, we investigate into the correlation between eye-tracking data andEEG(Electroencep
Accurate placement of pedicle screw (PS) is crucial in spinal surgery. Developing new real-time intra-operative monitoring and navigation methods is an important direction of clinical application research. In this paper, we studied the spectrum along
