Described herein are syntactic foams comprising: (i) hollow filler particles; and (ii) an epoxy matrix; wherein, the epoxy matrix is characterized by an ordered microstructure comprising a plurality of vacancies that resides at interstices between the filler particles. The ordered microstructure of the syntactic foams provides the materials with lower densities and higher strengths compared with syntactic foams of the art. Methods of preparing the syntactic foams are additionally described.

The invention relates to a beacon system based on a hollow-core optical fiber, and the system employs the hollow-core optical fiber to transmit laser to a far-end optical processing unit, and the far-end optical processing unit carries out the optical processing of the laser, so as to generate visible light. The technical scheme provided by the invention has the beneficial effects that 1, the weight per unit length of the hollow-core optical fiber is far lower than that of a copper-core cable, and the extremely light dead weight enables the length of the used optical fiber to be far greater than that of the cable when the same weight load is reached, so that the effective laying radius of the beacon system is greatly expanded, and the service life of the beacon system is prolonged; the core bottleneck that the working distance is limited by the dead weight of the cable is solved. 2, the hollow-core optical fiber transmits laser energy, and Joule heat loss caused by the resistance effect of the cable is avoided in the transmission process of the hollow-core optical fiber; and secondly, the far-end optical processing unit is used for performing optical processing on the laser to generate visible light, so that energy loss in the electro-optical conversion process is avoided. By means of the end-to-end light-to-light conversion path, the energy utilization rate is greatly improved.

The application discloses a bidirectional resonant DAB control method of full working condition ZVS. According to a power interval of a given power, the working mode of the bidirectional resonant DAB is divided into an extremely light load mode, a medium-low load mode and a medium-high load mode, and then the three degrees of freedom of three-phase shift and frequency modulation are controlled. The application can switch among the three modes according to different given power conditions, can realize ZVS in a full working condition range (including a forward full working condition and a reverse full working condition), and can improve the circuit operation efficiency under heavy load and medium load working conditions.
