A theoretical modeling and computational simulation of the circular Si-diaphragm have been performed through the extensive study of stress and frequency response with the help of finite element method (FEM) within the framework of COMSOL. For a thin diaphragm (50μm), the Eigen frequency and the...
三星堆考古进入新的时期。 The Sanxingdui relic site, located 40 kilometers north of Chengdu on the banks of the Yazi River and west of Guanghan City,holds a civilization that dates back 4,800 years. It has yielded tens of thousands of exquisite cultural relics through archaeological excavations....
Pit houses are usually sunken and use the insulation properties of the original bottom layer to maintain indoor temperature. The insulated green roof and 7-foot deep underground hole of the Edgeland residence keep it cool in summer and warm in winter. The mechanical system combines circular heatin...

we subtract MSGNUMWRAPAROUND from all the MsgNum variables simultaneously. MSGNUMWRAPAROUND can be large so that we don’t need to do this often. It must be a multiple of MAXNUMMESSAGES so that the existing circular-buffer entries don’t need to be moved when we do it. 如果MsgNum值溢...
