摘要： Disclosed is a high-temperature high-linear-pressure micro-eutectic method for enhancing the strength of a PTFE-based film, relating to the technical field of polymer composite materials. The method comprises: pushing a PTFE-based nano-functional composite film forward at a speed of 6-8 m/min in a high-temperature high-linear-pressure micro-eutectic cavity with a length of 1.5 m at 380°C, controlling the linear pressure of the surface of the PTFE film to be 50-80 N/m, and under the coiling traction of a film coiling roller outside the cavity, enabling the molecular chains of the film to shrink and generate a eutectic, wherein multiple micro-eutectic molecular structures are arranged in parallel with each other. The film has a density of 2.1 kg/m3, and has nanoscale macromolecular aggregates and an ultra-micro-structure morphology with nanoscale and micronscale size concave and convex geometries of an average surface size of 10-20 um, a height of 5-10 um, and a spacing of 10-20 um. The bonding and peeling strength is improved, and the method can be used for preventing the icing up of various types of fan blades.

摘要： A method for calculating a head loss coefficient and branch pipe flow distribution of a multi-point intake port, comprising: inputting and determining structure and size information of a multi-point intake port; determining a head loss coefficient; determining a head loss coefficient form of a junction; pre-estimating or adjusting a tested and calculated flow; testing and calculating head loss coefficients at branch pipes; comparing head losses calculated for two flow paths; and performing overall calculation. Head losses and flow distribution proportions can be finally accurately calculated by adjustment of flows of branch pipes and repeated calculations of head loss coefficients by using iterative calculations of head loss coefficients of flows in two directions, so that relatively accurate head losses and flow distribution proportions can be obtained without specifically constructing a model for simulation, thus greatly reducing design costs and time.

摘要： A method for performing ecological dispatching on a trunk stream reservoir by taking inflow water from an interregional tributary into consideration. By means of investigation and research, ecological and hydrological requirements for the spawning of target fish at a spawning ground downstream of a trunk stream are specified; high-flow pulse encounter analysis, related to fish spawning, of a trunk stream and a tributary is launched; high-flow pulse feature indexes of the trunk stream and the tributary during a fish spawning period over the years are sorted and are subjected to statistical compilation; a key index of a starting condition for a trunk stream reservoir coordinating with a tributary to perform ecological dispatching is identified; important parameters for river course calculation are determined according to diachronic hydrological data; and a reservoir ecological dispatching model is constructed so as to implement a method for performing ecological dispatching on a reservoir by taking inflow water from an interregional tributary into consideration. In the method, taking inflow water from an interregional tributary into consideration can solve the problem of the frequency of high-flow pulse processes of a downstream river course being insufficient due to conventional dispatching; and high-flow pulse processes of a downstream river course can be effectively improved, and hydrological conditions required for the mass breeding of fish that spawn floating eggs in a spawning ground are met.
