Abstract: The present invention provides a method for generating a droplet array on a microfluidic chip, comprising the following steps: assembling an upper chip and a lower chip to an initial position, a fluid channel of the upper chip partially or completely covering a microporous array of the lower chip; injecting a solution into a chip, the solution being partially or fully filled in the microporous array of the lower chip; and relatively moving the upper chip and the lower chip to a liquid dividing position, the fluid channel of the upper chip and the microporous array of the lower chip being overlapped no longer, and the solution being dispersed into the microporous array to form a droplet array. A contact surface between the upper chip and the lower chip is hydrophobic, and the microporous array sufficiently separates the generated droplets physically, thereby avoiding cross-contamination. The present invention can effectively control the size and shape of the generated droplet.

Abstract: A segmental precast composite-material composite-slab composite beam and a construction method thereof are provided, relating to the technical field of bridge design and construction. The segmental precast composite-material composite-slab composite beam mainly includes a segmental precast orthotropic composite top slab, a web, a bottom slab, and a wet joint between segments. The orthotropic composite top slab is composed of an orthotropic slab and an ultra-high-performance concrete layer (UHPC), and the interface connection of the orthotropic slab and the UHPC structural layer is achieved by a shear key. The UHPC structural layer is superposed with the orthotropic slab in segments in a precast plant to form a composite-slab composite beam segment to be entirely transported, hoisted and assembled, and the connection of the UHPC structural layers between the segments is achieved by casting a transverse wet joint in place.
