Abstract: An engineered recirculating aquaculture fish pond and a fish culture method are provided. The engineered recirculating aquaculture fish pond is simple to operate, has strong adaptability to different culture environments or culture varieties, and is not only suitable for large-scale aquaculture enterprises but also suitable for small-scale farmers. An aeration water lifting device is designed to simultaneously perform aeration and drainage, which can reduce the use of electric equipment, decrease the production and maintenance cost, improve the cost performance of single equipment, and save the internal use space of the pond. Nozzles are arranged in more than two directions, which is convenient for performing aeration in different directions, uniformly dispersing impurities carried in water in a deep ditch, intercepting to reduce local blockage, improving a single utilization rate of an intercept structure, and preventing heavier impurities from accumulating at a channel bottom of the deep ditch.

Abstract: A method of preparing a thermally conductive composite including: a) mixing 15% to 60% by weight of a polymer matrix with 0% to 85% by weight of a high-aspect-ratio thermally conductive filler having an aspect ratio of at least 5:1; and (b) mixing a polymer melt obtained from step (a) with 0% to 85% by weight of a low-aspect-ratio thermally conductive filler having an aspect ratio of 2:1 or less. By changing the weight ratio, the structure and mechanical properties of the low-aspect-ratio thermally conductive filler and the high-aspect-ratio thermally conductive filler, thermal conductivity anisotropy can be tuned. A thermally conductive composite having thermal conductivity anisotropy in the range from 1 to 4 is also disclosed.
