Graphite microcrystals are the product of coal graphitization and widely exist in graphitized Yongan Coalfield, Fujian Province, China, which is direct mineralogical evidence for transformation to graphite. Optical microscopy, scanning electron microscopy (SEM) micro-Raman spectroscopy were used detect morphology microstructure situ graphite microcrystals. The results show that volume proportio...

In order to improve the downhill regenerative braking control effect of hybrid electric vehicle (HEV), this paper designs a method for (HEV). Firstly, structures system, auxiliary system and eddy current retarder (ECR) are analyzed. Secondly, torque ECR when HEV is calculated. Then, process dynamically analyzed, force distribution constraint realized according relevant laws regulations. Finally...

introduction: this study seeks to discuss the light wave transport characteristics variation along the pericardium meridian under different pressures. methods: we selected 36 healthy students at the school for this study, tied up the desktop blood pressure cuff onto subjects’right proximal arms, fixed the detection probe immovably on the neiguan (pc6) acupoint and the reference point which was ...
