Developing from IC and PCB, the SIP (system in a package) has already been one of the most important development directions of future electronic system; therefore, we desiderate the study of testing design and test method. Being incapable of adding circuits for testable design, the SIP can only design test method and process according to the existing resources. Test method in this paper takes into...

Macroscopical analysis model of SMW composite retaining structure was made based on composite material mesoscopic structural mechanics theory, compound enhanced rule of transverse elastic modulus and transverse poisson ratio were studied theoretically. Theory results were corrected considered of Not coordinate deformation of structural steel and cement soil. modified formula of SMW composite structure...
