The invention discloses an energy-saving type quick start method for a supercritical unit or an ultra-supercritical unit. According to the method, steam from another resource is used for heating supplied water so that a boiler can be indirectly heated, and the thermal stress of a heated surface is reduced when the boiler is started so that the heating rate of the boiler can be improved; meanwhile, the heated high-temperature supplied water is converted into steam-liquid two-phase flow through throttling and pressure reduction, the flowing scouring action of the steam-liquid two-phase flow is far superior to the effect of thermal-state washing, and in other words, the boiler can complete thermal-state washing under the non-ignition condition, and can preheat the whole heated surface before ignition till certain pressure is reached. After ignition of the boiler, due to the fact that enthalpy of subcooling on an inlet of a water wall is eliminated, the problem of water power can be readily solved and the input speed of fuel can be increased. Meanwhile, by adjusting the open degree of a turbine bypass valve, the flow, the temperature rising speed and the pressure rising speed of main stream and reheat steam are controlled, and the temperature rising speed of the heated surface of the boiler is increased; when the temperature of the main steam and the temperature of the reheat steam are larger than the temperature of a turbine heating valve, valve heating is started, and a main machine can early satisfy the impulse starting condition.

The embodiment of the present invention discloses a webpage loading method, comprising: the browser sends a webpage request to the server and loads the overall framework of the requested webpage returned by the server, and loads the content of the first screen of the requested webpage returned by the server to the overall framework Corresponding position; the browser displays the above-the-fold content, and the frame that loads all or part of the above-the-fold content enters the visible area of ​​the browser; when the frame in the visible area changes, the browser judges that the frame in the current visible area needs to be loaded When there is new content, send an acquisition request to the server to request the new content to be loaded; the browser loads the new content returned by the server at the corresponding position of the overall frame, and displays the new content in the current visible area. The embodiment of the invention also discloses a browser, a terminal, a server and a web page loading system. The invention can dynamically load the webpage according to the user's request and improve the response rate of the webpage.

A supported urushibara nickel catalyst is characterized in that the catalyst adopts ceramic as a supporter, SiO2 as a coat and metallic zinc and nickel as active components, the mass of the coat SiO2 is 10-20wt% of the mass of the coat supported supporter, the support amount of the active component Zn is 2-5wt% of the mass of the coat supported supporter, and the support amount of the active component Ni is 3-8wt% of the mass of the coat supported supporter. The catalyst is suitable for bubble reactors, and has the advantages of simple separation, high mechanical strength and large specific surface area.

The invention discloses a simulation testing device and method for bituminous pavement pore water pressure. The device comprises a bituminous concrete sample, an open container and a pressure container, wherein the bituminous concrete sample and the open container are located in the pressure container, the portion between the bottom of the bituminous concrete sample and the opening annular portion of the open container is filled with a bonding agent, the side wall of the bituminous concrete sample is coated with the bonding agent, a first pressure sensor used for measuring outer water pressure of the bituminous concrete sample and a second pressure sensor used for measuring bottom water pressure of the bituminous concrete sample are arranged on the side wall of the open container. The method includes the steps that after the prepared bituminous concrete sample and the open container are placed in the pressure container, the pressure sensors, a piston and a seal pressure container are installed, a control flow path is selected to start testing, and data of the pressure sensors is collected. Directional movement of pore water is achieved through the device, and the response regularity of dynamically-changed bituminous concrete pore water pressure under the external water pressure action can be tested.
