Abstract: A method for preparing a bisphenol phosphate hydroxyl aluminum salt nucleating agent is provided, which adopts organic aluminum alcoholate as raw materials to prepare bisphenol phosphate hydroxyl aluminum salt. In prior art, a neutralization reaction of bisphenol phosphate and sodium hydroxide is firstly performed, so as to prepare bisphenol phosphate sodium salt; then a double decomposition reaction of sodium salt and inorganic aluminum salt is performed to prepare the bisphenol phosphate hydroxyl aluminum salt. The present invention combines the two-step reaction in prior art into the one-step reaction of phosphate and organic aluminum alcoholate for synthesizing the bisphenol phosphate hydroxyl aluminum salt, thereby simplifying the production process, improving the production efficiency, shortening the reaction time, and improving the product quality.

Abstract: Disclosed are a water-soluble chlorhexidine antimicrobial agent and a preparation method therefor and use thereof. The present disclosure takes hyaluronic acid as a raw material to prepare a hyaluronic acid aqueous solution or organic solution, then the hyaluronic acid aqueous solution or organic solution and a chlorhexidine solution are subjected to a complexation reaction, an insoluble substance therein is removed, and then the resulting solution is dried to obtain the water-soluble chlorhexidine antimicrobial agent, namely hyaluronic acid chlorhexidine. The hyaluronic acid chlorhexidine has a good broad-spectrum antimicrobial performance, and excellent water solubility.

Abstract: A system arrangement and method are provided for allowing the operation of units in a fail safe manner and at low latency. The teachings suggest a specific protocol which allows switching and routing of packages for addressing and controlling light emitting diodes and reading out sensors. The information is distributed according to very specific requirements of the underlying topology and application domain. As light emitting diodes and sensors may affect the reliability of security features in a vehicle specialized approaches have to be provided considering both real-time requirements and reliability. In such a method, a branch device can change its operation mode without an explicit command but, in general, a command may provide an expiry condition of a mode after which the mode returns to its previous mode. Such an expiry condition may be the reception of a predefined number of specific network events.

Abstract: A method is provided to measure a distribution of axial velocities and a flowrate in a pipe or a vessel. The method comprises selecting a single cross-section at a stable-flow segment in a pipe or a vessel, installing a plurality of acoustic wave sensors along a peripheral wall of the pipe or the vessel to form a plurality of effective sound wave paths; measuring sound wave travelling time on each sound wave path; substituting the measured sound wave travelling time data into the model formulas based on a sound path refraction principle for reconstruction calculation to obtain a distribution of axial velocity in the measured cross-section of the pipe or the vessel, u(x,y); and integrating the distribution of the axial velocity u(x,y) along the cross-section to obtain a flow rate. A system is also provided to measure an axial velocity distribution and a flow rate in a pipe.
