A positioning system platform based on the microcontroller MiniSTM32 was built to test the performance of the transceiver circuit. The experimental results showed that the positioning error of less than 3 cm was achieved in a space of 80 cm × 80 cm × 80 cm. </div>展开更多

Suku is thus a historically specific practice and a culturally specific form of women＇s narrative practice. By listening to and observing the post-Mao suku narrative performance of my grandmother, a retired State-Owned Enterprise （SOE） worker, I show that her suku is a gendered performance, a form of labor that blurs production and reproduction, and a form of embedded personhood; and that suku as a form of narrative persisted through the period of economic reforms, even though its intent and audience became transformed. My kin relationship with this particular suku performance allows an analysis of the impact ofsuku on cross-generational relationships--those between first-generation SOE workers and laid-off SOE workers in former SOE families. Furthermore, I argue that suku can be seen as a form of labor and self-valorization of Chinese women workers discarded in the new economy, and contrary to its original disciplinary purposes, as a form of resistance.展开更多
