摘要： A dual-stack air-cooled fuel cell includes two stack groups, a fan assembly, an air supply channel, a spoiler and a temperature control device. The fan assembly is centrally located in the air-cooled fuel cell, and is configured to generate an air flow field in the air-cooled fuel cell. The two stack groups are located at an air inlet side and an air outlet side of the fan assembly, respectively. The spoiler is arranged between the fan assembly and the two stack groups. The above components are connected through the air supply channel. The temperature control device is configured to detect surface temperature of the stack groups to adjust the rotation direction of the fan assembly, so as to alternately perform suction and blowing operation for the two stack groups to reach the heat equilibrium of the fuel cell.

摘要： A feedback apparatus and an FFT/IFFT processor. The apparatus comprises a radix-4 cascading operation module; radix-4 cascading operation module comprises: a twiddle factor generating unit, a complex multiplier, a delay switching unit, a butterfly operation unit, and an output switching unit; delay switching unit connects to the butterfly operation unit, complex multiplier, and output switching unit, respectively; and output switching unit connects to butterfly operation unit and delay switching unit. In present invention, on basis of the complex multiplier being fully utilized, and by using a dual-delay feedback structure circuit and designing a data delay buffer channel, the use efficiency of complex adders/subtractors is more effectively improved, the number of complex adders/subtractors required is evidently reduced, and circuit efficiency is significantly improved, thus effectively solving the problem in which radix-4SDF and radix-4SDC structures occupy a relatively large number of complex adders/subtractors.

摘要： The present invention relates to a bioelectrode for increasing abundance of cable bacteria, including an anode, a cathode, and a partition. The anode is horizontally disposed, and the cathode is disposed perpendicular to the anode. The anode and the cathode are separated by using the partition. An objective of the present invention is to provide a method for keeping a high abundance of the cable bacteria in sediments when oxygen content of overlying water is low and even in an anaerobic environment. The method can be further performed in a self-starting manner, and has a potential application prospect in ecological remediation of sediments.

摘要： A robust data transmission method in Internet of Things. Allocation information of a first time-frequency resource set and a description of a first transmission mode are sent by a base station to a first terminal, and a second time-frequency resource set is allocated by the base station to a second terminal. The first time-frequency resource set includes an overlapping resource set and a non-empty third time-frequency resource set. A second transmission mode of the first data packet is determined by the base station according to a continuity in time of resources in the third time-frequency resource set. A description of the overlapping resource set is sent by the base station to the first terminal. The second transmission method of the first data packet is confirmed by the first terminal, and the first data packet is received by the first terminal according to the first transmission mode and/or the second transmission mode.
