This application discloses a flow control method, apparatus, storage medium, and electronic device, relating to the field of smart home technology. The flow control method includes: obtaining N parameter values ​​from a set of parameter values, wherein the set of parameter values ​​includes at least two of the following: the number of queries processed by the business unit per time unit, the response time of the business unit, the CPU utilization rate of the target device running the business unit, the memory usage of the business unit, and the time node at which the target device runs the business unit; N is an integer greater than or equal to 2; and performing flow control on the business unit based on the N parameter values. This solution addresses the problem that flow control frameworks cannot effectively control the flow of business units, thus enabling better flow control of business units.

The application discloses a microfluidic device and a method for introducing microparticles into cells. The method comprises injecting a microparticle solution and a cell suspension into an inlet channel, and the microparticle solution and the cell suspension are mixed and flow into a main channel. When flowing through the main channel, gas in a microstructure and mixed liquid in the main channel form a gas-liquid interface at a first gap. A piezoelectric transducer is controlled to be turned on, and the piezoelectric transducer generates sound waves. The sound waves make the gas-liquid interface vibrate and generate acoustic vortices near the gas-liquid interface. The acoustic vortices drive the cells and the microparticles in the mixed liquid to gather and rotate. The cells reversibly deform under stress to generate micropores on the cell membrane. The microparticles enter the cells through the micropores on the cell membrane, and the process of loading the cells with the microparticles is completed. The device and the method disclosed by the application realize higher microparticle loading efficiency and solve the problem of uneven microparticle loading effect while protecting the integrity and functionality of the cells.

A machine (1) for emulsifying a food product. The machine conveys a food product from an upstream section past an emulsifier stack to a downstream section by a pressure difference between a pressure in the upstream section and a pressure in the downstream section. To allow improved control of the emulsifying process and potentially allow better flow control of the emulsified food product, the machine further comprises a pressure regulating structure configured to control the pressure difference between the pressure in the upstream section and the pressure in the downstream section.

This invention belongs to the field of solder paste technology and discloses a formulation and preparation method of low-melting-point SMT solder paste, comprising solder alloy powder, a mixed substrate, and flux, wherein the ratio of each component of the solder alloy powder, mixed substrate, and flux is 60:30:10. This invention avoids reducing the mechanical strength of the solder joints, ensures the completion of low-melting-point soldering, and improves the wettability of the solder paste. Simultaneously, by utilizing type A and type B viscosity modifiers to control the viscosity of the mixed substrate and flux respectively, it ensures viscosity quality control during comprehensive mixing. This allows the solder paste to adapt to different process requirements in different application scenarios, improves solder adhesion performance, and provides better flow control, enabling the solder to better adhere to the pad apertures or solder joints during vertical printing or wave soldering. Overall, it improves the soldering performance of low-melting-point SMT solder paste, resulting in good soldering effect and long lifespan.
