Deployable radiator is a radiation cooling device which is folded next to side wall of spacecraft while launching, and can expand itself after the spacecraft is on track. It can effectively improve the cooling capacity of the spacecraft. In this paper, the current research and development situations of the deployable radiator were studied and analyzed. Depending on this, design and simulation of the...
In this paper, conventional B-mode imaging and pulsed Doppler were employed to investigate spatial-temporal distribution of residual cavitation bubbles generated by pHIFU thrombolysis within a vessel. The HIFU pulse sequences had various acoustic parameters including pulse duration (PD = 10, 20, 30 µs), duty cycle (DC = 1∶10, 10∶20, 1∶30) and the number of pulses (n = 5, 10, 20). A non-transparent...
